| Symptom | Cause | Remedy |
|---|---|---|
| Electrical Shock When Frame Is Touched | Static charge | Ground unit frame at local reference ground. |
| Engine Cranks But Will Not Start | Refer to engine manual or contact Generac Mobile Products Technical Service. | |
| Engine Overheats | Refer to engine manual or contact Generac Mobile Products Technical Service. | |
| Engine Starts But Will Not Run Smoothly | Refer to engine manual or contact Generac Mobile Products Technical Service. | |
| Engine Will Not Crank (Electric Start) | Refer to engine manual or contact Generac Mobile Products Technical Service. | |
| High Coolant Temperature Shutdown | Low coolant level | Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Restart engine and check coolant temperature (on controller). Stop engine immediately if coolant temperature is 210°F (99°C) or more. |
| High Output Voltage | Excessive speed | Verify engine RPM.; Check AVR adjustment. |
| Low Coolant Level Shutdown | Low coolant level | Allow engine to cool, then check coolant level in radiator. Add coolant, if needed. |
| Low Fuel Level Shutdown | Low fuel level | Check fuel level in LCD window of controller. |
| Low Oil Pressure Shutdown | Low oil level | Check oil level on dipstick. Add oil, if needed. |
| Low Output Voltage | Incorrect speed | Verify engine RPM.; Check AVR adjustment. |
| Mechanical Noise | Internal failure of alternator | Contact Generac Mobile Products Technical Service. |
| No Output Voltage | Circuit breaker tripped or failed | Reset or replace circuit breaker. |
| Overcrank Shutdown | Fuel level low | Check fuel level in tank.; Check fuel pump operation.; Check air filter for blockage.; Refer to engine operator’s manual for additional information. |
| Overspeed or Underspeed Shutdown | Frequency setting incorrect | Disconnect all loads and restart unit. Read frequency (Hz) in the LCD window on controller. Frequency should read 60 Hz.; If frequency is above 60 Hz, engine speed will need to be adjusted. Refer to the engine operator’s manual for throttle adjustment information. |
