Troubleshooting: Scooter Will Not Turn Off
Place the scooter off the ground so the rear wheel will not touch the ground.
You do not want your scooter to take off. Take the footplate off. Disconnect
the throttle clip under the footplate, then turn the scooter on and see if it still
runs. If it does, you will need a new controller.
Troubleshooting: Scooter On, But Will Not Move
Follow the wire from the left handbrake down under the foot plate. Unplug
this wire. There is a safety in that brake that will not allow the motor to run
when the brake is being applied. Make sure the rear wheel is off of the
ground, then try turning the throttle with this unplugged.
Troubleshooting: Is It My Throttle Or My Controller?
(These tests require a digital VOM)
Most E-scooter throttles use 'Hall-effect' devices, not potentiometers
(rheostats). A Hall-effect device is a chip that responds to a movable magnet.
If you have a digital VOM (I would not use an analog resistance meter of
any kind, as it could damage the chip if it's a Hall-effect chip), you can test
whether it's a potentiometer or not. If it is, you should get 5K ohms across
red and black, and of course, 0-5K from red or black to the third wire
(usually green or yellow). If it isn't, you'll get readings in the megohms in
one direction and no connection in the other in some cases.
A better test if you have a digital VOM, is to push the probes into the back of
the throttle connector at the controller while it is connected. Turn the scooter
on, and operate the throttle. You should get near zero to near 4 or 5 volts
between the black and third wire (green or yellow). These voltages work for
most scooters, but not all. Some throttles use 0-24 volts, and some use a
negative voltage (the throttle 'sinks' current).
You should also check the brake inhibit switch (there should be a wire cable
coming from your brake handle), to see if it is making and breaking
continuity. The brake inhibit switch turns the throttle off when you put the
