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 discon-
nect 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
lights 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:
1.
Fixture or lens dirty. Clean reflective surface inside fixture and both inside and outside surface of glass lens.
2.
Bulb worn. Replace bulb due to normal use.
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. Perform transformer check as described above.
