Working through some issues with an EM Bally Old Chicago. I've got most everything working except ALL the bumpers. Since none of them work at all I'm guessing the issue is not at the bumpers themselves. I don't have a schematic on this so I could use some advice on where to start.
Are the bumpers on their own circuit?
Assuming I should start at the transformer/power supply, which taps and what Voltage should I be getting?
Old Chicago was 1976 so I'm guessing other Bally pins of that era should be similar. I will give points for wild guesses even if they are not correct or don't help!
Extra credit for advice on 2 targets that won't reset. Even when I manually move the solenoid they don't come up all the way however if I pull the individual targets up they will come up, lock, and go back down as they should.
