There is a clue here, just don’t know exactly how it could be happening. Jim, Clarke or Guy may be able to help.

First, if the purpose of the Skinnners is to provided a backup to the Mac valves leaking, then the Mac valves that the Skinnners are attached to are definitely the DOWN valves. If wired and functioning correctly the only time those Skinners should be magnetized is if the Down switch is activated.

Second, can one of the owners of this vintage coach explain the basic layout and function of the switches?
Specifically, is there a switch that toggles between level and travel?
Does the ignition on, override that switch and force the system into travel?
Is there an ALL down or ALL up switch for lowering and raising the coach?

Never mind my questions, I found the picture you posted when noodling the mystery switch in the drivers compartment.

Ok, cranking up my Conspriatron 5000, is it possible that the ignition switch rewire and this issue are related. Did you ever notice this before the switch issue? If not, is it possible that during the ignition switch wiring that you either wired something incorrectly in the powering of the leveling system OR something wasn’t working (like the mystery switch) because it didn’t have power and now it does.
