One error code shows up on rare occasions. # 12 Low voltage to steer sensor I think.....

This unit during normal use even at full charge seems to get confused on how to control the operation of each drive motor. While driving straight on motor might decide to stop all together or start turning in a rev. direction as if it was being steered fully in one direction. The back up alarm does go off some times, evvvven though the direction is in FWD.

Steer POT. was replace and the problem did go away for a month or so.

The problem shows up mostly while going up a ramp in the warehouse.

Battery and charger have been fully inspected with no faults found.

Anyone seen this or have any ideas?

Cheers
