How to Perform an Electrical Fault Diagnosis

Mastering the basics of electricity and diagnosing electrical faults is essential for everyone today, given our increasing daily reliance on electricity. Understanding the fundamental concepts of voltage, current, and resistance can help us identify and solve electrical issues independently. Moreover, with in-depth knowledge of using various electrical diagnostic tools like multimeters, clamp meters, and voltage testers, one can quickly detect and correct electrical malfunctions. However, when handling these tools and electricity, it is crucial to adhere to safety standards to prevent potential accidents.

Understanding the Fundamentals of Electricity

Electricity, that invisible force powering our modern world, is a complex intrinsic scientific concept. Thanks to the continuous development of our knowledge in the field of electricity, we are now able to understand its fundamental principles to perform fault diagnostics accurately and effectively. This guide will provide an overview of these principles—current, resistance, voltage, electronic circuits, Ohm’s Law, and Kirchhoff’s Current Law—in as simple and accessible language as possible.

First, we have current, measured in amperes. It is the flow of electrons through a conductor. Also known as moving electricity, it can be imagined as the flow of water in a pipe.

Next is resistance, which is the property of a material to oppose the flow of electrons, i.e., the current. Measured in ohms, it is often represented by a series of restrictions in a pipe blocking the water flow.

Voltage, measured in volts, is the electrical force that pushes electrons through a circuit. It is often likened to the water pressure pushing water through pipes.

Now let’s talk about electronic circuits. A circuit is a closed path that allows current to flow. Circuits can be in series (where the current has only one path to follow) or in parallel (where the current can take multiple paths).

Next, Ohm’s Law, a fundamental law in electricity, states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance (I=V/R). This principle greatly facilitates the diagnosis of electrical problems.

Finally, Kirchhoff’s Current Law, which states that the sum of currents entering a node (or a connection point in a circuit) is equal to the sum of currents leaving that same node. It is another indispensable tool for diagnosing electrical faults.

With a solid understanding of these fundamental principles of electricity, one can approach electrical fault diagnosis with confidence and precision. It undoubtedly requires some practice to master these concepts, but remember: electricity may seem mysterious and intangible, but it obeys very precise scientific laws that, once understood, can be used to solve a multitude of problems.

Learning to Use Electrical Diagnostic Tools

In the field of electricity, diagnostics are of paramount importance. Diagnostic tools play a crucial role in identifying and resolving issues related to electrical systems. Three of these tools are particularly important: the multimeter, the electrical network analyzer, and the oscilloscope.

A multimeter is perhaps the most common diagnostic tool in electricity. It is a multifunctional device that measures voltage, current, and resistance. To use it, one must connect the multimeter’s leads to the test points in the circuit to get a reading. It is crucial to set the multimeter correctly before use to avoid any potential damage to the multimeter or the circuit.

The electrical network analyzer is another essential diagnostic tool used to diagnose problems in an electrical network. It provides detailed information about the quality of the power supply, such as voltage fluctuations and current harmonics. Correct interpretation of this information can help locate a potential problem in the system.

Finally, an oscilloscope is probably the most complex diagnostic tool. It is used to visualize electrical signals as a function of time. The information obtained can be used to analyze circuit performance and detect problems. Its use requires some expertise and experience, as interpreting the displayed information can be tricky.

These three tools provide an effective method for diagnosing and solving electrical problems. However, it should be noted that their use requires a thorough knowledge of electrical theory. In particular, mastering the fundamental principles of electricity, such as Ohm’s Law and Kirchhoff’s Current Law, is essential to use these tools effectively.

In summary, while the multimeter, electrical network analyzer, and oscilloscope are essential diagnostic tools in electricity, their effective use is deeply rooted in a profound understanding of electrical principles and laws. This is a perfect illustration of how advances in electricity depend on both technological innovation and the intellectual tradition of electrical science. In this context, electricity, far from being a mere practical application, can be seen as a vibrant field of intellectual inquiry and relentless research.

When the bearings tend to fail, the rotation of the rotor would be directly hindered. This can occur due to the buildup of heat and dirt around the alternator.

You will notice a grinding noise that can lead to alternator failure. That’s why it’s important to address the issue as early as possible rather than putting things off until tomorrow.

The Certainty Test

When alternator bearing noise bothers you, performing a certainty test can prove useful. One such test involves starting the car with a booster engine. Once the car’s engine is started, remove the jumper cables.

If the car’s engine stops shortly after, the alternator is to blame. And if the car continues to run, the battery may need to be recharged.

Another test is checking the headlights. Start the car and have someone check the headlights. Keep the car in “park mode” and press the accelerator pedal.

If the headlights tend to dim or if they go out completely, it’s the alternator that’s at fault. You can also refer to maintenance tips to learn about the consequences of a faulty car battery.

How to Solve Electric Parking Brake Problems

If you receive a pop-up on your car’s dashboard and an electric parking brake problem appears, you might wonder what happened to your car. Don’t worry! We are here to help. From faulty brake switches to electrical issues, we will cover everything in this article. Stay tuned to discover common electric parking brake problems and how to fix them.

