How do you fix a short circuit on a car?
The multimeter, set to measure continuity, can be used in a similar way. Disconnect battery positive, set the positive probe on the load side of the fuse, clamp the negative probe to battery negative. If there is a short circuit, the test light will illuminate or the multimeter will beep. Now, divide and conquer.
How much does it cost to fix a short circuit in a car?

How do you diagnose a short circuit 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.
Can you fix a short circuit?
You can do this by unplugging all of your electrical devices that run on the circuit that keeps breaking. Plug in one, and reset the circuit breaker. Continue doing this until you find which device is causing your circuit breaker to trip. Unplug the device before you begin fixing its short.
