Problem: Motor Runs Constantly
(Runaway Scooter) |
First Step: Test Throttle and Speed Controller |
Most of the time when an electric scooter's
motor runs constantly it is due to a faulty speed controller. However on occasion it may also be caused by a
faulty throttle or a short circuit in the throttle cable
wires.
To test whether the problem is the throttle or the speed controller
simply disconnect the throttle from the speed controller. The throttle to
speed controller connector is usually located near the speed controller. If the motor stops running
continually with the throttle disconnected then the throttle is faulty. If the motor still runs continually
with the throttle disconnected then the speed controller is faulty.
Replace the faulty component and then retest the
scooter. |
