I just picked up a Grove AMZ66XT manlift. Everything works fine on it from the ground, but from the bucket, none of the joysticks work. The prior owner indicates that everything did work when it left his yard. What is functional are the foot pedal to raise engine RPM's, the Aux power button to raise engine rpms, the bucket tilt switch, the bucket rotate, and the front and rear axle steering controls.
I can't start or stop the engine from the bucket, nor can I move the machine, or extend/retract, or raise/lower the bucket.
Any early ideas? Is there a common hot for these controls maybe?
All assistance appreciated.
