Troubleshooting and error codes
| PROBLEM | POSSIBLE CAUSE | SOLUTION |
|---|---|---|
| Charger will not turn on when properly connected. | AC outlet is dead. | Check for open fuse or circuit breaker supplying AC outlet. |
| Charger will not turn on when properly connected. | Poor electrical connection. | Check power cord and extension cord for loose fitting plug. |
| Engine start does not work. | Drawing more than the Engine Start rate. | Crank time varies with the amount of current drawn. If cranking draws more than the Engine Start rate, crank time may be less than 5 seconds. |
| Engine start does not work. | Failure to wait 3 minutes (180 seconds) between cranks. | When the Engine Start LED blinks, wait 3 minutes of rest time before the next crank. |
| Engine start does not work. | The charger may be overheated. | The thermal protector may have tripped and needs a little longer to reset. Make sure the charger vents are not blocked. Wait and try again. |
| Engine start does not work. | Battery may be severely discharged. | On a severely discharged battery, use the Boost rate for 10 to 15 minutes, to help assist in cranking. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The battery voltage is still under 10V (for a 12V battery) or 5V (for a 6V battery) after 2 hours of charging. | The battery could be bad. Have it checked or replaced. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The charger cannot desulfate the battery. | The battery could not be desulfated; have it checked or replaced. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The battery was unable to reach the "full charge" voltage. | May be caused by trying to charge a large battery or bank of batteries on too low of a current setting. Try again with a higher current setting or have the battery checked or replaced. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The charger was unable to keep the battery fully charged in maintain mode. | The battery won't hold a charge. May be caused by a drain on the battery or the battery could be bad. Make sure there are no loads on the battery. If there are remove them. If there are none, have the battery checked or replaced. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The charger detected that the battery may be getting too hot (thermal runaway). | The charger automatically shuts the current off if it detects the battery may be getting too hot. Have the battery checked or replaced. |
| The red Clamps Reversed/ Bad Battery LED is lit. | The battery voltage dropped too low during the maintain mode. | May be caused by a drain on the battery or the battery could be bad. Make sure there are no loads on the battery. If there are remove them. If there are none, have the battery checked or replaced. |
