Is the switch one with a light in it by chance? If it is, it wouldn’t hurt to pull the ground wire from it in case the short is within the switch itself. For that matter you can disconnect the output wire and then turn the switch on to confirm the fuse stays intact.

I know this is basically an LED question but I thought it worth mentioning that an incandescent light does not care whether it is AC or DC. It will work on either.

While true you are overlooking most DC lamps are designed for low voltage. Put 120 to a 12 volt bulb and AC/DC will not matter.

Part of my test kit is a 2-prong turn-signal flasher with jumper wires attached. Hook it in place of fuse, will work as auto reset circuit breaker. Then you can follow the wires with non-contact amp meter. When you pass the short the needle will stop jumping.


Laughing. haha. So simple, but so genius.... I will have to add that to my kit one day.
