7. Troubleshooting
If you experience issues with your scooter's power or motor response, consider the following troubleshooting steps related to the controller:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scooter does not power on. | Disconnected battery, faulty ignition, or controller issue. | Check battery connection and charge. Inspect ignition switch. If these are fine, the controller may require professional diagnosis. |
| Motor not responding to throttle. | Loose throttle connection, faulty throttle, or controller malfunction. | Verify throttle wiring. Test throttle unit if possible. If issues persist, consult a technician. |
| Erratic acceleration/deceleration. | Loose motor phase wires, faulty Hall sensors, or internal controller fault. | Check motor wiring. This symptom often indicates a more complex internal issue with the controller or motor, requiring professional service. |
| Controller gets excessively hot. | Overload, short circuit, or internal component failure. | Immediately power off the scooter. Check for any obstructions to motor rotation. Seek professional inspection. |
For issues not listed or if solutions do not resolve the problem, contact a qualified electric scooter repair service.
