Hello everyone, I've gotten my target Alpha up and running from the dead, the only problem I'm having for some reason is in player two, three, or four the last ball won't end game. When the ball ends the game the game automatically resets and starts a new one. If it's in one player it ends the game properly. Game over light starts flashing showing game is over. The player wheel is in excellent condition( cleaned, aligned and all rivets omh out properly) seems like I have some kind of bad connection from the player wheel to the last ball relay when in second ,third and fourth. I don't have a schematic for the game. Any help would be appreciated.

Thanks, all fixed. Bad connection on the last ball relay.
