Looking for any wiring diagrams or schematics for a United machine. This one has the WIS CON SIN theme, ball rolls onto glass to shoot, nine letters, which most of these types of machines have, so I'm thinking that any diagrams out there would be very similar in nature to this one. It worked nicely until I took it apart for pictures, so I think it's most likely one of the pin connectors that is causing it to act up. Anyway, a schematic diagram would be helpful. I have put this machine on the shelf until I find any information on it which might be helpful.
