Well, ****. There goes $100 I didnt need to spend.

Hit a pothole fairly hard; truck dies. Check fuse, and sure enough, its blown.

Try one from heated seats cicuit and instant pop.

Unhooked steering speed sensor and used a 30amp aux fuse; fired right up.



WTF...?

Just decided to test again, with the sensor hooked up. Fired right up of course, but this time I moved the wires; it stuttered as I moved them and then died.

Wanted to see if I could isolate it to the sensor by unhooking the sensor, then move the wires. Kept running... Then decided to hook the sensor back up just to see. Kept running...

Why me?

Help me help you. So after the bump you replaced the fuse and it ran okay again?

is this popping just as soon as you turn on the key? if so then you ignition switch is likely shorting.

Normally, yes. But she just died again on the highway. Shook every wire i could get a hold of so I could get it back to the house.

Got it home and still had the bezel off. While running, I tugged on the harness for the light switch and thought I heard arching. Moved it all around and indeed heard it. Just didn't understand how just driving down could short it out, but not moving the wire.

Tugged on it just a little harder and the truck died; same fuse popped. Couldn't see what was shorting, but I suppose I can dissect.
