So my Space Odyssey Starts on Ball 2 and won't switch to 2 player mode without rolling back the player reel, or holding the ball index open when pressing start.
I've been focusing on the player reel, figuring that was gummed up. It's not.
When pressing the start button, I watch the player reel, and it resets, then advances twice (putting the machine on ball 2)
If I press the start button again, it repeats the above. It's the second advance that strikes me as odd.
If I move the player reel back one manually it switches to ball 1 and I can press the start button again to switch to 2 player mode, and everything plays fine.
One thing I noticed is that the ball index relay starts up as activated right after pressing the start button, before scoring any points. (Not sure if that's normal for this game)
I held the ball index relay back from being activated, and pressed the start button, and the game reset and stayed on ball one. I was able to press start again to add the second player. Possibly something is activating the ball index before it should?
I feel like my problem has to be related to the ball index relay or whatever activates that... Possibly on the scoring motor during a reset?
Any clues to point me the right direction. I feel like I'm close, but just haven't pinpointed the problem yet.
