I've had a scared stiff for a few years and the coin door lights have never worked. I finally got around to messing with it today. According to the manual power is supplied from J110, I am measuring 7.42v AC on Pin 1 (white) and 5.4v AC on Pin 3 (purple). There is a hack directly adjacent to the J110 connector that was there when I bought it, that I have not ever looked into or messed with.
Can someone help me make sense of what I am looking at here? The diodes have all been cut out and 4 Jumper wires have been installed. There are also some very obvious burn marks. D30 would also go to J110 Pin 3, which goes to coin door. Is this hack a potential part of the problem?
First two photos are of the hack in question, 3rd photo is of MM for comparison.
