OK Jon I'll try that, I sure wish I had an extra coil and valve on hand.

Yes, I have verified that the right and left rear raise and lower as they are supposed to I have done it several times. So I will use one of those solenoids for in place of the top one. One question, is the auxiliary tank the little pancake tank in the compartment under the seat? If so how do I turn off the aux pump to keep it from trying to refill if I have to replace the valve. My pump for that tank is a 12 volt pump at the back of the generator.
That's a Marathon question I cannot answer. I presume you can turn off the aux pump and bleed the aux air system down to zero if you have to change the valve and not just the coil. On my coach I have a connection for an air hose in that compartment as well as drain cocks on my pressure regulator bowl so I can dump air in the aux system at either place.
If all you change is the coil that has no impact on air pressure. Unless the Marathon suspension system is different than the Prevost Level Low (apart from HWH) dumping aux air will not change the height of the bus as long as the key is off, but anytime you are working on any part of the bus, either keep your body and all its parts out from beneath the bus, or support the chassis so it cannot drop.
you can turn that air compressor off at the small round circuit breaker back in the bedroom behind the dark plastic door. Look for the one marked aux air and push it, it should pop out, thats off.

Jon, thanks for all your help it has been raining here today so haven't gotten back to it, I'll see what the weather man serves up tomorrow.
Kevin, I have one that is labeled air compressor but when I push on the small round circuit breakers they don't pop out. It would seem that they should do something in order to turn off a circuit.
Push it harder. It will pop out.
