Common problems

Mast Lights On But the Light Output is Low
Cause: Fixture and/or lens is dirty. Lamp worn due to normal use. Damaged or loose electrical connections. Generator output incorrect. Low transformer output
Fix: 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. Replace lamp. Check the mast coil cord, mast junction box and mast light connections.
Mast lights off but ballast indicators on control panel are on
Cause: 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.
Mast lights off and ballast indicators on control panel are off
Cause: 1. Check the connections inside the control box and inside each ballast box. 2. Generator output incorrect. Check the incoming voltage to the ballast by checking the available voltage on the duplex receptacle. Incoming voltage should be 120V +/- 5V. If voltage is incorrect, the engine speed may need to be adjusted or generator may require service. 3. 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.
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.
Restricted air filter
Fix: Inspect air filter for blockage.
Oil pressure switch failure
Fix: Refer to OEM engine operator’s manual to identify corrective action.
Oil leaking from engine
Cause: Visually inspect the engine for leaks.
Low transformer output
Fix: 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.
Low oil pressure shutdown
Cause: Low oil level
Fix: Verify oil level on dipstick. Add oil, if needed.
Leakage in coolant hoses, engine block, or water pump
Fix: Inspect
Generator output incorrect
Cause: Check the incoming voltage to the ballast by checking the available voltage on the GFCI receptacle. Incoming voltage should be 120V ±5V.
Fix: If voltage is incorrect, the engine speed may need to be adjusted or generator may require service.
Blockage in radiator
Fix: Inspect radiator shroud and ducting for blockage and remove any foreign matter.
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 2
Mast Lights Off, but Ballast Indicators on Control Panel are On.
Cause: Light fixture is too hot. Faulty lamp connection. Lamp broken
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.