What is an Electric Parking Brake?

The electronic parking brake is identified by the letter P located in a circle near the gear lever (Photo: wikipedia.org)

Electronic parking brake systems (or electronic handbrake) are becoming increasingly common in popular and high-end vehicles. This type of brake provides the driver with greater safety in stopping and parking situations.

The electric parking brake is identified by the letter P located in a circle near the gear lever or dashboard. The brake is controlled fully automatically; the driver does not need to use the lever but only has to press the vehicle’s electronic handbrake switch. At that moment, the electronic brake will immediately intervene in the vehicle’s braking system, thus eliminating the situation of forgetting to apply the brake or not pulling it within the driver’s reach.

Using the electronic handbrake is very simple; the driver just needs to press the P button to activate it and then shift to P to lock the brake to keep the car stable in the parking position. To release the electronic handbrake, the driver presses the brake pedal and then presses the P button. At that point, the handbrake warning light will turn off, indicating that the handbrake has been released.

Let’s review some advantages and disadvantages of using the electronic parking brake in your car:

Advantages

  • The electronic parking brake (EPB) was developed to optimize the safety braking function in cars, minimizing the dashboard and interior space. Thanks to this, vehicles using this type of handbrake are considered more luxurious and modern.
  • The electronic handbrake has the feature of automatically disengaging when the vehicle is moving and automatically maintaining the brake when the vehicle stops on a slope, which will ensure safety while driving a car.
  • The electronic braking system may not encounter problems such as mechanical parking brake errors or brake lock-up if the vehicle owner does not regularly maintain the vehicle. This is possible due to advanced design and operating principles. And this will help reduce maintenance costs for drivers.

Disadvantages

  • Due to modern technology and more complex operations, electronic handbrakes cost more to produce and maintain than conventional mechanical brakes. Electronic parking brakes have a shorter lifespan than normal mechanical parking brakes if they are not periodically inspected and maintained.
  • Furthermore, when the battery is depleted, the electronic parking brake may not function. Additionally, when using electronic brakes, drivers may sometimes notice a slight vibration in the vehicle.

Despite some superior characteristics compared to the mechanical braking system, the electric parking brake still has issues with the driving process that you may encounter when using this type of brake. If you notice the following problems, the car owner should immediately entrust the vehicle to a trusted mechanic to have the electronic parking brake checked.

Most Common Electric Parking Brake Problems

The risk of electronic parking brake failure is lower than with mechanical handbrakes, but it can still happen. Below are the most common problems associated with using electronic handbrakes:

  • Electrical Errors

We believe this is the most common problem associated with using electric parking brakes. Electric parking brakes rely on an electrical system to activate and release the braking mechanism. Electrical malfunctions can occur due to wiring issues, connectors, or a blown fuse. If there is a problem with the electrical components, the parking brake may not engage or release as expected. If the parking brake does not engage or release when activated, it may require inspection and repair by a qualified mechanic.

  • Sensor Problems

Many sensors are integrated to monitor the braking status and ensure the proper functioning of the electronic parking brake system. If there is a problem with the sensor, such as a faulty or misaligned sensor, it may provide incorrect feedback to the system, leading to parking brake malfunction.

  • Mechanical Problems

The electric parking brake system consists of mechanical components such as cables, calipers, or actuators. Over time, these components can wear out, become misaligned, or get stuck. Mechanical failures can prevent the parking brake from functioning correctly, leading to issues with engagement or release.

We can see that the main cause of parking brake malfunction is a short circuit or open circuit in the wires or circuits between the switch, controller, and actuator. When the braking system fails, the brake light on the dashboard activates so the driver can detect the problem and fix it. Additionally, you may notice a burning smell due to the vehicle’s electronic handbrake being stuck and not functioning. And it is possible that the brakes wear out because the handbrake is still engaged while the vehicle is moving.

How to Test the Ignition Switch – Two Different Methods

A faulty ignition switch can cause many problems. It can lead to the shutdown of certain electrical components, the car not starting, or stalling immediately after starting. You may need to replace the switch if the problem becomes severe or if the car does not respond at all. But you need to know how to test the ignition switch to determine that it is actually broken and needs to be repaired.

Symptoms of a Faulty Ignition Switch

Know the symptoms before concluding that you need to replace the component or learning how to test the ignition switch. A faulty switch will display these signs to warn of a potential problem.

Sudden Vehicle Stalling

This is the main sign that the ignition key is failing. If the failure occurs while the engine is running, it can cut power to the ignition and fuel system, causing the car to stall.

The Car Stalls After Starting

This happens when the switch fails in the “ON” position. It may power the fuel and ignition systems when the engine starts but stops working immediately after.

Problem Powering Accessories

Turning the key to the “ACC” position should power the accessories. If this does not happen, there must be a problem.

How to Test the Ignition Switch: The Procedure

The function of this component is to provide voltage to the ignition control module and the ignition coil. The ignition system has two wires connected to the switch’s operating terminal. One goes into the module and the other connects to the primary resistance and the coil. The switch’s start terminal also has a wire connection to the module.

