1300
What This Code Means
Engine cranks and starts, then shuts down within about 5 to 10 seconds; Shutdown-Alarm Low Oil Pressure; External display board is not able to communicate with main board; Main board does not see communication from display board; Overcrank; Low to no fuel pressure while cranking; Overspeed (Over 72 Hz for three seconds); Throttle stuck open; Overspeed (Over 75 Hz for one second); Total loss of control; High temperature (Coolant temp greater than 246 ºF (119 ºC) for 1 second); Overcrank alarm; Overspeed (Over 72 Hz for three seconds with the throttle stuck open); Overspeed (Over 75 Hz for one second with the throttle stuck open, total loss of control); Low oil pressure while running; Controller Fault A; Overspeed (Instantaneous— Over 75 Hz for 1 second)
Possible Causes
- •Air Flow Impeded / Flow Issue
- •Air flow impeded
- •Broken stepper wire
- •Check the oil level
- •Controller issue
- •Controller run relay de-energizes and 12 VDC run circuit terminates
- •Defective oil pressure switch
- •Engine oil pressure drops below approximately 5 psi
- •Engine/Starter Problem
- •Faulty Wire 86
- •Flow issue
- •Internal Error
- •Internal Harness Loop Broken (internal to the display board)
- •Internal harness connecting external display board to main board has become disconnected
- •Internal harness loop broken (external display board)
- •Low engine oil level
- •Low oil level
- •Low oil level or low oil pressure
- •Low oil pressure
- •Low oil pressure condition
- •Low oil pressure or oil level issue
- •Low to no fuel pressure while cranking
- •No Fuel Pressure
- •Oil pressure switch contacts failed in closed position
- •Shorted harness
- •Stuck throttle
- •Switch contacts close connecting Wire 86 circuit to ground
Suggested Actions
- 1Because of the nature of cranking there is almost no insight into the cause of an overcrank alarm with the current sensors.
- 2Check Oil Pressure Switch and Wire 86
- 3Check coolant sensor circuit for proper operation
- 4Check coolant sensor circuit for proper operation.
- 5Check engine crankcase oil level and add recommended oil to the dipstick FULL mark if necessary (do not fill above full mark)
- 6Check for an intermittent oil pressure problem with a mechanical gauge if the input changed states successfully
- 7Check for intermittent oil pressure problem using a mechanical gauge
- 8Check oil level and pressure
- 9Check the inlet/outlet for debris
- 10Check the inlet/outlet for debris.
- 11Clear any faults in the controller before proceeding with any running diagnostic steps
- 12Clear any faults in the controller before proceeding with diagnostic steps
- 13Controller will reboot and transition to the same key state it was in before and resume operation.
- 14Fuel pressure has to be measured as low for at least 1200 ms before the overcrank alarm is set.
- 15Navigate to the Digital inputs display screen of the controller, set the controller to MANUAL, and observe Input 2 (Wire 86) for a change from '1' to '0'
- 16Navigate to the digital inputs display screen on the controller, set controller to MANUAL, and observe input 2 (wire 86) for a change from '1' to '0'
- 17Perform Test 61
- 18Replace controller if input changes states from '1' to '0' but generator still shuts down
- 19Replace the controller if the input changes states but the generator still shuts down
- 20Test 61
- 21Test 61 – Check oil pressure switch and Wire 86
- 22Test 61 – Check oil pressure switch and wire 86
