TROUBLESHOOTING
DANGER!
HIGH VOLTAGE! DO NOT ATTEMPT TO TEST AND REPAIR GENERATOR AND
BALLAST ELECTRICAL SYSTEMS UNLESS YOU UNDERSTAND AND ARE QUALIFIED
TO WORK ON SUCH SYSTEMS.
!
SAFETY WARNING
When one lamp does not light, TURN OFF THE GENERATOR and test the lamp by switching
leads with a lamp that DOES light. DO NOT WEAR JEWELRY WHILE WORKING WITH
ELECTRICITY! If the following procedures do not solve your problem, have the circuit tested by a
licensed electrician. DO NOT attempt to test generator voltage or ballast electrical systems unless
you are a qualified electrician. Consult the factory for voltage specifications and test procedures
PROBLEM POSSIBLE CAUSE
1. Circuit breakers in the outlet box are not turned on or have tripped.
2. Lamps are not allowed time to cool after last being lit. You must
allow 15 minutes between the time the lights are shut off and the time
they are restarted.
3. The lam or lamps are burned out or broken.
4. One or more of the lamps are not screwed in securely.
5. Plug and socket at light bar not securely pushed together and
locked.
6. The temperature of the ballast is below –20 degrees F. the efficiency
of the capacitors in the ballast is not enough to ignite the lamps. For
operations where the temperatures of the ballasts falls below –20
degrees F. some means of warming the ballast must be used.
7. Low electrical system voltage.
8. A loose connection in the back of the lamp socket in the lamp holder.
9. A circuit breaker or breakers are defective.
10. A loose connection on the terminal board.
11. The engine and generator are not running up to speed (1800 RPM)
12. A wrong style replacement lamp (requiring a different ballast) has
been installed.
13. Too much power is being drawn from the auxiliary outlets.
14. Capacitor or transformer have failed.
ONE OR MORE LIGHTS
DO NOT LIGHT UP.
15. Corrosion has occurred on the lamp bases.
