Troubleshooting the Lights
IMPORTANT NOTE: Only a qualified electrician
should troubleshoot or repair electrical problems
occurring in this equipment. Contact Generac Mobile
Products Technical Service at 1-800-926-9768 for
assistance if you have any questions, or if problems
persist.

WARNING
Burn hazard. Lamps become extremely hot
while in use. Allow 10–15 minutes for cooling
before handling or lowering mast. Touching a
hot lens or fixture can cause severe burns.
(000187)
WARNING
Electrocution. Potentially lethal voltages are generated
by this equipment. Render the equipment safe before
attempting repairs or maintenance. Failure to do so
could result in death or serious injury.
Problem
Possible Cause
Solution
Mast Lights Off,
Checking Outside the
Control Box
Light fixture is too hot.
Faulty lamp connection.
Lamp broken.
Loose lighting connections.
Damaged or loose
electrical cord.
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
Control Panel Are Off
Loose lighting connections.
Generator output incorrect.
Low transformer output.
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.
Mast Lights On But the
Light Output is Low
Fixture and/or lens is dirty.
Lamp worn due to normal
use.
Damaged or loose
electrical connections.
Generator output incorrect.
Low transformer output.
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.
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.
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.
One or more lights do not
turn on
Light breaker tripped.
Lights not turned on.
Check light breakers.
Check electronic control to see if lights are on.
Turn lights on.
