Im working on a Bally Centaur 2. There is a major hack coming from the lower cabinet power board. There are 2 bridge rectifiers added to the steel mounting plate for the board. I know there was a service bulletin at some point recommending this to help with bulb life or something..they were overheating I believe. Anyways only 1 is hooked up, and not sure what the wires go to on the right side, also unsure of the plug with the white / green wires should go to....anyone have one that could send me a picture?.Thanks.
