electrical problems

[stax25]

when you turb the head light switch on it blows the fuse out. I put a new headlight switch in didn't fix it made shure it had a good ground. And every time i put a new fuse in u can smell hot wireing then the fuse blows. and when it blows i lose my dash lights and tail/marker lights. Please help i hate electrical problems

Have you added or messed with any lights. Time to start chasing wires it sounds.

[stax25]

no i haven't changed any lights. All i did was pulled in and turned off the lights came back out turn them on and the dash lights went out along with the rest of the marker/tail lights.

Wet trailer plugs can cause funny things to happen.
If you have trailer wiring, start chasing it there.

Yeah that is a wireing nightmare back there. but the slight smoke and burnt smell comes from in the dash

Investigate anything related to the driving lights and instrument lights.
That includes any aftermarket stuff that may be hooked into the dash lights.

I've found in the past that a short in a tailight many times will burn at a weak point nearest the power supply, which is why most electrical is fused at a point nearest the power supply side.

That you are getting a burning smell tells me either it's fused with a higher rated fuse than it needs, or it gains resistance slowly, then pops the fuse.
Rust buildup and water can do both.
So can a high load device with an intermittant (or vibrating) connection.

just find it before all the magic smoke gets out once the magic smoke is out it is impossible to get it back in

[delinquent]

hope all the smoke does get out. Here is what happened to my buddies 700horse truck. Headlight switch they think caused it.

My 91 was doing something similar. Found the wire bundle had rubbed on the parking brake frame.

Got it fixed was a wired that went into the tailgate for marker lights. It was cut. it was shorting out.

So, the smoke is in the bottle again?

See? All it takes is a little patience.
