Anything is possible, but there is a difference in the way the pump sounds when loaded (he describes it as running against a closed valve), and a weak battery. Besides, he's my x boss: ham, TV and radio Chief, so I'm sure that was the 1st on the list. Having said that I'll call out there in a few and see if i need to bring crimpers, lugs, and/ or splices.

Doug: is there a common return for all those solenoids?

No, The 4 jacks all go thru the Shuttle valve extending and retracting. But, a failed/defective shuttle valve will only cause a problem on retract when there is NOT 3000 psi of pressure. The Slide rooms have their own solenoids (2 for each room). They do not interface with the Shuttle valve. A quick way to find if the shuttle vale is at fault on tha jacks is to crack the exit line loose from the valve and see if fluid squirts out when activating the pump.(messy). I would hook up a pressure gauge here and that would tell me if I had pressure. NOT messy:B I would think Quartzite would have someone there that works on HWH systems. Doug

The shuttle valve does interface with both the jacks and slides. The symptoms of a failed shuttle valve are jacks wont go all the way down, and slides that will go out some, and then not go back in. My shuttle valve failed yesterday as we were setting up. Since I had had this problem a few years ago, I knew the work around which is to take a cap off one of the tees that connects the hydraulic lines to one of the jacks(I took the cap off the drivers side rear jack). Then on the pump manifold there is a u-shaped pipe right above the jack solenoids about quarter inch in diameter. Disconnect the end on the right, and then loosen the other end,and then tip it out of the way, and put the cap that you took from the jack on it. Your slides will then work, but your jacks wont.

Hope this helps,
