Does anyone have a clearer schematic than the one available on IPMD? I am trying to diagnose a couple of issues and can't quite make out the switch configurations.

The first problem is that when the tilt bob is in place the game starts up but moves to game over as soon as a point is scored. When the bob is removed, the game plays normally. The bob is not making contact with anything other than where you hang it.

There is no separate tilt light or function that I have seen. It just displays game over.

I do not see a rolling ball or mercury tilt mechanism. There are two weighted tilt switches in the base in addition to the bob. Both of them appear to have space between the contacts. Does anyone have a picture of the appropriate spacing for the tilt switch next to the bob?

Interesting development. I started the game without the bob, scored some points, put the bob back in, and manually moved the bob to tilt the machine. The tilt actually lit up and ended the game, no game over displayed. I then started another game with the tilt bob still in place, it played normally, and did not display game over as soon as a point scored. Not sure how or why that happened, but I'll take it, because I just picked up a Bally Pool Shark project. I truly appreciate your help MarkG
