Electric
Scooter And Bike Troubleshooting Guide
Motor Runs But The Scooter
Does Not Move
- Check the power
transmission system. If the motor runs when the throttle
is applied but the rear wheel does not spin that points
towards a worn out rear wheel freewheel mechanism, or a
missing drive belt,
chain, or sprocket.
Motor Does
Not Run
- Test the battery or battery pack.
Test the Voltage level of the battery pack, it should be
above its rated Voltage level, even if it has been fully
discharged or in storage. If a battery packs Voltage
level does not bounce back to above its rated Voltage
level within a few minutes after the scooter has been
driven that points towards
a defective or worn out battery or battery pack. When a
battery or battery pack has been charged overnight and
its Voltage level is below its rated Voltage level that
also points towards
a defective or worn out battery pack. Good scooter battery
packs will bounce back to above their rated Voltage
level within a few minutes after being discharged.
| If the battery
or battery packs Voltage level does not bounce
back above its rated Voltage level within a few
minutes after the scooter has been driven that points towards
a defective or worn out battery or battery pack. |
- Test the battery
charger. Test the battery chargers output Voltage. Its
Voltage level should be above the battery packs rated
Voltage. If the chargers output Voltage level is zero or not above the battery packs rated Voltage that points
towards a bad charger.
- Test
the charger port. The charger
port should have the same Voltage level as the battery pack.
If the charger port has zero Voltage level that points toward
defective wiring or connectors between the charger port and the
battery or battery pack.
- Test the fuse or
circuit breaker. If
the fuse looks blown out or does not have continuity that points towards a blown out fuse. If the circuit breaker does not have continuity when
reset or will not reset that points towards a defective
circuit breaker.
- Test the brake lever
switch. The brake lever switch informs the speed
controller to turn off when the brakes are applied. When
this switch wears out it usually locks on which turns the
speed controller off. An easy way to test this switch is to
disconnect it from the speed controller and try to run the
scooter. If the brake lever switch is the problem the scooter will run
only when it is disconnected
-
Test the motor.
Remove the chain or belt from the
motor. Disconnect the motor wires from the speed controller
and connect them to a good 12 Volt battery. If the motor
spins freely then it is good. If the motor does not spin
that points towards a bad motor.
-
Test
the throttle. Testing a hall-effect throttle
requires a 4.3 Volt DC power source and a Voltmeter.
Apply 4.3 Volts DC positive to the throttles red wire
and 4.3 Volts DC ground to the throttles black wire.
Attach a Voltmeter between the black wire and the green
or blue wire and twist or push the throttle. The
Voltmeter should vary between zero and 3+ Volts. If the
throttle has zero or low output Voltage that points
towards a bad throttle.
-
Test
the power/key switch, wiring harness, and connectors.
Test the power
switch or key switch for proper operation and
continuity. Test the wiring harness and connectors to
make sure they are good.
| Speed
controllers problems can be difficult
to diagnose. Testing the other components of
the electrical system first is the easiest way to
see if the speed controller is working or
not. |