To inspect the ignition switch, it must be removed from its location and the resistance and continuity checked along all terminals. Before removal, it is necessary to check if the connections to the switch are working.
You can check the switch’s voltage using two tools: a 12-volt test light or a digital multimeter.

How to Test the Ignition Switch with a Test Light

Step 1: Disconnect the wire connector from the module after turning off the ignition. Also disconnect the S terminal from the starter solenoid. This will prevent the engine from starting even if you turn the ignition key to the ON position.

Step 2: Turn the ignition key and place it in the ON position. Probe the red wire connection to test for voltage. Do the same at the ignition coil’s battery terminal.

Step 3: Next, turn the switch to the start position and probe the white wire connector from the module and the ignition coil’s battery terminal to check for voltage.

The circuit and switch are faulty if there is no voltage.

The Hidden Costs of Owning an Electric Car

Before saying goodbye to gas stations, discover the hidden costs of owning an electric car to prepare yourself well for new road routes!

In an era where gasoline prices are soaring and electric vehicle (EV) charging costs are significantly reduced by manufacturers, buying an EV is probably an obvious choice. But the economics of electric vehicles is a complicated story, and you need to understand many unknown issues before deciding to say goodbye to gas stations.

Hidden Costs Associated with Owning an Electric Car

Buying a New Electric Car

To drive an electric vehicle, you first need to buy the car, and it’s not cheap. Even if you sell your existing gasoline car, you will likely have to shell out at least $10,000 more. This decision will take many years to reach the break-even point, even if you just buy a very cheap electric vehicle, live in a place with low electricity prices, and always charge your car at home. Too many “ifs” make buying an electric car difficult to consider as an economical option.

In reality, many people buy hybrid or other fuel-efficient vehicles at a net cost much higher than what they could save on fuel when using them.

Of course, a fully electric car will save you much more energy than a hybrid car, but its initial purchase price, along with insurance and repair costs, can lead to less positive economic outcomes. On the other hand, traditional gasoline cars often involve many minor maintenance costs that electric vehicles don’t have, such as oil changes or brakes.

Many people even give the reason for buying an electric vehicle to protect the environment. This goes beyond the scope of the article, but you might think of ways to protect the environment much more effectively than investing money in electric cars.

Resale Value

Price depreciation happens with any vehicle you buy and is a very important factor to consider for electric vehicles. The value of a new car will always decrease once you drive it home, leading to generally higher per-mile costs for electric vehicles due to the selling cost. And it wasn’t cheap, and the price drop rate has been faster than that of traditional cars.

For example, Subaru, even though not renowned for its electric vehicles, has an average resale value of 66% of its new price after five years of use. Assuming a new Subaru costs $35,000, this price drop will cost you $11,500 over the first five years, which is $6.3 per day.

Meanwhile, a Tesla with a higher average price will retain 58% of its value after 5 years (this is why Tesla ranks 3rd on the list of luxury car brands). In other words, if you buy a Model 3 for $60,000, you’ll have to accept a “loss” of $25,000 over the first 5 years, which is $13.8 per day.

Ultimately, most people know that as soon as you drive a new car off the lot, it loses value. This loss is also amplified when it comes to electric cars. Here are some reasons why electric vehicles depreciate over the years:

  • New electric cars benefit from a tax credit of over $7,000 (with some limitations). For example, once this tax credit is canceled, the value of a car can drop by up to 60% at the end of a three-year lease.
  • Electric vehicles lose up to 20% of their maximum range after 5 years.
  • Electric car technology is still new and evolving rapidly. Like the latest smartphone compared to a three-year-old model, new EV models will be much more attractive to buyers than older models, especially as battery technology improves.

Battery Replacement

Another form of depreciation that only occurs with electric vehicles is that after a period of use, the battery needs to be replaced. Unlike a traditional car, which has a non-replaceable engine, the EV’s battery must be replaced when the vehicle operates to a certain point and can no longer maintain the original range. Battery replacement costs vary by vehicle, but the average estimate is around $10,000.

However, this figure is just an estimate, as very few EV models have been in operation long enough for the battery to degrade to the replacement point, and the replacement battery market is not as crowded as the traditional automotive parts market.

Overall, unlike standard car batteries, electric car batteries are not cheap. They perform well for 100,000 miles but cost between $10,000 and $20,000. Furthermore, EV battery technology will improve over the next few years, and their prices are expected to drop. But if you want to increase the mileage, you need to think about how you will pay for a new battery. Certain conditions can lead to faster degradation of an electric car’s battery.

For example, using ultra-fast DC charging will reduce the battery’s lifespan. Kia also notes that fast charging leads to a 10% decrease in battery life over 8 years.

Additionally, for electric vehicles that are bought and sold over and over, we don’t know who will be responsible for battery replacement. If you buy a used electric vehicle, expect that you will be the owner and will have to spend your own money to replace the car’s battery once its range decreases, thus making the car’s depreciation problem even more challenging.

