Hey Guys, I know this is common knowlege to many of you, but I need a little help.
I've got a shopping center sign that we went to repair and ran into a problem we couldn't easily fix. It's a huge sign with several sections. Most were fixed with new bulbs or a ballast, but we couldn't get one sections working 100%. Actually we only got it 20%. It has 5 6ft High Output bulbs and a USB 1232 ballast. We tried bulbs first, then a new ballast and still could only get 1 buld to fire. What else is there to check? One socket was questionable, but with that ballast the other bulbs should still work. If the ballast is working properly what should a meter read on each socket? What is the best way to find the problem? Any help is appreciated.
