Troubleshooting: Is It My Throttle Or 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 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.
