New coil installed, and some other bits and pieces fixed/replaced. We're almost there.
Currently we have an issue with the tens (10-90) score reel.
* The game will start normally and play, and the scoring works fine for all reels (including the 10-90 reel). The problem is that during reset, the reel never turns or goes to zero, yet the game thinks it's at Zero/Reset position and starts up as it should.
* The score roll-over works fine, so when the 10-90 reel rolls over to "0" again during game play, the 100-900 reel advances as it should.
So it seems all of the in-game scoring portions of the reel are good, but for some reason it never receives the signal to reset during the Reset process, and doesn't care that it's not at Zero/Reset position when starting a new game. As long as the other reels reset, the game starts normally.
Thoughts on what might cause this?
Note: I found that on some of the other reels, there is a "jumper" connection (looks original and normal) between a couple of switch connections. It appears that the little jumper on the 10-90 reel is snapped, but I can see where it went. I jumpered between them, and the result is that the score reel still doesn't turn/reset, but the game gets stuck in a reset loop. I'm guessing someone realized that if they broke that connection, the game always thinks the reel is in "zero" position when reset.
Thanks in advance, as always, for advice! I have the schematic, so if pics are needed, please let me know. I can add pics of the reels and switches too, if that helps.
