It kind of sounds like your trough switches are making, causing the game to go to game over. Try gapping them a bit more perhaps?

Hi Ohio66
maybe switches (in the JPG) "B,C,D" are (also ?) faulty (?) --- I believe the Switch "A" is faulty. When You start a new game and the pin resets the Score-Drums: ALSO the Ball-Count-Unit is resetted to "Zero-Position means ready for Player-1 to play Ball-1". So switch "my A" opens. When in Your pin this switch is faulty closed - the "still" pulling Coin-Relay in the Start-up Procedure makes the Game-Over-Relay to trip again. You probably have two or maybe three (?) switches on the Ball-Count-Unit - look for the switch with wire-Blue-White and wire-Blue-Red --- is this switch OPEN when the Unit is resetted ?

This switch "A" was for the Arcade times --- people where starting a new game - played one or two balls - said "what a lousy ball - I do not want to play the remaining balls - I press the Credit-Button (Coin-Relay pulls-in) and start a NEW game". And the pins need the pin in state "Game-Over" - so switch "A" as the Unit beeing stepped (one or more balls have been played): Switch "A" is closed and makes the needed "Game-Over". Greetings Rolf
