Why does my fuse that works my headlights blow every time i turn on the lights
1996 chevy c3500
I think that the fuse blow up because you have put a low resistance fuse for the lights. For you to place the correct fuse, you may have to know the specs for the fuse. Contact the dealership for more specifications on the model's fuse.
The owners manual should have a fuse panel diagram and fuse value chart. It should also be printed or stamped into the plastic on the inside of the fuse panel lid. You may have a short in your wiring.
Maybe your using the wrong gauge fuze
