Common problems

Starter engages-disengages (battery voltage dips below 6 volts while cranking—low battery charge, poor connections, long cables)
Cause: Battery voltage dips below 6 volts while cranking—low battery charge, poor connections, long cables
Fix: Clean and tighten the positive (+) and negative (-) battery cable connections at the battery and genset (Page 3-6); Recharge or replace the battery. Refer to the battery manufacturer's recommendations; Increase battery cable size or run parallel cables
Low oil pressure Low oil pressure-CODE NO. 2
Fix: Check the engine oil level and add or drain oil as necessary (p. 4-3). Repair any oil leaks.
UNDERVOLTAGE 13
Fix: Reduce the number of connected appliances, especially when air conditioners and battery chargers are running.
OVERVOLTAGE 12
Fix: See an authorized Onan dealer.
OVERCRANK 4
Fix: 1. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 2. Open any closed fuel valves. 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8).
LOSS OF RAW WATER FLOW 7
Fix: 1. Open the sea cock. 2. Close the sea cock and clean the sea water strainer. If the strainer is above the water line, fill it with water to assist priming. Secure the strainer cover and reopen the sea cock. 3. Reconnect or replace any disconnected or leaking raw water hoses (Page 19). 4. Remove any blockage from the strainer on the through-hull fitting on the bottom side of the hull. 5. Replace the raw water impeller (Page 23).
HIGH ENGINE TEMPERATURE 1
Fix: 1. Add coolant as necessary and repair leaks (Page 18). 2. Replace the engine thermostat, which might not be opening fully (Page 21). 3. Clean the raw water tubes in the heat exchanger, which might be clogged with scale (Page 22). 4. Flush the coolant system to remove coolant passage fouling (Page 18).
Actuator Overload 22
Cause: Load; Fuel supply; Intake restriction; Governor actuator operation
Fix: Check: Load; Fuel supply; Intake restriction; Governor actuator operation
OVERFREQUENCY 14
Fix: 1. If the line circuit breaker or any other circuit breaker has tripped, start the genset before resetting the breaker. (Frequency can overshoot when a circuit breaker trips under load.) If the genset continues to run, turn off or disconnect all loads, reset the breaker and bring the loads on one at a time without overloading the genset. 2. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 3. Prime the fuel system to remove air in the fuel lines (Page 8).
Governor Overload — Maximum allowable time at full-duty cycle was exceeded 22
Fix: Reduce the number of appliances running at the same time, especially those with high motor starting loads such as air conditioners; check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the generator set will run out of fuel before the propulsion engines.); remove combustion air or exhaust system blockages; check all fuel fittings for fuel and air leaks and tighten as necessary; replace fuel filters (p. 4-6); check for contaminated fuel by connecting to a source of known fuel quality
Field Overload — High field voltage induced by high rotor temperature or low power factor loads 38
Fix: Remove blockages to generator air flow at the front inlet air grill; reduce the number of appliances running at the same time, especially those with high motor starting loads, such as air conditioners; have air conditioners and other appliances checked for proper operation. (A locked compressor rotor can cause very low power factor.)
Field overload (High field voltage induced by high rotor temperature or low power factor loads) 38
Fix: Remove blockages to generator air flow at the front inlet air grill; Reduce the number of appliances running at the same time, especially those with high motor starting loads, such as air conditioners; Have air conditioners and other appliances checked for proper operation. (A locked compressor rotor can cause very low power factor.)

Procedures

Adjusting Frequency adjustment

Tools: Screwdriver

Remove access cover on left end of genset.
Find leads marked J8 HZ, 60 HZ and 50 HZ in wiring harness.
Connect 60 HZ or 50 HZ lead to J8 HZ as appropriate.
Secure access cover with four screws.

Adjusting High-Idle Speed adjustment

⚠ Keep your hands away from the engine belt and pulleys.

⚠ The actuator could overheat if the battery is left on more than 10 minutes.

⚠ Be prepared to clamp off supply and return fuel lines to stop the engine.

Tools: strobe or injector clamp-on tachometer, 12 volt battery, battery switch

Adjust the speed control lever stop.
Measure engine speed with a strobe or injector clamp-on type tachometer.
Remove the front and top access doors and loosen the front/left side panel assembly for access to the speed adjusting screw.
Disconnect the actuator leads and connect a 12 volt battery to the actuator terminals using a battery switch.
Switch the battery on, start the genset, measure engine speed (rpm) and stop the engine by switching off the battery.
Loosen the lock nuts on the two bottom screws and back out the clamping screw if speed is not between 3300 and 3400 rpm.
To increase speed turn the speed adjusting screw in 1 turn clockwise; to decrease turn it out 1 turn counterclockwise.
Repeat until high-idle speed is between 3300 and 3400 rpm and set the lock nut.
Run the clamping screw in by hand until snug, back it out 1-1/2 turns and set the lock nut.

Adjusting Speed Control Lever Stop adjustment

⚠ Accidental or remote starting can cause severe personal injury; disconnect the negative battery cable.

Remove the front and top access doors and loosen the front/left side panel assembly so it can swing left.
