Three fluorescent lights in my garage just stopped working. So here's the set-up: 2 switches, 3 fluorescent lights. Switch 1 has hot wire, travelers go to switch 2, switch 2 feeds all three lights. I am getting current to switch 1. I have changed out both switches, double and triple checked the way they are wired. I even put in a single pole at switch 1, and nutted the wires at switch 2 (tried each traveler pair) still no light. Checked all three lights to make sure connections in fixtures had not worked loose. Everything okay. What am I missing?
I'd have to go with the ballast of the first light (that switch 1 runs to) has died and needs replacement. However, tube-fluorescents have terrible socket connections and I've seen earthquakes, rumbling trucks, direct impacts and power surges kick them askew.
If you have tubes, then start with number 1 in just giving the bulbs a little twist to see if they pop on...yours may work in pairs-only, so you get one to flicker and then twist the other to get them both solid.
If so, then just do the same to the other 2 fixtures. If not, then a new ballast should remedy the situation.
