Comavalanche Posted September 1, 2016 Posted September 1, 2016 Lost power to my head unit as well as the BATT and PWR ACC terminals on my fuse block inside the cab. I know the head unit works because I took it out, gave it power and it tuned on. Not really sure how to fix this issue...
gogmorgo Posted September 1, 2016 Posted September 1, 2016 You probably knocked something loose. What year and engine? It'll determine what your fuse panel and wiring look like so a circuit diagram can be posted up to help you figure it out.
Comavalanche Posted September 1, 2016 Author Posted September 1, 2016 it's a 1988 4.0. Wiring is a nightmare lol
gogmorgo Posted September 2, 2016 Posted September 2, 2016 http://comancheclub.com/topic/11875-renix-factory-service-manual/ That should help you out a fair bit then. I've even found some of the wiring diagrams useful on my '91.
Comavalanche Posted September 2, 2016 Author Posted September 2, 2016 Thanks for the diagrams man. Lots of useful info!
Comavalanche Posted September 3, 2016 Author Posted September 3, 2016 It's an automatic. The wiring under the dash is such a mess that I couldn't trace the two power wires for the head unit. Maybe I'll feel like looking for it again but I just ghetto rigged it to the fuse panel for now.
