Power steps acts crazy

Also check for bad grounds on wiring to controller.

Okie Dokie fellas. Thanks

first thought is lub the steps.

2nd make sure the batteries are fully charged.

I think JohnnyT hit the nail on the head. The motor controller monitors the amperage draw of the motor and shut it off when it gets to a certain level. If the stairs need lubrication the motor could be reaching the shut off amperage before they are fully extended.

The previous generation used limit switches. A lot of motors failed when the stairs either got rusty or hit an obsticle and wouldn't extend far enough to make the switch. The motor would continue to try to move them until it eventually burnt out. Now at least the motor shuts off before it burns out.

Gary, My experience has been that lubrication is often the cause of step reacting erratically. You might try a two step process of hitting all the joints with something like blaster then follow up with a quality lubrication... It might take more than one application.
