Hello everyone, I have an IGT S2000 Triple Stars 3 reel machine that would not boot and I found out it was the top box light ballast was shorted. I unplugged it and the machine works good. The reel light works. The belly light will not work. I have put a new bulb in it. I turn the machine off before I remove, install or unplug anything. Besides the bulb what else could cause the light not to work? Can I test the DC voltage at the balast. I have a wiring diagram but I think it is for the vision machine. I do not see the top box balast on it. Are all three balast daisy chained together? On the diagram I have it looks like the belly and reel ballast are daisy chained together. I guess it might just be a bad ballast. I would like to know before I order because if I need 2 I will order 3 to have an extra one. Thanks
