I had posted originally to my bus build thread but that was when I thought it was part of the original Ford wiring harness. I didn't realize my coach electrical problem had to do with the wiring mess
So I reposted in the electrical section.
I got a new 5 pin 40amp relay, reconnected it so that 30 was power from the solenoid, 85 to ground, 87 to the solenoid switch, disconnected the two wires that were wired together and connected them to 86 and 87A and...lights! I've got coach lights, power mirrors, and everything back but now I stumbled onto another issue.
The fan for the rear a/c unit is now working correctly but there's no cold air and the a/c compressor on the side of the bus doesn't look like it's running. A/c was working when we bought the bus a few weeks ago. Also the rear a/c unit's heat is not working either, the dash light now lights up when I switch it to heat but instead of heat, there's a metal box with two fans in it by the wheelchair lift that runs instead!
