The Pride GoGo 4 wheel scooter does not move forward or backward. when the key is turned on the batery meter displays a full charge. When the forward or reverse lever is pressed the unit beaps numerous times but does not move.

Hi. How many beeps between pauses? This is a fault code.
A couple of problems might cause this fault. Is your free-wheel lever in the correct place. These levers operate a switch, that tells the controller that the brake is disabled, this stops the controller from driving the scooter with out brakes.

Might also be caused by a stuck brush in the motor. This is usually caused by the caps that hold the brushes in, not being tight enough. Check the brushes, make sure they slide in and out smoothly, retighten the caps. Be carefull because these caps can crack easily.
Good luck. Neil.