Registration Fees/Gas Tax

The gas tax, which is levied at the pump in some states when refueling a gasoline vehicle, is used to help pay for road repairs. Since electric vehicles don’t use gasoline, states impose additional registration fees of about $50 to $200 for electric vehicles. Currently, Georgia has the highest electric vehicle fees, but check the full list of states and electric vehicle registration fees for more information.

Insurance Premium

Most car insurance companies charge higher fees for electric cars because their repair and replacement cost more, and fewer repair shops have staff trained on electric vehicles. As a result, you will pay between 5% and 20% more for electric car insurance than for a gasoline car.

Roadside Charging Stations

Even though it’s certainly cheaper to charge an electric car than to pay for a gasoline car, your actual savings will be significantly lower if you charge it on the road rather than at home. The price of public charging facilities varies considerably, some charging by minutes of charging and others by kWh of electricity used. Although DC fast chargers can cover 100 miles in 10 minutes, they are also the most expensive public charging option. However, convenience and charging time are also factors to consider.

Home Charging Source

Although it is by far the cheapest charging method, home charging for electric cars also has drawbacks. It may be less expensive to charge the electric vehicle with a Level 1 charger using a standard 120-volt outlet, but this option is not practical if you drive daily, as this type of charging can take 24 to 36 hours in cold climates. This means daily commuters need a more expensive Level 2 electric car charger installed by a professional for convenient overnight charging.

EV chargers typically cost around $2,500 for the charger and installation, and EV chargers have a lifespan of about ten years. If your home needs an electrical upgrade to accommodate a Level 2 charger, you will have to pay extra.

Range Loss (Battery Performance)

As mentioned above, electric vehicle batteries degrade over time. So, as your car ages, a fully charged battery will allow you to travel shorter distances than before. Additionally, cold weather affects the performance of EV batteries.

Repair Cost

Electric vehicles have much more complex electrical systems than traditional gasoline vehicles. And these systems are often very expensive to repair or replace. Furthermore, electric cars often have parts that are hard to find and replace, which can also increase the actual cost of owning an electric vehicle.

On average, over a three-month period, repairing an electric vehicle costs twice as much as repairing a gasoline car. Over a year, the cost of an EV service would still be more than double the cost of an ordinary vehicle repair. The average repair cost for an electric vehicle is about $300 per electric vehicle, while a gasoline vehicle with an internal combustion engine costs an average of about $150.

Another important factor in electric vehicle repair costs and the true total cost of owning an electric vehicle is the maintenance of the EV battery. Most other electric vehicles run on lithium-ion batteries. They are similar to the batteries in your phone or laptop but are much larger. Lithium-ion batteries degrade over time, and the lifespan of EV batteries is typically 10 to 15 years.

Another hidden cost associated with owning an electric car is the cost of spare parts. Electric vehicles often have parts that are hard to find and replace, which can increase the cost of ownership.

Furthermore, many auto repair shops have mechanics who are not familiar with electric cars for obvious reasons. This means it will take mechanics more time to diagnose and then fix the electric vehicle’s problem, thus adding more dollars to your car repair bill.

Buying an Electric Car Is Not Easy

Thus, the cost of purchasing and using an electric vehicle is much higher and fluctuates depending on where you live or how much you have to pay for electricity.

For example, in California, the average cost of electricity is 18 cents/kWh, while in Idaho, it’s 8 cents/kWh, and in Hawaii, it’s 28 cents/kWh. Additionally, the electricity bill is not always clear. Everyone knows that there are times of the day when electricity prices will be lower than usual, and don’t forget the associated taxes.

A quick comparison on the U.S. Environmental Protection Agency website shows that the Tesla Model 3 Long Range consumes much less energy than the BMW 330i xDrive (gasoline car), suggesting that Tesla seems to be a great option if you want to save money. But a 2021 study by the Anderson Economic Group concludes that driving an electric car can cost much more than driving a traditional car.

Driving an electric car can be either cheaper, as expensive, or more expensive than driving a gasoline car. An electric car actually helps reduce travel expenses, except for longer trips. The shift to electric vehicles is inevitable for technological, political, and financial reasons, but what you need to know is whether the cost of using an electric vehicle suits your situation and economic condition. How you use electric vehicles will help protect the environment.

Are Electric Cars Worth Owning?

It is currently too difficult to answer this question because there are too few electric vehicles on the streets. Even though electric vehicles have clearly made a breakthrough in the local automotive industry, there is still too much work to be done. When the time comes, electric cars will certainly become cheaper than gasoline and diesel cars.

Conclusion

We have just scrolled through some information about the hidden costs associated with owning an electric car with our article above. We hope to see you again with more insightful car maintenance tips!

Reasons Why Your Alternator Isn’t Charging the Battery and How to Fix It

Have you ever noticed signs that your car battery is weak or failing to charge, even if it’s a new battery? Could the alternator be the cause or not? Let’s go through this guide to discover the common reasons why your alternator is not charging the battery and the simple steps to fix this issue.

The Main Functions of a Car Alternator

The alternator is one of the 5 main components of the car’s electrical system, functioning as a machine that generates energy to power the battery, serving the operation of charging devices and electrical equipment.

