Welcome to the board. Ballasts is usually the last thing that goes on any type of fixture. I doubt the single leg switching will have anything to do with it unless the ballast or one of its leads were grounding out on something. Since the ballast replacement, how has the bulb life been since?
I do not mean any disrespect for asking the simplist questions, your posts has very limited info and I am well aware of wiring in churches.
Has the bulb been verified for proper mounting oriention?
Has all the connections been check to ensure good connections and proper wiring i.e. proper voltage tap?
Has the voltage at the fixture when the P.E. is closed been verified.
Has the capacitor been tested?
What it the open voltage at the socket?
How long is the run from the panel? What size wire is it that runs out to the light?
Has the been any adnormal power issuses in or around the Church?
To the best of your knowledge of the bulb/failure rate, is there any corralation with the failures with the weather? For example, When it rainy or adnormally hot, is there a higher rate of failures?
Is there any thing else on the circuit?
I would definently slave a relay off the P.E. to switch both legs. Someone cold get hurt.
details, details...
