8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not turn on. | No power from outlet; loose connection; charger fault. | Check power outlet; ensure power cable is securely plugged in; verify battery clamps are correctly connected. |
| Charger displays "Fault" or error code. | Reverse polarity connection; short circuit; overvoltage/undervoltage; internal fault. | Check clamp connections for correct polarity; inspect cables for damage; ensure battery voltage is within range (12V); if problem persists, contact support. |
| Battery not charging or charging slowly. | Battery severely discharged/damaged; incorrect battery type; poor connection. | Ensure battery is a compatible 12V lead-acid type; check for clean and secure connections; try the pulse repair function for deeply discharged batteries. If battery is severely damaged, it may need replacement. |
