Jack system won't dump air-Powergear

[shipicker]

Well, here I am again, hat in hand, trying to find another problem. This one is by far the most difficult yet. My jacks stopped working a few months ago, and I and others, have not been able to find the problem. The system will not dump the air so that the jacks can come down. I have had the master dump valve removed and checked, installed another valve, which made no difference, replaced the two front leveling valves which were leaking but have no relativity to this problem, replaced the touchpad on the dash to no avail, redid the ground wire of the system, checked all of the wiring in the back by the leveling solenoids, replaced the solenoids, and now still nothing.
A diesel mechanic jumped the valve from underneath, and she set down like it should. But it will not work at all as it should. Right now I'm backing up on oak boards, and hate it!
Any ideas?

"Jumped the valve from underneath". You are going to have to check the continuity of everything upstream. Each wire, each switch. Maybe run wire back to the battery with a switch to bypass problem area?

This morning ? If so it's only 8:29. I've been dealing with them for years and give out their email address often. Did you use the address I posted ?
