Steve,
I am pretty new here. Can you direct me to the section you are referring to? We found some manuals on the Power Gear Site; but they were focused on operating the Unit, not on the wiring.
We had someone working on the unit to repair a leak in the system. He unplugged the wires from the 5 plug-ins on the selanoids without marking their original location, couldn't get a replacement pump, and just left it that way. My husband has the unit working to level the motorhome, but has to unplug the wires to get the jacks back up. This unit was working correctly, just not holding pressure. We had the pump checked out, and it is working fine.
