I can't seem to find the earlier wiring diagrams on here, just the ones for 93. Recently I found an 89 d-350 srw, auto truck with cruise control. The wiring is a mess in it. The guy quit driving it because wires started smoking under the dash. There is a constant heavy draw on the battery. I disconnected everything, ran a hot wire to the fss, and arced the solenoid, it barely cranks over and the ground cable gets HOT. Bad ground? Junk starter?
Thanks
