Update on troubleshooting the start-up sequence problem with my Gottlieb Jack in the Box. The issue is the score motor just keeps running (original post here: https://pinside.com/pinball/forum/topic/gottlieb-jack-in-the-box-start-up-sequence-repair-needed-in-milwaukee)
Below is as far into the the startup sequence it makes it to (from the Jack In The Box manual thank you jeffc for posting):
Works---> 1. Inserting a coin or pushing the replay button actuates 'S' relay (Start relay).
Works---> 2. This relay will lock-in through its own switch and a motor 2B switch.
Works---> 3. 'S' relay starts the motor running.
Works---> 4. 'SB' relay and the total play meter are actuated by switches on motor 1A and motor 4B through a switch that has been closed on 'S' relay.
The next step is where the start-up sequence issue is currently isolated to:
5. Works---> When 'SB' relay is tripped, the reset relays 'Z1', 'Z2', and 'Z3' are energized in sequence to reset the score units and the 'player' unit. Works---> 'Z3' opens the circuit to 'Z2' and 'Z1' until all the 4th player score units and the 1,000's and 10,000's score units of the 3rd player are reset through motor switches. <-------This is as far as it makes it in the start-up sequence.
The next step should be---> When these units are at zero 'Z3' falls out and through a normally closed switch on 'Z3' reset relay 'Z2' is energized. Z3 does fall out Z2 does not energize (have not checked with meter).
So, lets say the game is turned off. All 4 player reels have scores on the them. I turn on the game, insert a coin and press start. The score reel starts and player 4 and player 3 score reels reset to zero. Score reels for player 2 and 1 do not reset. I can see Z3 relay falls out. So now I have the sequence isolated. Thoughts on what to troubleshoot to determine why Z2 does not energize?
For what it is worth, this is the remainder of the sequence:
'Z2' opens the circuit to 'Z1' until all the 2nd player score units and the 10's and 100's score units of the 3rd player are reset through motor switches. When these units are at zero 'Z2' falls out and through a normally closed switch on 'Z2' reset relay 'Z1>' is energized. 'Z1' stays energized until all the 1st player score units are reset through motor switches. At the same time the player unit steps up to its zero position through a motor 1A switch in series with a switch on 'SB' and a run-off switch on the 'player' unit (P5B).
6. The control bank is reset by a switch on motor 3C through a switch on 'U' relay.
7. Inserting additional coins or pushing the replay button will actuate the 2nd player relay (PB2) through motor 4B switch; the 3rd player relay (PB3) through motor 2C and PB2 switches; and the 4th player relay (PB4) through motor 1D and PB3 switches; in that order.
8. Place the ball in the outhole. The outhole switch completes a circuit to 'E' relay. A witch on 'E' relay completes a circuit to 'F' relay through motor 3C. When 'F' relay energizes it closes a switch that completes the circuit to 'O' relay if the bonus unit is at zero position.
9. 'O' relay locks in through its own switch and a switch on motor 2B.
10. When 'O' relay is energized the motor starts running.
11. Motor 4C actuates the ball return coil (which kicks the ball onto the runway) through a switch on 'O'.
12. The ball is now on the runway and is ready to be put into play.
13. The remaining balls that enter the outhole are kicked across the trough switch which pulls in 'P' relay. 'P' relay runs the motor. Switches on 'XB', 'ZB', motor 2C, 'P', and motor 1A advances the 'Player' unit the required number of steps determined by the 'Player' unit switches and the player relays (PB2, PB3, PB4).
