This Terex, amida, light plant (tower), will run for about half an hour then all four lights go out at once, but the motor keeps running. Bulbs are good. Not sure where to look. Circuit breaker not tripped. Any help will be greatly appreciated.
Do you still have power out of the receps when it happens?
Yes.
What do you do to get them on again? I would suspect the ballasts are shot. For the cost of a new ballast and bulb you can upgrade to LED's
Shut it off and let it cool down. Each light has it's own breaker so I am thinking that if it was a ballast they all 4 wouldn't go out at the same time. Does not trip the breakers. Let it cool down, same scenario.
