No power to air dump valve

This is in regards to a 2000 Holiday Rambler Endeavor, with 3126 Caterpillar engine, power gear leveling system.

I have disconnected the wire off of the air dump valve and had someone push the air dump switch, with ignition in accessory position and the power turned on for the leveling jacks, and do not get a power reading on the wire.

The fuse is good, the ignition switch is turned to accessory position, the leveling system power button is pushed and the light is green on the power jacks leveling panel. I have popped the Carling switch out and tested for power on the switch, and one terminal shows power. and when the switch is pushed there is then one additional terminal showing power.

I suspect that somewhere along the line the system is not getting the signal that all criteria is met so it can activate the dump valve. ( ie: transmission in neutral, park brake on, etc.)

Does anyone have or know where to get a trouble shooting guide for this issue? Thanks, Gerald.
