My Powerchair joystick controller just flashes lights when I turn it on.
This occurs when the joystick controller detects a problem in the Powerchair and oftentimes, but not always, a steady warning beep will sound in conjunction with the flashing lights. Each number of light bars that flash (1 through 10) represents a different fault code which helps locate where the problem has occurred. DO NOT drive the Powerchair if a fault code is present. Consult your Powerchair User Manual for more information
