brakes on. It functions like a 'kill switch' should anything go wrong. You
should also test the key switch in the same way.
You can test the motor by jumping from the batteries to the motor, but be
aware that it will make a large spark, or you can test the voltage at the motor
connector while turning the rear wheel backwards. The motor should
generate a small negative voltage that varies with the speed it is turning.
A smell test is also conclusive proof that you have a damaged controller or
motor. If you can get your nose close to one or the other and it smells like
badly burnt broccoli, it's burnt out. Of course it could also be burnt out and
not smell, but if it smells it's burnt out.
Troubleshooting: Throttle Voltage Test
Follow throttle wires until you find its white connector. You will be testing
the “Red”, “Green”, and “Black” wires. Set your meter to test DC volts.
Block rear wheel off the ground so scooter will not take off. Turn the scooter
on. Place the red meter test lead on the “Red” wire and the black meter lead
on the “Black” wire. The meter should measure +5 volts. Now place the
meter red lead on the “Green” wire. With out turning the throttle you should
read around +0.8 volts. Now turn the throttle wide open. You should now
read 4 volts. If everything else powers up on the scooter and you do
not have +5 volts between the “Red” and “Black” wire the controller is bad.
If you did not get the +.8 to +4 volts then the throttle is bad.
Troubleshooting: Intermitted Power Loss
While doing each of the steps you are to go and test drive the scooter to
make it cutout like it was doing. You will need a voltmeter for electrical
readings and will also require a power cord that is used on a computer which
has the same type of plug that will plug into the charger port, with a wire
length of 2' and cut wire and discard the rest. What we are going to do is
attach the voltmeter leads to this computer wire and plug into the socket to
