hydraulic leveling jack for class A

I don't know why they wouldn't retract, because you are manually opening the valves, and the springs retract them.

I loose all power to my jacks and slide quite often. I gave up on trying to find the intermittent connection, and just wired around it thru a switch under the hood, which not only brings 12v power directly to the pump sillynoid, it also bypasses every saftey device, parking brake, etc etc.

Moved from General RV'ing forum.

sounds like a short in the control panel.

Check and see hat make the jacks are. Should be HWH.
Go to there web site. Check there trouble shooting page. I you can also contact them for the right answer.
