Power gear hyd levelers low power

I don't know if yours is the same as mine, but their is a contactor with multiple electrical leads on them. Their totally exposed to the weather and corrosion, particularly if your in road salt country. You might try removing and cleaning each one to see if that makes a difference. But being as it's an 06, it might be time for a new pump.

Are you leveling your coach with the engine running? In addition your chassis battery might be low.

Yes, engine and gen running

Get to the pump. On the top of the pump system are solenoids. You will see a LARGE battery type cable to a large post on the Solenoid. THAT should have engine voltage(12.9 to 13.8 volts). If NOT, then you have a loose or corroded supply voltage from the batteries. IF you have Engine voltage, then have someone activate the system and READ the voltage on the other large post on the solenoid. This post has the cable from the solenoid to the Pump motor. IF you have the same voltage on both sides within 1/2 a volt, then you motor is bad. Good news is, Powergear pump motors can be rebuilt by a Starter/ Alternator local shop rebuilder. Doug

You may also want to make sure you have a good clean ground.

Have same issue: In my case the issue is NOT electrical as pump runs "Smartly" as the British might say (Same as new) but the pressure is not there. Replaced the suspect valve (Dump) still no joy... Now I have other issues that need fixing (need a hose shop with a portable crimper) then i'll drop in a new pump.

Bearings on the leveling motor go bad. If your reservoir and motor are behind the front grill water can get to the motor bearings. Mine started squealing, replaced the motor.

Mine is in a rear compartment
