Chris,
Installed the repaired ballast and turned it on, the light came on and stayed on until the timer turned it off, when the timer was to turn it on, the light did not come on and now does the exact same thing it has been doing all along (turns on for a second and then turns off immediately) Is it possible that this one ballast has other issues? Can I return it for a replacement?
I don't think the problem is in my light wiring, or electrical source. I use another light in there without problems when this ballast was out for repair (twice now) and I can take my one working 660 and put in there and everything works fine.
I think this one has other problems, would like to replace it please.
Thanks,
Mark
