Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger won't turn on | Power issue, blown fuse, faulty outlet | Check power supply, replace fuse if needed, test outlet |
| No charging output | Loose connections, faulty clamps, wheel not engaged | Check all connections, ensure wheel is properly engaged |
| Overheating | Insufficient ventilation, high ambient temperature | Move to cooler area, ensure proper airflow around unit |
| Wheel slipping | Worn drive mechanism, improper tension | Adjust tension spring, inspect drive components |
| Inaccurate readings | Faulty meter, calibration needed | Recalibrate according to manual, check battery voltage separately |
| Spark when connecting | Charger turned on during connection, battery load | Always connect clamps with charger off, then turn on |
