Greetings All,

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.

Thanks,

Matt

Good to know

I am only getting 2.25v at the sockets on the door. Same at connector going into coin door interface board. Guessing there is a break in the wire somewhere or bad connection at the harness plug. I'll see if I can trace back to figure out where.

Thanks for the response.

Does this need to be done? I don't want to fix something that isn't broken. This machine is 100% LEDs.

Made the changes to board as you suggested and it's fixed now.
Thank you for your help.

Trivial issue I know, but it always bugged me that these didn't work.

You are correct that I was not measuring point to point. Noted for future troubleshooting
