I'm trying to get a Williams Ball Park up and running. When I power it up everything seems fine until I coin up. At that point it gets stuck in a reset cycle until I turn it off. In cycling through the reset the game over relay would keep dropping. I found a pc of cardboard folded and stuck into the Lock coil bracket which seemed out of place. When I removed it I would get the game over and tilt relays dropping after the reset bar cycled. If I put the cardboard back in only the game over relay would drop out. I did find a broken wire on the cabinet bottom slam switch but reconnecting that didn't seem to help.
I'm guessing that the lock relay is bad hence the cardboard to bypass it but any other ideas of where to look ?
