My score reels would occasionally get stuck between numbers. I took them all apart and cleaned them. I replaced the springs, coil sleeves, coil stops and applied a tiny bit of dielectric grease on the circuit board where there is metal to metal contact. New plungers were not available from PBR so I used the old ones. They reels are much better but sometimes when I score 10 points, the 10’s relay will buzz loudly and seems to hold longer than it should. The switches on the 10’s relay seem good. Not sure where to look. Any ideas? Thanks.

Thanks, I'll check that and report back.

Thanks for the link. Great info there. I tried hitting each switch manually but I can’t really make it act up unless I’m playing a game. It’s hard to tell if it’s the 10’s or the 1’s acting up. It may be both. I’m going to try to take a video while playing a game to try to narrow it down.

I think I may have fixed it. I had a machine gunning slingshot. It’s amazing I never even noticed it before. One of the switches was too close. I adjusted it and the problem seems to have stopped. Thanks for the help guys.

Ouch. Where did you a find replacement for that? Pinball Resource?
