7. Troubleshooting
If you encounter issues with your charger, refer to the following table for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No indicator lights. | No power from outlet; loose connection; damaged power cord. | Check the power outlet with another device. Ensure all connections are secure. Inspect the power cord for damage. |
| Charger connected but not charging (Red light not on). | Incorrect OBC bypass (for older Club Car models); battery deeply discharged or faulty; poor connection to golf cart. | Verify OBC bypass installation for compatible models. Ensure the 3-pin plug is fully inserted. Check battery voltage; if extremely low, a specialized recovery charge may be needed. |
| Charger not shutting off after extended charging. | Battery not reaching full charge; faulty battery; environmental factors (e.g., very cold temperatures). | Allow sufficient time for charging (up to 12-18 hours for a deeply discharged battery). Test battery voltage with a multimeter. Ensure charging in a suitable temperature range. If the issue persists, the battery may need replacement. |
| Charger gets excessively hot during operation. | Poor ventilation; internal fault. | Ensure the charger is in a well-ventilated area and not covered. If overheating continues, discontinue use and contact support. |
