Hello... I'm new to the forums and am hoping someone here is familiar with Genie lifts. I am working on a gas powered 4x4 lift. Two of the wheels are not driving. I have checked the main pump, some of the solenoid valves, electrical all seems good, have had the drive motors apart...seem ok. Have done the pressure tests on the two test ports one is fine the other is low, but can't figure out why. Any ideas would be greatly appreciated.

Thanks!
