I'm working on a 1975 Bally 
Wizard!. I'm down to just a couple glitches, but the one that has me stumped in the Credit unit. It will increment just fine if you win a game by score or match, but it won't decrement to use those accumulated games. If you manually cycle the unit (slowly), it goes up and down, but in real play (which cycles the coil much faster) it won't go down at all. The coil does fire when you start a game, or add players, but the games won't come off the unit. I can't see anything obvious. I've torn it down, and there's nothing sluggish about it. Anyone have any tips on adjusting this thing?
