Fault diagnosis and maintenance
Motor abnormal noise
When troubleshooting the abnormal noise of the motor, please idle the motor first and confirm the source of the abnormal noise
again. After confirming the abnormal noise is from motor, proceed with the following procedure.
1. Check the motor bearings
Check whether the motor bearing lubrication operation is normal
NO
Replace bearing
YES
2. Check the inside of the motor
Check if there is foreign matter inside the motor?
YES
Clear foreign objects or replace the motor
The motor does not work
Before troubleshooting the motor does not work, please confirm whether the motor does not work because the side support is
not retracted (the side support switch is not closed). After confirming the elimination of the temple problem, proceed with the
following procedure.
1. Check the switch of parking switch
Turn off the power switch, and use the multimeter diode position to
check whether the P position switch is normal?
NO
switch of parking switch failure
YES
2. Check the brake power switch
Turn off the power switch, use a multimeter diode file to check
whether the brake power off switch is normal?
NO
Brake power switch failure
YES
3. Check the throttle grip
Confirm that the power supply voltage of the throttle grip is between
4.5-5.5V, use a multimeter DC voltage file to check whether the
signal line voltage of the speed-adjusting rotor is in the range of
0.8V-4.2V?
NO
Throttle grip failure
YES
4.Motor Hall
Check whether the motor Hall connector is in good contact?
NO
Motor Hall connector failure
YES
5.Confirm the motor Hall supply voltage
Confirm that the power supply voltage of the motor Hall is between
4.5-5.5V, and gently turn the motor by hand. Does the UVW Hall
wire change between high and low levels to ground?
NO
Motor Hall failure
YES
First replace the control to confirm whether the motor returns to
normal, if not, replace the motor.