Car alternators produce electricity by converting mechanical energy. Notably, the source of mechanical energy can come from internal combustion engines, solar energy… If you tried to start your vehicle without an alternator, the battery alone would not be able to produce enough energy to turn your engine over even if you have a new car battery. The alternator is necessary to keep the battery charged and alternate the electrical current through many components of your car.

A faulty car alternator will affect the charging process and the operation of the battery. At the same time, the car’s electrical equipment also operates abnormally and cannot function at its maximum capacity. So why is my alternator not charging my battery? Let’s find out the causes in the next part:

Without an alternator, the battery alone would not be able to produce enough energy to turn your engine (Photo: nationwide.com)

Alternator Not Charging the Battery: 6 Common Reasons

If the car’s alternator stops charging your battery, it’s as if your car cannot start. However, if you are lucky enough, in some situations, your car will probably run for about 10 minutes, but after that, the current will be immediately cut off. Knowing the reasons will help you diagnose the exact problem and possibly fix it.

Generally, a common cause for the alternator not charging is minor wear or corrosion. Practically all mechanical failures, whether it’s brush wear or bearing failure, are the result of an extended lifespan. Modern alternators are equipped with sealed (maintenance-free) bearings that only need to be replaced after a certain time or mileage. The same goes for the electrical part: often, the entire device must be replaced. Besides these causes, other reasons can be considered and checked:

1. Blown Fuse

Some models have alternators that depend on a particular fuse to function. However, sometimes this fuse can blow due to a power surge or simply due to old age. At that moment, your alternator will no longer charge the battery. But remember that not all have fuses, so you must consult the owner’s manual to see if your alternator needs fuses or not. After that, we will give the exact diagnosis.

2. Bad Alternator

Another common issue could be that the alternator is not working or is poorly connected. To test this, you can apply a multimeter in Voltage mode. Start your car and then use a multimeter to check the car battery voltage. The normal number should be around 13 to 14.5 volts. If it’s lower, try revving the engine a few times to see if the voltage increases or remains low. If the Voltage does not exceed 12.5 Volts, the battery will not be charged and the alternator will not work.

A good alternator correctly designed for your engine will provide the charging voltage as described even at idle, even if it may drop below 13 V.

3. Bad Alternator Brush

Carbon brushes constitute only a small part of the alternator but play an important role. Because it is a conductive material and it is responsible for transmitting electricity, connecting the electricity from the static part (Stator) to the rotating part (Rotor).

When the alternator brush is damaged, the electromagnetic connection between the two parts above will be interrupted. Carbon brushes often encounter problems such as oxidation due to long-term use. Carbon brushes are worn out and the brush springs are broken.

4. Stator Winding Problems

The stator coil is made of a core and a coil placed in the front frame. It is responsible for generating a three-phase alternating current through the variation of the magnetic flux of the rotating rotor. When this part is broken or grounded, electricity will not be produced and the power generation will not be able to supply energy to many systems.

5. Alternator Rotor

The rotor is a magnet inside the stator coil. It is responsible for creating a variable magnetic field inside the stator coil. The magnetic field creates an interaction with the stator winding and generates electricity. When the rotor coil is damaged, the magnetic field is not created and no current is generated, which affects other functions of the car.

6. Regulator

As its name suggests, the regulator is responsible for regulating the voltage of the current emitted by the generator system to keep it always stable. If this part is damaged, the electrical current will be weak and strong, causing other parts of the vehicle to flicker such as the lighting system and the car starter.

Symptoms of a Bad Alternator

If you detect any of the symptoms below, you should have your alternator checked:

Difficulty Starting

If you turn the key to start but the engine cranks weakly and starting takes a long time, it could be due to a faulty alternator, which prevents the battery from charging and the voltage is not sufficient to start the engine. Quickly taking your car to a trusted mechanic to have it checked is the safe method. In this case, you should also turn off some electrical equipment like the air conditioning, radio, or headlights to save energy.

The Battery Light Turns On

Normally, when starting the engine, the battery light turns off to inform the system of normal operation. But when the car is running and the battery light is still on, it could be due to a weak, damaged battery, or a problem with the battery charging system. The light is on to signal this malfunction.

Dim Headlights

Because the alternator powers the vehicle’s accessories, the lighting system, etc. When this part has a problem, the headlight system will be weak, dim, and flicker. Therefore, if the car lights are weaker than usual and flicker, it is a sign that you have a faulty alternator.

Strange Smell

This smell could be due to the wire heating up because the moving pulley is not aligned or not rotating freely. From there, a significant friction force is created on the belt and that part of the belt heats up, creating an unpleasant smell of burnt rubber. And then, the car’s alternator can be broken.

The alternator is an important component that allows the battery to be charged and powers all the car’s electrical devices. If this device has a problem, it will greatly affect the operation and movement of the vehicle. Knowing how to check a car generator will help drivers know its condition so they can handle it promptly.

But testing the alternator is a rather complex process, it requires experienced technical personnel and the help of different types of tools to know the exact cause. However, if you have basics in the automotive industry, you can perform this procedure entirely by yourself:

How to Test a Car Alternator?

