What is the best way to locate the short in a 92 Chevy s10 pickup that causes the fuse for the taillights and instrument panel light to blow every time you turn the lights on?

Answer 1

i have a Chevy 4x4 s10 1991, and (it took long time to figure out) my fuse, same as yours, kept burning out. I eventually uni-stalled my stereo and upon reinstalling it, as i plugged in the antenna cord, with the engine on, it sparked, and again my fuse was burned Conclusion: every time previous that i turned on the radio/ (connected to my truck engine) (connected to antenna) my fuse would burn, ~something( a wire) is grounding out (touching metal it is not supposed to be in contact with) ~and causing this failure. i still haven't had a radio re installed, but without it my lights work..so maybe (I'm sure the wires are different from your and my situation) you have a wire that is exposed on some point and the copper inside is touching either another wire or some metal. all of your wiring that has been cut and re connected should be wrapped in tape or having some kind of protective covering on it, it should never just be twisted together with another wire and considered fixed. duck tape works well
