1). Can anyone give me the open/closed score reel positions for a 1974 Bally Champ (I'm assuming this is the same for similar-era games). I'm working on a project and the current switches are just all over the place ... so much so that I can't determine a pattern or which are right. Specifically, I need help with the the "1" - "8" positions. Position "9" is clearly Closed/Closed/Closed (starting with the switch closest to the solenoid) and position "0" is Open/Open/Open -- but the "1-8" switch positions seem to vary between Closed/Closed/Closed and Open/Closed/Closed.
2). Can anyone tell me how to read the schematic to figure this out myself? I have the schematic, but I'm just not advanced (aka "smart") enough to figure it out on my own.
