Hello, and greetings from Austria! (I purchased my pinball machines when I lived and worked in Upstate NY, but have since moved to Austria and could not part with them ) I'm fairly new to restoring these, and have been working on this for quite a while now. I've finally got everything working perfectly except 1 last item that simply has me stumped. It is a 2 player unit, and when on either player, if the 10 - 90 scoring reel gets to 90 the scoring simply locks up until that player is done.

It is as if something gets stuck and prevents the 9 from going to 0.

All scoring reels work smoothly, and all reset perfectly at the end of a game, and interestingly, if either player never gets 9 of the 10 point targets, the rest of the scoring continues working perfectly.

Does anyone have any experience on a similar machine as to why it will not advance from 90 to 100?
