Important Considerations:
- Ensure the motor is a 36V 1000W brushed motor. This controller is not compatible with 3-phase motors.
- Match wire colors and connector types carefully. Incorrect wiring can damage the components.
- Secure all connections with appropriate electrical tape or heat shrink tubing to prevent short circuits and moisture ingress.
- Mount the controller in a location that allows for adequate airflow to utilize its heat dissipation fins.
5. Operating Instructions
Once the controller and throttle grip are correctly installed and connected, follow these steps to operate your electric vehicle:
- Power On: Insert the key into the throttle grip's lock and turn it to the 'ON' position. The battery display on the throttle grip should illuminate, indicating power is supplied to the system.
- Check Battery Level: Observe the battery display on the throttle grip to ensure sufficient charge before riding.
- Engage Throttle: Gently twist the throttle grip to accelerate. The speed will increase proportionally to how much the throttle is twisted.
- Braking: Apply the brakes as needed. The controller is designed to cut power to the motor when the brakes are engaged.
- Power Off: When finished, turn the key in the throttle grip to the 'OFF' position and remove it to secure the vehicle and conserve battery power.

- Inspect the power lock wiring for any disconnections.
- Motor Not Responding to Throttle:
- Confirm the throttle grip is properly connected to the controller.
- Check the motor connections to the controller.
- Ensure the motor is a compatible 36V 1000W brushed motor.
- Inconsistent Speed/Jerky Operation:
- Inspect all wiring for loose connections or damaged insulation.
- Check the battery charge level; low battery can cause inconsistent performance.
- Ensure the throttle mechanism moves smoothly without obstruction.
- Controller Overheating:
- Verify the controller is mounted in a well-ventilated area.
