It is the circular black unit.

maybe that will help.
I know the issue is the wire that's not connected needs to be hooked up the the Solenoid battery+ then go to the pressure switch then to Solenoid coil+. That will then turn on the compressor when the tank get to 60 psi and shut off around 90-100.
The wire that is not connected has 2ea ring terminals that match the size of the respective studs.
I would just fell more comfortable verifying this first.
If it was a normal coil connection I'd have done it but it has a circuit board on it with 3 wires that go to the other Solenoids and the HWH control.
I do have pictures I could post if I could...not sure how.
For this repeating sequence to happen the HWH leveling system must be left on after it has gone through the initial automatic leveling sequence.
Are you using the HWH system to auto level the coach when you first park? And if so, are you leaving the system turned on?
Anyone have any wiring diagrams or pictures of how this all gets wired? The CC binders are no help.
Mine only works with the key on so as it uses air overnight the compressor never turns on to keep the tank full. The wiring is disconnected from one pressure switch, I'm sure that's the issue.
