My Powerchair joystick controller flashes 9 light bars and will not move.
This is called a 9-light fault code, which means the joystick controller has detected that the freewheel lever(s) on one or both sides are not in the drive position (in gear). Confirm that each free-wheel lever (left and right) are in the drive position (one up, one down), locking both drive wheels. If your Powerchair is equipped with an on-board charger and the A/C cord is still connected to the Powerchair, a 9-light fault code will be activated. Consult your Powerchair User Manual for more information.
