I recently purchased a Shuffle Inn puck bowling machine off of Craigslist that I'm trying to restore. I have fixed the system board so the machine doesn't fall into maintenance mode every time you turn the machine on, adjusted all the play field switches, fixed many contacts that were broken, replaced the bumpers, swapped bulbs for LEDs, and have ordered new display boards.
I have one set of wires I can not figure out. I have attached a picture. From what I'm gathering, there should be a light behind the credit button, although the manual doesn't reference this. Does anyone know what part I'm missing and where I can get it? I've asked a couple of pinball repair places, but they don't seem that interested in helping me. Any ideas?
Thanks. Brian
