TABLE 5. TROUBLESHOOTING (CONT.)

Some genset service procedures present hazards that can result in severe per-

sonal injury or death. Only trained and experienced service personnel with knowledge of fuels,

electricity, and machinery hazards should perform genset service. See Safety Precautions.

WARNING

LOW CRANKING SPEED FAULT—CODE NO. 32

(Cranking speed less than 180 rpm for more than 2 seconds)

Corrective Action:

1. Clean and tighten the positive (+) and negative (−) battery cable connections at the battery and at

the genset.

2. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations.

3. Replace engine oil with oil of proper viscosity for ambient temperatures (Page 6). (High oil viscosity

can slow down cranking speed.)

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. Gasoline Models − Check and fill the fuel tank, as necessary. (Note: The genset fuel pickup tube

is probably higher up in the fuel tank than the vehicle engine pickup.)

2. Low Pressure LPG Models − Check and fill the LPG container, as necessary. On cold days the LPG

container may have to be kept at least half full to provide the rate of vaporization necessary to keep

up with the genset fuel demand.

3. High Pressure LPG Models − Check and fill the LPG container, as necessary, and drain the genset

LPG system of oil that may have migrated from the supply system (Item 5, Page 13). Make sure to

re-close the drain valve.

4. Secure the spark plug leads on the spark plugs (Page 20).

5. Replace the spark plugs (Page 20).

6. Service the air cleaner (Page 19).

7. Check for mechanical damage.

INVALID GENSET CONFIGURATION FAULT—CODE NO. 37

(Wrong frequency/rpm ratio)

Corrective Action: See an authorized Onan dealer.
