hey im new to this thread but I've got a 2000 Dodge Ram 1500 w/ a 5.9L 360. I've had the truck for a while and my tail lights, running lights, and dash lights have stopped working. I pulled the light switch out of the dash and found that 2 wires had all the insulation melted off for about 5 inches and thought that was the problem.

I pulled them apart and wrapped them both in electrical tape and replaced the fuse. It's still blowing the fuse everytime i turn on the switch. I've traced the wires but can't seem to find the problem. Anybody got any advice??

 

Replace the switch and check the ground strap to make sure its fastened snug........

 

the headlight switch? and where is the ground strap?

 

Yes headlight switch,just trace the wiring back under the dash,you'll see it.fastens too a steel support bar..........
