unlock the lock tab one of the good pins. And pull the wire out of the controller and reconnect the
connector. Tape off the gold pin so you can protect it. Return to above instructions above.
Troubleshooting: Scooter Won’t Run, Charger Light Stays Green
When you plug your charger into your scooter and the wall outlet the charger light stays green.
This is telling me that somewhere between charger socket, controller, fuse holder and batteries you
have an open circuit. Please remove the floor plate and check the wires in this area. You may find
a wire that is not connected, a connector that is not pushed together properly or a fuse holder that
is not letting the fuse connect properly.

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).
