Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on. | No power from outlet; loose connection; charger fault. | Check power outlet; ensure AC cord is fully plugged in; contact support if issue persists. |
| Charger not charging. | Incorrect battery connection; battery too deeply discharged (below 8.0V); incorrect mode selected. | Verify correct polarity (+ to + / - to -); ensure battery voltage is above 8.0V; select appropriate charging mode. |
| "ERR" or error code on display. | Reverse polarity; short circuit; overheat protection activated. | Check battery clamp connections; inspect cables for damage; allow charger to cool down. |
| Battery not fully charged after extended time. | Battery capacity too large for charger; battery is faulty or sulfated. | Ensure battery capacity is within 4-100Ah range; try REPAIR mode; consider professional battery testing. |
