Im the new owner of a 78 coach that has a few wrinkles to work out. 
First up is the leveling system. I believe a pump is shot. It wont create pressure even though the piston is moving freely and the bore looks great. I swapped the heads and no change.
Finding a used one is pricey, and questionable to the length of time it will last. I'm curious if i can retrofit Viairs into it.
A couple of questions:
1) What is the function of the exhaust solenoid on the head of the pump? One harness reads 1 volt while pumping, and 12 when releasing air. The other reads 8v continuously, so there appears to be an issue there. Are these run off of the auto levelers?
2) The two center valves appear to really take care of the pressure release, so if those valves release pressure, why the exhaust valve on the compressor?
