There are several methods to check the fuses in your car:
- Visual inspection
- Testing with a multimeter
- Using a circuit tester
Visual inspection
Inspect a fuse in your car to check the continuity of its fuse element. So, if the inner connector has melted, you need to replace the fuse. However, sometimes the wire may appear intact even in a blown fuse.
Testing with a multimeter
First, it is necessary to set your tester to continuity mode (the icon usually looks like a sound wave). Then, touch the two contact terminals of the fuse with the multimeter probes. If the circuit is good, the tester beeps.
Using a circuit tester
The circuit tester is a voltage tester or a lamp connected to wires. To check your fuse, you need to activate a faulty circuit. First, connect the wire of one probe to the (-) terminal of the battery. Then, touch one of the fuse contacts with the wire of the second probe. Repeat this action with the second contact terminal. If one fuse terminal has voltage and the other does not, it means the fuse element has melted.
