At its core, a short circuit is a fault in the wiring harness, which shunts electricity between circuits before it reaches its destination. A short circuit should not be confused with an open circuit, in which current does not flow at all. Although the symptoms of a short circuit can be similar to those of an open circuit, the diagnosis is a bit different. There are several ways to cause a short circuit, and it is generally not easy to find and repair. To understand how to find a short circuit, however, we need to understand how a properly functioning circuit works.
