Re: ballasts





Yellows on one side, one lamp to reds and another if present to blues on
the
other sides. 120 vac. I checked voltages except the actual drive, supposed
to be about 380 vac unloaded. I will measure that next. I had to defeat
contacts to get access. Its all in a big hood. It worked, now it still
does ot
even with new parts. I don't imagine there is a problem with the socket
since
the filiments light. Its also a UV lamp.

I wired up a strobe once. It would not work in the dark. As soon as you
gave
it enough light it would fire.

I am reading the lamp FAQ.

The measurements on the orginal ballast are off. I may have a bad new
ballast

That won't work unless the ignition capacitor within the ballast is shorted,
which I've seen once, the yellows go to an isolated filament winding,
they're not part of the ballast secondary. Put the red wires on one end and
the blue wires on the other and the lamp will light. Better yet, use a
ballast designed to operate a single lamp, they're cheap.
