I am new to the site, and to pinball repair as well. I recently acquired a 1967 Williams Base Hit in complete condition, but needing some love. I am able to start the unit up, see it zero out, and clear bases, and then it stalls there. No bat or pitching power. I noticed one of the two rollers on the pitcher unit was missing the roller that rides on the cam(See pics). After replacing with spares(thanks eBay), I restored power and now the pitching unit wheel continuously spins. I'm guessing that I may have not aligned switches properly once repaired. Still have no power to pitching or batting. I have the original schematic, but I'm a bit rusty on working through the ladder diagram. Is there any sort of troubleshooting guide that anyone can recommend? Also, should the tilt switch be in the open or closed position at startup?
I've attached pics of the schematic as well as the two switches on the D-6322-67 pitching unit. Any help that you all can offer is greatly appreciated. I played the buttons off of one of these as a kid, and would really like to get it back in operation.
Thanks,
Dennis
