Just picked up a Space Shuttle recently, and it's playing great aside from one issue, which upon research looks like it's all linked together. All of the stand-up switches around the playfield (behind rubbers) and the Lane Change function that keys off the right flipper are non-functional. Looking at the manual, I can see they're all linked to the same Wire and connector (Green-Blue, 1J8 Pin 7).
Looking under the playfield, I found that every single one of the associated switches has a diode on it... but all the diodes are disconnected for some reason (someone cut one side off, so it's just dangling there). Thoughts/suggestions as to why someone might have done that? Maybe they couldn't find a switch issue, so just killed the whole chain? Not sure if I should just reconnected all the diodes or what. Open to suggestions.
Thanks!
