Hey guys. Got a problem that stumps me. I keep blowing the 20 amp Ignition/Guage fuse in my 94 s-10 blazer 4wd. From what I know, it only blows when i slam down on the gas in reverse. If I shift into reverse and go easy, it's fine. I know there has to be some kind of short. I'm just hoping that the detail about reverse would help diagnose it. I have the wiring diagram that shows what goes to the fuse. Anyone have any ideas?

 

What else is on the circuit?


Is your revesrse switch on the the same circuit? If so, look for a bare spot in the wire on the tranny.
