Wiring Diagram For an AirLift LoadLifter 5000 Air Helper Spring System

Question:

Had a mechanic install this on my 2019 ram 2500 4x4 about 2-1/2 years ago while visiting Illinois. Wireless compressor worked wonderful. Great improvement on pulling my trailer. Jump ahead to now, the wireless compressor is no longer working. How should I go about troubleshoot it? Can you send a wiring diagram for the 5000 series system to give me a starting point. Key fob is still working and send a signal as it flashes when changing pressure. Please help Roger Nordlander

I've attached the wiring diagram for you to check out, but it sounds like the compressor for your # AL57289 is not getting power. The wiring harness has an ignition wire which if not connected to an ignition source, will not wake up the compressor and manifold until it senses vehicle movement. You will want to check this wire for power if it's connected to a ignition source.
