ARB wiring diagram
I know I should probably just contact ARB, but I would like to see if anyone has something here for me so I don't have to wait for ARB to send me stuff.
My compressor hasn't been getting power, but I know it works (kicks on when it gets direct power).
I would like to just redo the wiring completely, for a few reasons. But that's off topic.
So....anything? Thanks in advance...

I forgot to grab the install packet while I was at my friends place today. I'm going out there tomorrow, though. I just did all mine, so I'm pretty fresh with it.
1. Are you using all ARB components (compressor, wiring harness, locker switches and compressor isolator switch?
2. Are your switches all illuminating correctly?
3. Did you check the voltage at the solenoid and compressor output connectors?
Obviously the two heavy wires in the harness are for the high amperage loop. I'm pretty sure that is just for the compressor. Two wires should have a one way diode in them, red/yellow and blue/white. Red/yellow is the switched 12v power source for the switches, and blue/white is illumination. Other than that, make sure the small black ground wire is properly grounded, because that is the ground for all 3 switches and the high amperage compressor circuit.
The whole harness is set up kind of weird. The compressor switch and switch 1 are both isolators. So if your compressor switch isn't on, you can't engage either locker. And if your compressor and rear locker aren't on, you can't engage the front locker. The switch grounds are set up in series instead of parallel(hence 2 ground plug-ins on each switch) Perhaps one of the switches is bad and can't ground the loop? Maybe the relay that's plugged into the harness is bad?
All speculation, though. Best bet is to engage everything and check voltage at output of each component or wire. Let me know if any of this helped, or if you need some more ideas. I still haven't tested my system either, but I did spend a good bit of time studying up before starting.
If you want to fab your own wiring setup, I recommend using the switch wiring harness and ditching the rest. Let me know if I can help in any way.

Yeah, wiring is not my strong suit. Still using the original ARB setup.
But your explanation does help quite a bit, I just need to get out and check what's going on compared to your notes.
Its real cold, though, so I'm not super excited about doing this.

If you still can't get it to work, let me know an I'll walk you through the connections one by one. My other thought was incorrect wiring of the pressure switch, which almost happened to me... Then again, I'm using the ARB harness and switches with a Viair OBA system.

If it used to work and suddenly stopped, it could be the relay or fuse...
The problem I had with my system was that I was using ARB wiring harness, switches, and solenoids, with a Viair compressor and tank. I had to bridge the red and blue wires that were supposed to go to the ARB compressor's pressure switch because the Viair system had a pressure switch/relay in one.
This caused a similar problem to what you described...
I hope you got everything worked out, but let me know if you still need help.
