I thought I’d make it tougher on the grandkids changing from 5-ball to 3-ball per game. I set the plug in the backbox to 3-ball. I played a game, everything played as expected but when the 3rd ball drained, the game counted the bonus points, the match number activated, the Game Over light came on but I noticed the “Ball in Play” light advanced to 4 instead of going just going out. It did NOT kick out another ball. Should the Ball Count Unit advance all the way as if it was the last ball for a 5-ball game. Pics below show the "Game Over" and the Ball Count Unit.

Thanks
Steve

Hi, Thanks for the tip.. I pulled the plug and the 4 light stays on... I'll start back tracking from there.

sorry... unplugged...

Got it...

I traced it back to the "Game Over Relay". The MB switch F needed a very fine tweaking adjustment. All 3-Ball games and 5-Ball games function as it should.

Thanks
Steve
