My son has an '86 Chevy K-5 Blazer (CUCV), V-8 diesel, 24volt system. He had what we thought was a grounding problem as there were sparks showing up when he cranked the starter. Come to find out the starter was bad, the grounding strap from the solenoid to the starter body was not making good connections. We found this when we were installing a new starter.
The new starter works great, no sparks and it starts up immediately, just bump the starter and it's running. The problem now is, if you turn on the lights the horn honks. Black-outs work fine, but if you move the military switch up, into the service lights position, that's when the horn honks. We did NOT change anything. We disconnected the batteries to install the new starter and then reconnected them. NOTHING was changed, the truck was driven into the driveway an hour before all this work was started.
With it in this condition, he can't drive it as he has no brake lights or headlights for that matter.
After printing up the wiring diagrams and comparing what we've got to the print-out, no luck.
We spent a couple of hours unplugging stuff to try and find a short with no luck.
Anyone got any ideas??? We're going to leave it parked until we find out what's wrong.