The alternator is not charging the battery but the alternator is good. What should we do? (Photo: pinterest.com)

To check the alternator, you need to prepare a professional test kit and a voltmeter.

Follow these 3 steps to test your alternator:

Step 1: Test the Battery

To check the battery, we use a voltmeter. Attach the red wire of the voltmeter to the positive terminal of the battery and attach the black terminal of the voltmeter to the negative terminal of the battery. Then read the settings.

If the voltage is above 12V, we can proceed to the next step. Conversely, if it is below 12V, you need to charge the battery and re-measure the voltage after charging.

Step 2: Start the Car

After measuring the battery voltage, press the accelerator to let the engine run. You need to increase the accelerator to a speed of 2,000 rpm to let the engine warm up after a long period of inactivity.

Step 3: Let the Engine Run Steadily and Check the Battery Voltage.

Let the engine run steadily and check the battery voltage. Continue reading the voltmeter value. If the car battery voltage is between 13 and 14.5 V, the alternator is functioning normally.

If the voltage value is lower or exceeds the threshold of 13 to 14.5 V, it means the generator is faulty or has a problem. Furthermore, it is necessary to continue checking the operation of electricity-consuming devices like air conditioners, lights… to see if they are working normally.

How to Fix an Alternator That Is Not Charging

Upon detecting signs of damage on the vehicle, the recommended method to remedy this situation is to take the vehicle to a repair garage so that technical staff can perform an inspection, detect the right ailment, and treat it with the right medicine.

In the case where the car breaks down in the middle of the road, or if it is suspected that the alternator is damaged, causing the battery to discharge and making it impossible to start the engine and drive, you can call roadside assistance for help or test the battery regulation yourself if possible.

Additionally, you should also maintain the electrical system as well as the alternator regularly, periodically every 3,000 km – 5,000 km of operation (equivalent to about 3 to 6 months) to increase longevity and limit and detect generator damage as soon as possible.

How to Keep Your Car’s Alternator in Good Condition

Mastering the following tips will help drivers maintain their car’s alternator in ideal operating conditions. Specifically:

  • Regular Maintenance: during regular maintenance, all parts of the vehicle will be checked. If the alternator has a problem, it will be promptly maintained/repaired to avoid serious damage.
  • Limit the Use of Multiple Electrical Systems at the Same Time: Using multiple electrical loads at the same time will cause the alternator to operate less stably. Therefore, this must be limited to maintain the operation and durability of the car’s alternator.
  • Replace the Belt at the Right Time: One of the keys to extending the alternator’s lifespan is checking the belt. As it is made of rubber, the belt frays and cracks over time, typically between 40,000 and 70,000 miles – although there is no precise schedule. That’s why it’s important to check the belt during routine maintenance. Replace it after noticing the first signs of aging as it can damage your engine.

How to Test a Car Battery

The battery is a very important component of a car. Regular battery testing can ensure it’s ready to start your vehicle under all conditions. Your vehicle’s entire system depends on it and proper maintenance. To keep your best car battery in perfect condition, it’s essential to know how to test a car battery. If you haven’t tried it before, don’t worry. Here, we will present 6 amazing ways to do it.

How to Test a Car Battery in 6 Interesting Ways

Regularly testing the car’s batteries and electrical systems helps your car function correctly and reduces the risk of breakdowns. Here are the 6 most common ways to check your car battery.

#1. Voltmeter

A voltmeter is necessary to perform this trick. (Photo: sageGEEK)

To understand how to test a car battery, knowing how to use a voltmeter is very important. There are 2 types of voltmeters you can select to test your battery. One is analog and the other is a digital voltmeter. The best solution is to choose a digital voltmeter, as it is easier to read and gives you a precise measurement. However, there are certain things drivers should know:

First, carefully check your car’s ignition before the procedure. Ensure the car’s ignition key and all lights are turned off. Second, car owners must remove the cover from the battery’s positive terminals, check these terminals, and clean them properly. Third, always remember that the voltmeter’s positive wire must be connected to the battery’s positive terminal, which is red. Meanwhile, the voltmeter’s negative wire is connected to your battery’s negative terminal, which is mostly black. Fourth, after completing these parts, you can see that the voltmeter will display results based on the battery’s condition. Volts from 12.4 to 12.7 indicated that the vehicle’s battery was in good condition.

In the voltmeter result, when you see a value lower than 12.4 volts, it means your battery is weak and needs to be recharged to improve. If the value is below 12.2, slowly charge your battery and check again following the same steps. On the other hand, if the value is above 12.9, it indicates your battery has an overvoltage. So try turning on the high beams to remove the excessive voltage charge.

To learn more, watch this video on how to check a car battery with a voltmeter or multimeter.

#2. Ammeter

The ammeter is normally used to measure any flow. In many vehicles, the ammeter is pre-installed, which is very helpful and useful.

It tells you the battery’s charge status. This meter also informs whether the charge is entering or leaving the battery. This lets you know if the alternator is charging the battery or not, due to the heavy load. It will give an accurate indication of the battery’s good condition. If the charge is ridiculously low, you will then be sure the battery is weakening. When learning how to test a car battery, drivers need this tool because it gives much faster results than a voltmeter.

https://youtube.com/watch?v=Ge0H9s4mjsU%3Fstart%3D35%26feature%3Doembed

Watch the video explaining how to use an ammeter to test your car battery.

