Common problems

WrnMaintenance — The period for servicing is set by the WrnMaintenance setpoint; the protection comes active if the running hours of the engine reach this value
Cause: Running hours of the engine reach the WrnMaintenance setpoint
Fix: Reset the "ServiceTime" reminder to the 250 hour interval
Wrn RA15 fail — Warning alarm in case of lost connection to IGL=RA15 module
Cause: Lost connection to IGL=RA15 module
Very high soot load warning SPN:3719.16
Very high soot load - needs service SPN:3719.00
TimingSensor SPN:637
PositionSensor SPN:636
Overspeed or underspeed shut down
Cause: Engine speed above or below 60.0 Hz
Fix: Disconnect all loads and restart the generator, read the frequency (Hz) on the LCD display (with no loads the frequency should read 60.0 Hz); if the frequency is above or below 60.0 Hz, adjust the engine speed per the engine manual for throttle adjustments on mechanical governed units and the electronic governor manual for electronically controlled units
Overcrank shut down
Cause: Low fuel level in the tank; fuel pump not operating properly; air filter blockage; engine will not start
Fix: Check the fuel level in the tank; check for proper operation of the fuel pump; check air filter for blockage; if the engine will not start, consult the engine operation and maintenance manual for additional information on troubleshooting starting problems
Low oil pressure shutdown
Cause: Low engine oil level; oil leaks; loss of oil pressure; oil pressure sender fault
Fix: Check the level of the engine oil with the dipstick and add oil if required; visually inspect the engine for oil leaks; restart the unit and verify the loss of oil pressure, shutting the engine down immediately if the oil pressure value does not read 5 psi (34kPa) within 5 seconds; check the oil pressure sender and refer to the troubleshooting section of the engine operation and maintenance manual
Low fuel level shut down
Cause: Fuel level low; leaks in the fuel tank; fuel level sender and connecting wiring damaged
Fix: Check the fuel level on the LCD window and confirm the generator is sitting level; check for leaks in the fuel tank; check the fuel level sender and the connecting wiring for damage and check for continuity between the sender and the engine controller
Low coolant level shut down
Cause: Low coolant level; visible leaks in coolant hoses, engine block or water pump; coolant mixed with engine oil
Fix: Allow the engine to cool; check the coolant level in the radiator and add coolant until it is 3/4 in (2 cm) below the filler neck; inspect coolant hoses, engine block and water pump for visible leaks; check the engine oil to verify no coolant has mixed with it and consult the engine operation and maintenance manual

Procedures

Checking Generator Drive Plate Torque maintenance

Disconnect the engine starting battery
Remove the generator fan guard
Torque each of the drive plate bolts to the specification (MMG330: 33 ft-lb / 45 Nm)
Reinstall the generator fan guard and reconnect the battery

Resetting of the Time to Service Reminder maintenance

With the unit shut down, power up the controller with the Control On/Off toggle switch
Press Page Select until Engine Protect line is reached and press Enter
"WrnMaintanance" appears with the current service time hour setting below it
Press Enter; current run time in hours appears on the display
Reset the current run time hour setting to 250
Press Enter to save the run time hour setting
Move the Control On/I toggle switch to Control Off/O

Towing the Trailer / Wheel Lug Torque Sequence maintenance

Start all lug nuts by hand
First pass: tighten to 20-25 ft-lbs (27-33 Nm)
Second pass: tighten to 50-60 ft-lbs (67-81 Nm)
Third pass: tighten to 90-120 ft-lbs (122-162 Nm)
After the first road use, re-torque the lug nuts in sequence
