I'm Awesome
I've got a 1992 K1500 with an electrical problem. My courtesy lights and aftermarket tach are flickering, so i've been going through the wiring. I noticed that my ground on the courtesy light was showing .3v with nothing on and the doors closed, but when I opened the door, it showed 12v. I've spent at least 10 hours trying to track this down with no luck. I've got an aftermarket sound system, and instead of dealing with this headache anymore, I was just going to pull the fuse and leave it alone. So I pulled the courtesy light fuse, and the lights went off, but the radio also wasn't getting power. I don't know what the previous owner did with this wiring, but i'm about sick of all of it at thia point. Shouldn't the radio still be working without the courtesy fuse in? It sounds like the 2 power sources are somehow connected, but that still doesn't explain the 12v on the ground side
