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 (Voltage, Ohms Multi-meter), 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 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:
Scooter Will Not Run
Scooter is turned on, speed and battery indicators are illuminated but the scooter will not
move.
X-Treme Electric scooters are manufactured with a safety device called a "Brake Kill
Switch". This devise cuts power to the motor whenever the hand brake is engaged. If the
brake kill switch is adjusted too tight, the speed indicator and battery indicator will
illuminate when the key is turned on but the scooter will not run when the hand throttle is
turned.
1. Check the adjustment setting of the brake kill switch.
a. Loosen the brake adjustment by turning the silver brake cable adjuster where the brake
handle and brake cable meet. If this did not fix the problem, proceed to step B.
b. Remove the battery cover and locate the set of wires coming from the controller (black
box with all the wires coming out) labeled "Brake". This is the brake kill switch. Disconnect
the brake kill switch from the controller by disconnecting un-clipping the wire connectors. If
