4. Setup and Installation
The JingBo Intelligent Controller is designed for easy installation, but careful attention to wiring is crucial for proper function and safety. Refer to the wiring diagram provided with your specific motor and battery system for detailed connections.
4.1 General Wiring Guidelines
- Identify Main Power Cables: Connect the thick red cable to the positive (+) terminal of your 72V battery and the thick black cable to the negative (-) terminal. Ensure a secure connection.
- Motor Phase Wires: Connect the three motor phase wires (typically green, blue, yellow) from the controller to the corresponding wires on your brushless motor.
- Hall Sensor Wires: Connect the smaller Hall sensor wires (usually a bundle of five wires: red, black, yellow, green, blue) from the controller to the motor's Hall sensor port.
- Throttle Connection: Connect the throttle signal wire, power wire, and ground wire to the appropriate throttle input on the controller.
- Brake Levers: Connect the brake signal wires. The controller supports low-level brake signals.
- Ignition/Key Switch: Connect the ignition wire to your key switch or power button.
- Other Auxiliary Connections: Connect any additional features such as speed limit, reverse, cruise control, or anti-theft as per your system's requirements and the controller's specific wiring harness.

4.2 Mounting the Controller
Mount the controller in a secure location that is protected from direct water exposure and allows for adequate airflow to prevent overheating. Use appropriate fasteners to secure it firmly to the vehicle's frame.
5. Operating Instructions
Once the controller is correctly installed and all connections are verified, you can begin operation.
- Power On: Turn on the main power switch or key switch connected to the controller.
- Self-Learning (if applicable): Some controllers have a self-learning function to optimize motor parameters. Refer to your specific model's advanced features for this process.
- Throttle Control: Gently twist the throttle to engage the motor. The sine wave technology ensures a smooth and quiet acceleration.
- Braking: Apply the brake levers to activate the electronic braking function, which also cuts off motor power.
- Monitoring: Pay attention to any unusual noises, vibrations, or performance issues during operation.

7. Troubleshooting
If you encounter issues with your JingBo Intelligent Controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not running | No power, loose connections, faulty throttle, motor or Hall sensor issue. | Check battery charge, verify all wiring connections, test throttle, inspect motor and Hall sensors. |
| Motor runs intermittently or with jerks | Loose Hall sensor wires, incorrect phase wire connection, motor damage. | Ensure Hall sensor wires are secure, recheck phase wire connections, inspect motor for damage. |
| Controller overheating | Insufficient ventilation, excessive load, short circuit. | Improve airflow around controller, reduce load, check for short circuits in wiring. |
| No power to display/accessories | Loose accessory wiring, blown fuse (if applicable). | Check accessory connections, inspect and replace fuse if necessary. |
If the problem persists after attempting these solutions, it is recommended to consult a qualified technician or contact customer support.
