What to do if my Generac Mobile MMG35DF4 has a low fuel level shutdown?
If your Generac Mobile Inverter experiences a low fuel level shutdown, here's what you should do: * Check the fuel level in the LCD window of the controller. * Confirm that the unit is level to ensure an accurate reading. * Check the fuel tank for any leaks. * Check for continuity between the sender and engine controller. Refer to the wiring diagrams for guidance.
How to fix a Generac Mobile MMG35DF4 high coolant temperature shutdown?
To address a high coolant temperature shutdown in your Generac Mobile Inverter: * Add coolant if the level is low. * Check the radiator shroud and ducting for any blockages and remove any foreign matter. * Inspect coolant hoses, engine block, and water pump for visible leaks. Also, check the tension of the water pump serpentine drive belt. Remove the load on the generator and restart the engine. Monitor the coolant temperature and immediately shut down the engine if it begins to overheat (230 degrees or higher). Consult the engine operator’s manual for more information on engine overheating.
What to do if my Generac Mobile Inverter shuts down due to low oil pressure?
If your Generac Mobile Inverter shuts down due to low oil pressure: * Check the oil level using the dipstick. * Inspect the engine visually for any oil leaks. * Restart the unit and verify the loss of pressure. If the pressure does not reach 5 psi (34 kPa) within five seconds, shut down the unit immediately. Refer to the engine operator’s manual to determine the necessary corrective action.
Why does my Generac Mobile MMG35DF4 shut down due to low coolant?
Your Generac Mobile Inverter might shut down due to a low coolant level. Here’s what to check: * Allow the engine to cool down, then check the coolant level in the radiator. * Inspect the coolant hoses for leaks, and repair or replace them if necessary. * Visually inspect the engine block and water pump for leaks. Also, verify that no coolant has mixed with the engine oil (which would appear milky). Refer to the engine operator’s manual for more information.
How to troubleshoot an overcrank shutdown on a Generac Mobile Inverter?
To troubleshoot an overcrank shutdown on your Generac Mobile Inverter: * Check the fuel level in the tank. * Check the fuel pump operation. * Check the air filter for any blockage. Consult the engine operator’s manual for further details.
What causes an overspeed or underspeed shutdown in a Generac Mobile MMG35DF4 Inverter?
An overspeed or underspeed shutdown in your Generac Mobile Inverter can be caused by an incorrect frequency setting. To resolve this: Disconnect all loads and restart the unit. Check the frequency (Hz) in the LCD window on the controller. It should read 60 Hz. If the frequency is above 60 Hz, the engine speed needs adjustment. Contact Isuzu to adjust the speed.
