Motor Controller Troubleshooting
1. Make sure there is Power present on the Motor Controller unit.
L2 should be ON, if not ON, check to see if the power cable is
properly connected to the unit. If still no power to the unit,
please check resistances between the following terminals. If any
resistance fails, the motor controller is faulty.
a. GND and POWER
Very High ~ M ohms
b. GND and MOTOR +
Very High
c. GND and MOTOR -
Very High
d. POWER and MOTOR +
Very High
e. POWER and MOTOR -
Very High
2. Make sure the unit is communicating with the main controller
(refer to the Blink Codes). L7 and LED1 on the motor controller
should be blinking at high frequency. If not, check wiring
between J12 of the motor controller to the main controller.
Check fuse on the motor controller.
3. Make sure the brake is ok.
a. L5 on the Motor Controller is ON and L6 is OFF. If L5 is
OFF, it means that the brake's manual override system is
activated. In such case, the motor controller will not drive
the motor. Manual override lever situated on the brake
should be disengaged in order for the motor controller to
drive the motor.
4. L6 should only turn ON when the joystick is moved either forward
or reverse. If L6 remains ON or OFF regardless of the position
of the joystick, the motor controller may be faulty.
