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?

How far is it getting in the startup sequence from the Jack In The Box manual?

So currently I need to press "U" and the machine finishes the startup sequence, so the machine gets stuck at step 5. The thing is that all the reels do reset to zero, so that should mean it is making it to at least where the player unit is supposed to step up to zero position? Where should I start to look based on what I said?

If the Control Bank Reset relay (U) doesn't activate, Inspect and diagnose this circuit with Alligator clip jumper wires

One likely cause is the 'zero' switch in each reel unit. All of them have to close at '0' or the motor will just keep running after they have reached zero and reset will never complete. Check the switch in each one that only closes at zero, clean and adjust if needed.

Thank you for all the help! P5A was the problem, using the alligator clips the game started right up! Clean the switch contact and now it starts correctly!

I also have an issue still with the game not ending, should I make another topic on the forum or continue here?

Can you define what you mean by "Not Ending? "

If the Last Ball relay (XB) doesn't activate when the 4th ball of a 1 player 5 ball game drains, Inspect and diagnose this circuit with Alligator clip jumper wires

Thank you I will look at this. To be more specific, once last ball is over the player motor steps up again until there is no ball indication lit up, and still kicks the ball out. Furthermore any scoring does not give any player any points at this point. I also have never seen the "match" lights light up before on this machine.
