Common problems

Overspeed or Underspeed Shutdown
Cause: Frequency setting incorrect
Fix: Disconnect all loads and restart unit. Read frequency (Hz) in the LCD window on controller. Frequency should read 60 Hz. If frequency is above 60 Hz, engine speed will need to be adjusted. Refer to the engine operator’s manual for throttle adjustment information.
Low oil pressure shutdown (000139)
Cause: Low oil level
Fix: Verify oil level on dipstick. Add oil, if needed.
High coolant temperature shutdown
Cause: Low coolant level
Fix: Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Restart engine and check coolant temperature. Stop engine immediately if coolant temperature is 210°F (99°C) or more.
Unit cranks, but will not start
Cause: Fuel level low
Fix: Check fuel level in tank. Verify fuel pump operation.
Oil leaking from engine
Cause: Visually inspect the engine for leaks.
Mast lights on but the light output is low
Fix: 1. Fixture or lens are dirty. Clean reflective surface inside fixture and both inside and outside surface of glass lens. Use mild soap and water to clean lens. Other chemicals may have an adverse effect on the glass. 2. Bulb worn due to normal use. Replace bulb. 3. Check the mast coil cord, mast junction box and mast light connections. 4. Generator output incorrect. Check the incoming voltage to the ballast. Incoming voltage should be 120V +/- 5V. If voltage is incorrect, engine speed may need to be adjusted or generator may require service. 5. Low transformer output. The voltage from the transformer should read approximately 400 VAC as the light “strikes” (induces an arc), then drop and slowly rise back up to stabilize at 240-260 VAC. On quick disconnect models, measure across the junction box terminals when the light is unplugged. On hard wired models, remove the mast junction box cover and insert the wire probes into the connector blocks for the light and ground. If proper voltage is not achieved, perform capacitor check to determine if the capacitor or coil needs to be replaced.
Mast lights off but ballast indicators on control panel are on
Fix: 1. Mast light is too hot. Allow light to cool 10-15 minutes before restarting. 2. Faulty bulb connection. Check that the bulb is tight in the socket. 3. Bulb broken. Check for broken arc tube or outer bulb jacket, broken or loose components in bulb envelope or blackening/deposits inside tube. 4. Check the connections inside the mast junction box and each mast light housing/socket. 5. Check the mast electrical cord for damage and check the cord connections inside the control box.
Leakage in coolant hoses, engine block, or water pump
Fix: Inspect for visible leaks. Verify tension of water pump serpentine drive belt.
Blockage in radiator
Fix: Inspect radiator shroud and ducting for blockage and remove any foreign matter.
Restricted air filter
Fix: Inspect air filter for blockage. Refer to OEM engine operator’s manual for additional information.
OVERCRANK SHUTDOWN
Fix: 1. Check the fuel level in the tank. 2. Check for proper operation of the fuel pump. 3. Check the air filter for blockage. 4. If the engine will not start, refer to the engine operator’s manual for additional information on trouble-shooting starting problems.
Oil pressure switch failure
Fix: Refer to OEM engine operator’s manual to identify corrective action.
Mast lights on but the light output is low.
Fix: 1. Fixture and/or lens is dirty. Clean reflective surface inside fixture and both inside and outside surface of glass lens. Use mild soap and water to clean lens. Other chemicals may have an adverse effect on the glass. 2. Bulb worn due to normal use. Replace bulb. 3. Check the mast coil cord, mast junction box and mast light connections. 4. Generator output incorrect. Check the incoming voltage to the ballast. Incoming voltage should be 120V +/- 5V. If the voltage is incorrect, the engine speed may need to be adjusted or the generator may require service. 5. Low transformer output. The voltage from the transformer should read approximately 400VAC as the light 'strikes' (induces an arc), then drop and slowly rise back up to stabilize at 240-260VAC. On quick disconnect models, measure across the junction box terminals when the light is unplugged. On hard wired models, remove the mast junction box cover and insert the wire probes into the connector blocks for the light and ground. If proper voltage is not achieved, perform capacitor check to determine if the capacitor or coil needs to be replaced.
Mast Lights Off, but Ballast Indicators on Control Panel are On.
Cause: Light fixture is too hot. Faulty lamp connection. Lamp broken. Loose lighting connections. Damaged or loose electrical cord
Fix: Allow light to cool 10-15 minutes before restarting. Check that the lamp is tight in the socket. Check for broken arc tube or outer lamp jacket, broken or loose components in lamp envelope, or blackening/deposits inside tube. Check the connections inside the mast junction box and each mast light housing/socket. Check the mast electrical cord for damage and check the cord connections inside the control box.
Mast Lights Off, and Ballast Indicators on the Control Panel are Off.
Cause: Loose lighting connections. Generator output incorrect. Low transformer output.
Fix: Check the connections inside the control box and inside each ballast box. Check the incoming voltage to the ballast by checking the available voltage on the GFCI receptacle. Incoming voltage should be 120V +/- 5V. If voltage is incorrect, the engine speed may need to be adjusted or generator may require service. The voltage from the transformer should read approximately 400VAC as the light 'strikes' (induces an arc), then drop and slowly rise back up to stabilize at 240-260VAC. On hard wired models, remove the mast junction box cover and insert the wire probes into the connector blocks for the light and ground. If proper voltage is not achieved, perform capacitor check to determine if the capacitor or coil needs to be replaced.