#3. Battery Health Indicator

The battery health indicator is usually pre-installed in many vehicles. If you want to know how to test a car battery, this is one of the most important devices. Old cars don’t have it installed, but it can be installed if you wish.

The round glass cover indicates the battery’s condition, and based on this, you can maintain your battery.

By turning on the ignition, the arrow will point near the division between the red and green bands. When the circle is green in color, your battery is in good health. The red circle indicates your battery is operating with a lower charge and needs to be given a proper charge to function normally.

When you see dark black or clear color, it means the battery is depleted or discharged and you need to replace it quickly.

#4. Power Probe

Testing will be much easier with the Power Probe test. (Photo: Amazon)

A power probe test device is a faster way to know how to test a car battery. It’s a simpler way to test a car battery than a voltmeter:

To start, drivers must remove the cover from the battery’s positive terminals. After that, the device’s positive wire connects to your battery’s positive terminal. Then, connect the Power Probe’s negative wire to the negative terminal. The probe’s tip is then attached to the battery’s positive terminal. Finally and most importantly, if the battery is below 12.2 or above 12.9, we recommend following the steps mentioned above in the voltmeter method. Areas where the weather is mostly cold will be particularly beneficial for the power probe.

https://youtube.com/watch?v=GdH-e4Q9p5k%3Fstart%3D12%26feature%3Doembed

You can have a clearer view of how to test the car battery with Power Probe by watching the video below.

#5. A Hydrometer Check

The powerful device for testing a car battery. (Photo: YouTube)

A fluid device for measuring the battery is known as a hydrometer. This is used to measure the battery’s specific gravity to determine its state of charge. It also determines the strength or weakness of the battery acid or fluid. However, this method is useless for knowing your battery’s capacity.

Generally, a fully charged battery, when tested by a hydrometer, should have a specific gravity between 1.265 and 1.299 at 80°F (26.7°C). Use the manufacturer’s specifications for your specific battery to determine the acceptable range of specific gravity readings. If the readings are below the acceptable range, it may indicate a weak or discharged battery.

Capacity depends on the number of plates present in each cell. If any of these plates are damaged, the cell’s capacity is affected. For a sealed battery, this method might not work.

However, please note that testing a car battery with a hydrometer provides a general indication of the battery’s health status. For a more accurate assessment, you might consider using a battery load tester or consulting a professional mechanic.

#6. How to Test a Car Battery with a Battery Load Tester

You must check that the terminal is disconnected from the battery. The positive fine gauge of a battery load tester must be connected to the battery’s positive output.

Later, the negative wire will need to be connected to the negative output. Keep in mind that some battery cable testers don’t have a negative output, but there is a pin connector on the other side of the tool. You must touch the car battery’s negative output if you have a pin connector. The tool will not work for more than 5 seconds and later, it will connect to a car battery. There will be sparks when the car battery touches the pin connector. This means everything is going as it should.

https://youtube.com/watch?v=3QiKyjWWiRo%3Ffeature%3Doembed

The voltage rate will drop to 10-10.5 V if the battery is in good condition. The voltage drops to 9 V, meaning you will soon need to replace the battery with a new one.

Conclusion

Here are the 6 most useful ways to test a car battery for you. Perform regular checks on your car battery to avoid any problems and also to extend your car battery’s lifespan. Let us know if these techniques work for you.

How to Recondition a Car Battery in 5 Steps

A car battery is one of the most expensive pieces of equipment that you want to keep in the best condition for a long time. A bad battery replacement can be costly, but not when you have an effective DIY guide on how to recondition a car battery solution. Yes, you read that right! You can easily recondition your car battery with our foolproof method. So first, let’s find out what car battery reconditioning is!

What Are Reconditioned Car Batteries?

Reconditioned car batteries refer to the process of restoring the healthy life and charging capacity of your old and dead cells. It would be a total waste to easily throw away your old batteries when you can still recondition them one to three times.

So, instead of throwing away the batteries. Let’s learn how to recondition a car battery at home. You will be able to learn it in the next section of our article.

Why Should You Recondition Batteries?

What we always see are people throwing away their car batteries. It’s understandable since no one wants the hassle and inconvenience associated with using batteries that are no longer effective. Likewise, drivers have no idea how to recondition batteries. Batteries are also incredibly expensive to replace, and their price might not even go down as the device ages.

Battery reconditioning allows you to preserve and refresh the function of your batteries so they can perform as before: giving you enough charge and saving you a lot of money. It is also better for the environment since the batteries themselves are very difficult to recycle and usually end up in trash cans, leaking chemicals into the environment and having a huge impact on the planet’s well-being.

So, let’s explore the entire procedure for reconditioning a car battery right now!

Let’s learn how to recondition a car battery at home. (Photo: pinterest.com)

Use a Clever Way to Recondition a Car Battery

Reconditioning your car battery is not complicated at all. Just follow a complete procedure and do it yourself every time.

