Quoted from vipertblck:is there maybe a switch somewhere on the score motor thats suppose to be closed until all the reels reach zero and the game resets and then open?
Yes. That switch is controlled by the Reset relay shown above. If you watch you'll probably find that the Reset relay lets go, then the Score Motor stops soon after.
The reason it takes two Replay button pushes to get the game to reset is that your Reset relay is likely only staying active for one Score Motor cycle (or 1/2 turn), which only provides five reset pulses to the Score Reels. If you have any Score Reels showing numbers 1-4 at the start, they take more than five pulses to reset. The second Replay button push repeats the process and provides another five pulses to the Score Reels which should reset them all (assuming they're working well).
I'm pretty sure that one or more of you 16 Zero position switches isn't closing as it should. It may be closing visually but unless it's conducting electricity it won't keep the Reset relay active into a 2nd Score Motor cycle. It could also be a problem with the wiring, the jones plug, etc.
If you manually put a 1 on all 16 Score Reels and start the game, does it reset properly? If so you might be able to experiment by setting one or two Score Reels at a time with 1s and trying to reset the game. Some may work just fine. The ones that don't would probably be where to look.
