Help on Ballast Question
Hi. This isn't about my home, but I get good advice here often, so...
I have a deli case at my store with 2 4' fluorescents and 1 3' fluorescent bulbs. Of course the deli case was manufactured in China and the ballasts have Chinese lettering on them. They are very slim ballasts and the supplier of the deli case is pretty much worthless other than being able to sell me new ballasts.
I replaced all the bulbs and they don't light, so I assume it is the ballast... but all 3 not working at the same time? One of the bulbs glows orange near one contact, but just a little. The other two lights do nothing. I can't tell how they are wired exactly. Each fixture has a cord going into the housing of the case separately, so they are not wired in series, at least from what I can see.
My question is how likely is it that I might just need 1 ballast to make all three fixtures work again? I have trouble believing that all three ballasts went bad at about the same time. I will check to see if I can find any wiring info on this thing.
Any recommendations, or do I just have to go buy 3 new ballasts from them?
