Bit of a wiring lesson happened today.
My rear scene lights/backup lights hadn't worked in a couple months.
Spent about three hours on the weekend taking stuff apart and troubleshooting but to no avail.
I'd reset the breaker, hit the switch and the breaker would trip again.
Fortunatley
@Bikersmurf was kind enough to share his copy of the wiring diagram with me and despite age difference in our rigs the wiring was essentially the same.
It only took about three minutes of reviewing it and I could see the likely problem.. and it was my own dumb fault. When I disabled my door switches (so the lights would not come on when I was camping with them open) I didn't do a good job of capping off the wires. Unbenownst to me the rear door switch is part of the rear scene light circuit. So with wiring harness in hand it only took me about 5 minutes to fix it.
Two quick lessons on ambulance conversions.
1. Always make sure you do a very solid job of capping off any wires that you terminate.
2. Having an original wiring diagram can save hours if not days of work. My backup/rear scene lights quit working and despite about three hours of testing and taking things apart I didn't have any better idea of why.
Lastly, it's pretty cool to be essentially your own self powered repair shop. Running the soldering iron to heat the shrink wrap. (upgrade from my crappy taping job)
