Went by Coach today to tinker with it some. It was still aired up high from yesterday so I went under the front and rear and looked at all the hcv's. They looked fine and with all the rods pulled down I knew if it went to travel mode it should lower. All the solenoids and wiring in the front looked fine. In the rear there is a terminal block labeled:
LU
LD
RU

M

The M has a wire cut about 2 inches long hooked there with the wires going to a solenoid. I hooked a longer wire to it since I figured to get it to travel mode it had to have 12v from the key go to something and this might be it. I touched it to 12 v and a solenoid clicked and it started lowering the suspension.. I unhooked it and started the engine to build air, made sure the leveling system was turned off and hooked the wire back to 12v. It went to travel mode and all the hcv's work like it's supposed to. Now I need to find the wire that is supposed to be there. Thanks again for all the information and I'll have other questions coming in other forums as I get this old classic going.
