Hello, I am new to fixing EM pinball machines but I am very close to getting my Gottlieb Jack in the Box working fully. The machine works almost perfectly once I have got the game to start, the problem is that the game will not start without some help. When I press the start button all the score reels reset to zero (I have manually set all reels to 1 to watch if they do reset to 0, and they all do). But, the score motor keeps spinning indefinitely. If I press the "U" reset relay, the game starts successfully and runs through the game normally, but never reaches a game over state. I don't think the game not ending correctly relates to the game not starting. What could be causing the score motor to keep spinning?
