Troubleshooting

LTV

Lamp will not light

Lamp is too hot

Allow lamp to cool 10–15 minutes before 

restarting.

Faulty lamp connection

Check that lamp is tight in socket. Check 

connections inside connection boxes on 

light fixtures and tower.

Plug connection at fixture is loose or 

damaged

Repair or replace the plug connection.

Lamp broken or burned out

Check for:

■

broken arc tube or outer lamp jacket,

■

broken or loose components in lamp 

envelope,

■

or blackening or deposits inside lamp 

tube.

Circuit breaker turned on

Turn off circuit breaker.

Circuit breaker loose or faulty

Repair or replace the circuit breaker.

Generator output incorrect

Check incoming voltage to ballast. 

Incoming voltage should be 120V ± 5V. If 

voltage is incorrect, engine speed may 

need to be adjusted or generator may 

require service.

Low or no ballast output 

With the fixture cord removed from its 

receptacle, the voltage should measure 

400 to 445 VAC. If proper voltage is not 

achieved, perform capacitor check to 

determine if capacitor or coil needs to be 

replaced.

Low light output

Lamp degraded

Replace lamp due to normal lamp life.

Low ballast output

Check ballast for proper voltage output.

Fixture or lens dirty

Clean reflective surface inside fixture and 

both inside and outside surface of glass 

lens.
