| Symptom | Cause | Remedy |
|---|---|---|
| AC Circuit Breaker OFF | There is a short circuit or a significant overload at the receptacles, or if the ground fault circuit interrupter (GFCI) detects a ground fault current. | Reset the AC circuit protector ON. |

| Even when oil is added to the engine, the generator will not restart until the Oil Alert indicator is reset. | Turn the engine switch to the OFF position, add the proper amount of oil (see page 49), and then turn the engine switch back to the ON position. | |
| GFCI System ① will shut off power to all receptacles, including GFCI system ② and AC Circuit Breaker | If there is a ground-fault current from either A, B or C receptacle. | |
| GFCI System ② will shut off the power to that 120 V 20 A DUPLEX RECEPTACLE | If there is a ground-fault current from either 120 V 20 A DUPLEX RECEPTACLE. | |
| OIL ALERT INDICATOR comes on when you turn the engine switch to the START position | Check the engine oil level (see page 48) before troubleshooting in other areas. | |
| The Oil Alert indicator will illuminate. | Check the engine oil level (see page 48) before troubleshooting in other areas.
