TABLE 4. TROUBLESHOOTING (CONT.)
Some genset service procedures present hazards that can result in severe per-
sonal injury or death. Only qualified service personnel with knowledge of fuels, electricity, and
machinery hazards should perform genset service. See Safety Precautions.
WARNING
HIGH TEMPERATURE—FAULT CODE NO. 1
(Engine coolant or inverter heat sink temperature exceeded design limit)
Corrective Action: Check the second-level fault code by touching Stop. The second-level fault will be
either No. 33 or No. 34.
LOW OIL PRESSURE—FAULT CODE NO. 2
(Low oil pressure cutoff switch did not open)
Corrective Action:
1. Check engine oil level and add oil as necessary (Page 15).
2. Drain excess oil (above dipstick Full mark).
SERVICE CHECK FAULT—CODE NO. 3
(A second-level fault occurred)
Corrective Action: Check the second-level fault code by touching Stop. The second-level fault will be
one of the following in this table.
OVERLOAD—CODE NO. 8
(Models HDKAH & HDKAV only: Load exceeded110 percent of genset rating for 2 minutes)
Corrective Action: Reduce load and restart
OVERCURRENT FAULT—CODE NO. 11
(AC output short)
Corrective Action:
1. Turn off the genset line circuit breaker. If the genset no longer shuts down, the genset is probably
okay—check for and repair a short circuit in the vehicle appliances, wiring or shorted battery charger
transformer.
2. Check whether the vehicle engine and genset share the same starting battery. If so, and this fault
occurs when cranking the vehicle engine, low battery voltage may be causing this shutdown. In-
crease battery capacity or install a separate battery and battery charging system for the genset.
