Hydraulic Levelers Inop

[Hooter G]

2008 Cayman PDQ with Power Gear hydraulic levelers. Parked in a remote area. Tried to use the auto levelling feature but apparently the front end was too high and the rear jacks could not extend far enough to get front-to-back level. Pump made a high-pitch sound and I shut the system down. The right jack was at the end of its travel. I retracted all jacks and they came up as usual.

When I tried to use the system again jacks will not deploy automatically or manually. I have power to the control panel and have checked the fuses. Since the jacks retracted okay I think the controls are okay.

Have I burned up the pump motor? Is there a circuit breaker that I'm missing?

Any suggestions?

Thanks,

your setup should be the same as mine. the pump and reservior will be behind the "grilled door" right behind the left rear wheel.

there is a horizontal reservior, a motor, a large solenoid, and a fluid manifold with 3 or 4 solenoid operated valves on it.

I'd start by putting the system in manual, and having someone hit some jack buttons while I had my head in there listening to the solenoids.

Any button pushed should energizes the big solenoid and turn on the motor.
Also, the appropriate fluid valve should go. u probably can't hear these.

possible the fuse for the motor solenoid blew, it will be in the front drivers bay.
I'm not sure about a fuse for the motor itself. The pace arrow I had to rebuild the jacks on didn't have one, wired straight from the chassis battery to the solenoid to the motor. I haven't looked on the knight, jacks always worked good (knock on wood)
