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 INVERTER TEMPERATURE FAULT—CODE NO. 34
(Inverter heat sink temperature exceeded design limit*)
Corrective Action:
1. Check for and remove any objects blocking the air inlet or outlet openings in the bottom of the genset.
2. Reduce the number of appliances connected at the same time. (Note that high altitude and high am-
bient temperature decrease cooling capacity.)
CONTROL CARD FAILURE FAULT—CODE NO. 35
(Microprocessor EEPROM error during self-test)
Corrective Action: See an authorized Onan dealer.
ENGINE STOPPED FAULT—CODE NO. 36
(Engine stopped without command by controller)
Corrective Action:
1. Check fuel level. (Note: The genset fuel pickup is probably higher than the vehicle engine pickup.)
2. Prime the engine fuel system by holding the control switch down in its Stop position for at least 1 min-
ute.
3. Check the engine air filter and remove any blockage (Page 17).
4. Check for mechanical damage.
INVALID GENSET CONFIGURATION FAULT—CODE NO. 37
(Genset configuration is preprogrammed at the factory)
Corrective Action: See an authorized Onan dealer.
OVERCURRENT FAULT—CODE NO. 38
(Too many loads connected)
Corrective Action: Reduce the number of appliances running at the same time, especially those with
high motor starting loads such as air conditioners. Start up with no load and let the genset run for five
minutes to cool down the inverter.
PROCESSOR FAULT—CODE NO. 42
(Microprocessor ROM error during self-test)
Corrective Action: See an authorized Onan dealer.
