Ok an update on my electrical problems

Recommended Posts

1986 MJ, I have tracked it down to somewhere between were the harness comes into the cab. My wipers started working as soon as I grabbed the harness on the outside where it goes into the cab and jiggled it around. So am I to assume I need to pull my harness apart where it goes into the cab and clean all of it or is there another issue I am missing?


I have full voltage under the hood, but only on a few of the fuses inside the cab. My generator light still stays on dim, but alternator and battery are both tested good. I can get my heater motor to work if I jump straight from the fuses box to the switch on the dash. Still no dash lights or horn.
