I have just inherited 2 pinball machines, Cross Town 1966 Gottlieb and Sharpshooter 1979 Game Plan, from my Uncle Mickey in Chicago. I managed to drive them to Southeastern Massachusetts and set them up. Both turn on and Sharpshooter plays well (a few broken tabs and I already fixed a flipper) but Cross Town's score motor keeps going round and round and round. It plays while the score motor keeps turning, but no scores register and the game never ends, I assume because the score motor needs to reset (stop going around) before the game can actually start. I have a schematic, which I don't really understand. I am a beginner.
Also, someone has put in an alligator clip wire going from the 110 volts main fuse to the transformer. Without this the alligator in place the machine won't even turn on - hopefully I can figure it out!
