I have a nite lite pro 2 and one of my lights is not turning on, replaced bulb and tested voltage @ the breaker. There are lights behind control panel. I ran back the wiring to a power board with a green light that was not lit but the other 3 are. Anyone have a clue ?
What voltage did you see at the breaker? Does your unit have LEDs or Halide bulbs? If LED have you checked the LED driver? If Halide have you checked the caps or ballasts?
Found a lot of times the pigtails off the light housings burn up, along with the receptacles in the junction box up on the mast.
