This is a long shot question here since I know this machine is not very popular. I have a Bally Beauty Contest that will not trigger a game over state. So I think something in not triggering the game over relay once the ball has drained (it is a one ball game). It looks to score properly (numbers light up corresponding to the bumpers hit), does not pay out though since the game does not end. It registers credits, increments the counter etc. There is really not a whole lot to this game and I am somewhat familiar with bingos but not overly knowledgeable. Just seeing if maybe someone might be able to point out something stupid I am missing.

I am pretty sure I was able to trigger a tilt and the game did end. I am not sure if I it can be tilt/ended while in the out hole since its spends a pretty short time in there. I probably wont get back to this game until next week some time but thank you for some direction on a few things to check. Unfortunately I do not have a schematic, I looked around a bit but was unable to locate one.

Wow, thank you for posting these I really appreciate it. So I didn't have any real amount of time with this machine today but I at least confirmed that I can tilt out of a game and trigger a game over state. So I am guessing the game over relay is probably ok. I will take a look over these schematics and see if they shed some light on this issue.

Just wanted to follow up on this. It did end up being the score counter reset coil. No idea how i missed it but the coil was toasted.

Is it still possible to get those little plastic cuffs that are clipped onto the coil plungers? Looks like they are used to guide and center the plunger in the coil sleeve. The one is really beat up. I couldnt find them for sale anywhere.

Thank you for the part number.
