Lights on joy stick controller blink on and off and chair wont move

Cezna Are the lights that are blimking the battery level lights or they the speed level lights. If it is the speed level lights then the chair thinks you still have the charger plugged in. If it is the battery level lights do a certain number of lights flash 3 lights flashing 4 lights flashes etc this is the flash code and will tell you what problem you have. It could also mean that you are in lockout or sleep mode If you have the VSI joystick then turn on the power immediately push the joystick forward and hold until you hear a beep then mmediately push it to the rear til you hear a beep then immediately let it return to the center position. If it was in sleep mode this should wake it up. Hope this helps you