What Equipment Do You Need?

Please prepare these tools in advance to recondition the car battery!

  • Battery charger
  • Chemical-resistant neoprene
  • Safety glasses and gloves
  • Flat-head screwdriver
  • Plastic funnel
  • 1 gallon of distilled water
  • Plastic bucket
  • Voltmeter
  • 1 lb of baking soda
  • Optional battery terminal cleaner

How to Recondition a Car Battery

Step 1. Reconditioning the Basics

At the initial stage, cleaning corrosion is vital. You can use a ready-to-use post cleaner or prepare your own solution to clean the battery terminals. You can also choose any cleaning product available on the market. To prepare your solution, mix 2 teaspoons of baking soda and 1 spoon of water until you see it turn into a fine paste. Now, take a toothbrush and scrub it on the posts. In case of heavy corrosion, you can even use steel wool. This is the first step towards how to properly recondition a car battery.

If your battery has heavy corrosion, using 300-grit sandpaper or steel wool is a great choice.

Note: Remember to wear safety equipment like gloves and glasses.

Step 2. Check the Battery Voltage

The next step to restore the car battery is to check the battery voltage. The voltage tester voltmeter is the best choice with which one can obtain the correct power settings. There is nothing complicated about checking the voltage, just connect the voltmeter to the battery terminals and you’re good to go.

The condition for reconditioning a car battery is that the battery voltage is above 10 volts. If the readings are 12.6 Volts, the battery is in good condition, and if it is higher, reconditioning is surely necessary. If it is between 10 and 12 volts, you can restore the battery to full function. On the other hand, if it’s less than 10 volts, you’re probably wasting your time. You might see a zero reading. This indicates that the battery has short-circuited. This is the time when you need to use your maintenance tips or simply contact the mechanic to handle the situation the right way.

Step 3. Remove the Acid

Do not use tap water as it contains chemicals harmful to a battery (Photo: istockphoto.com)

After successfully checking the voltage, it’s time to remove the old acid from the battery. Using a flat-head screwdriver, reach the battery caps. The caps can range from two to six. Remove all caps but make sure you have a container or bucket near you.

At this stage, before emptying each cell, you should take the time to test each battery cell individually. This could help you find out if your car battery has a dead cell or not. When the battery cells are all empty, set your battery aside, take ½ lb of your baking soda, and add it to your bucket of used battery acid. This will neutralize the battery acid so you can safely dispose of it later.

Note: The liquid (electrolyte) inside lead-acid battery cells is very dangerous. It is a mixture of sulfuric acid and water. You don’t want to get it on your skin, in your eyes, or even on your clothes. So make sure to wear all safety equipment.

Step 4. Restore the Battery to Working Condition

Now that you have cleaned the acid from the battery, it’s time to recondition it. For this, you need to fill the cell with electrolytes. The electrolyte is normally made of Epsom salt and distilled water. This will allow your battery to charge well and avoid sulfates. Now, pour it into the battery.

Step 5. Finally, Charge the Battery

The final step in reconditioning a car battery is to check if the entire reconditioning process is working or not. It is not recommended to put the caps back on the battery as the electrolyte might overflow during charging. So, take the battery charger and connect the black wire (negative) to the negative terminal and the red wire (positive) to the positive terminal. Maintain the charging speed around twelve V/two amps. Continue charging for at least one day or 36 hours. Remove the charger and take the readings via the voltmeter. Normal readings will be 12.42 V. You can also perform the battery load test if you wish. Otherwise, you are ready for an effective car battery.

There you go, you have completed the task of reconditioning a car battery. Remember to wear safety glasses, gloves, and other important things.

Tips and Warnings When Reconditioning the Car Battery

Tips

Unless you use car batteries for a few weeks or more, put them on a maintenance charger to limit performance loss. A stored battery gradually loses its charge, allowing sulfur to form on the lead plates.

To restore the battery to its maximum capacity, put it on the charger for three or four nights.

Do not put the caps that cover your battery’s cells back on during charging, as the electrolyte fluid is likely to heat up and overflow. You don’t want pressure to build up inside the cells.

Warnings

Do not use tap water as it contains chemicals that would damage a battery

Car batteries contain very dangerous sulfuric acid. You must work only in a well-ventilated area and with no open flames nearby. Wearing safety glasses and rubber gloves is also recommended. In an unfortunate case, if you get acid on your skin, irrigate it immediately with water.

Alternatives to Epsom Salt Battery Reconditioning

Normally, Epsom salt is used because it gives the best results. However, there are a few alternatives to Epsom salt that you can try for battery reconditioning.

Aluminum Sulfate

You can mix 1 lb of aluminum sulfate with 1 gallon of boiling distilled water. Stir this mixture until it is as clear as possible. Then you fill the cells with the solution and charge the battery. As a result, the battery charges faster thanks to the electrolyte produced from aluminum sulfate.

Copper Sulfate

Copper sulfate is another substitute for battery reconditioning. From our experience, it is not as effective as Epsom salt, which remains the safe choice.
