Getting back into the game room a bit and trying to get everything sorted before the holiday traffic. On my SO76 I can get through playing balls 1-2 but at ball 3 it skips to ball 4 (sometimes ball 5) and then the player 1 score reels start thumping to the rhythm of what I think are the reset coils - it does this until I shut the machine down and restart. Any ideas on where to start? I have yet to dive in so it might be fairly simple to see whats happening when I do get into it- but a little bit of direction or a clue as to why this is happening is greatly appreciated. Thanks guys!

Dirt- thank you very much

Not sure if the issue is only on player one but I believe that it is the same for all players- if it skips ball 3 on player one it will skip ball 3 on every one- but I'll check tonight. I ran through a game last night and I was able to play ball 3 but then is skipped ball four and started it's thumping.

I'll manually check the player unit tonight ( this is the unit in the head if I am not mistaken)
