Install the adapter and breaker in the fuse box (Photo 1). Then find the short with the meter (Photo 2). Open the wiring harness and locate the chafed or shorted wires and repair them with electrical tape. Reinstall the fuse and test the circuit.

Is it safe to drive with an electrical short?

A short in your vehicle can cause long-term issues that can affect the overall control of the vehicle. They can even be dangerous sometimes, depending on the location of the electrical fault.

How do you diagnose an electrical short in a car?

Set your voltmeter to the DC voltage scale, at around 20 volts, and connect your meter across the fuse holder. If there’s a short in the circuit, you meter should read some voltage. If you are using a test light, you can also connect the light across the fuse holder. When there is a short, the light will illuminate.
