Greetings --

I'm working on a scoring issue where the 10s and 100s score reels are scoring simultaneously when the 10pt. features are triggered. For example, instead of 10pts when the rollover is triggered, it awards 110, then 220, then 330, etc. The score reels are clean and mechanically functioning properly, they zero out at reset, etc. I'm not sure where to look next.

Any suggestions would be greatly appreciated!

9th position switch on the 10s reel is definitely open at 0-8 and closed at 9 as it should be. However, I have noticed that it 'sticks' (electrically) from 9 --> 0. Although perhaps it could be mechanically sticking from 9 --> 0? Through all 10pt. features (or just manually engaging the N relay), both 10s and 100s advance.

I have even intentionally held the 9th position switch far away so it doesn't contact at all and both reels are still scoring.

Thank you EMsInKC! Will look into your suggestions tomorrow.

Merry Christmas!

No. It does appear that someone (wasn't me) may have resoldered some of the other tabs, but the 9 position switch solder tabs look original.

Yes, it does. However, it also scores the 10s. No matter what, they are simultaneously scoring.

The 10s relay (N) appears to be working fine, as do the 9 position switches on both the 10s and 100s reels. Also, the 100s relay (M) is in good working order. UGH!!

For what it's worth, the N (10pt) relay and M (100pt) relay are firing at the same time regardless of which one is pressed.

I believe at this point, I have eliminated the score reels and their respective switches as having anything to do with the issue.

Thanks in advance for any advice you can provide!

Thanks for your response HowardR! I was just looking at the schematic this afternoon and thinking the same thing, what ties these two relays together that could make them fire together. I'm away until after the new year and won't be able to pursue this until I get back. I will take a look at these 4 make/break switches when I get back.

Thanks again!

Bingo bingo bingo!!! I decided to start with just the first make/break switch on relay B and just lightly flexstoned it and WHADDYA know, problem fixed!! My 10s and 100s are no longer scoring simultaneously!! WHOOHOO!! I prefer the less is better approach so I'll stop there on that issue for now.

Now, I have a new issue in that the 10s chime is not working which I'll need to further troubleshoot. Any help or pointers where to start there would be appreciated!

And finally the 10s to 100s rolling over (from 90 to 100 for example, then 190 to 200, etc.) is not happening consistently but I know that's just a tweak of the 9 position switch on the 10s score reel (finicky bugger!!). I'll get that one eventually.

Thanks so much HowardR for your helpful insight!!

FIXED!!! I checked that switch on the (N) relay and could hear a hum from in the cabinet ... Checking the 10s chime unit itself, I could hear that the hum was coming from the coil for the 10s chime. Pulled the chime off and sure enough, the plunger was gummed up and stuck!! So I cleaned it up, put it back together, and all was well! Music to my pinball ears!!

I normally rebuild the chime units but haven't gotten that far yet ... so lesson learned.

Thanks again HowardR! I got the 9 position switch dialed in now on the 10s reel as well so it's rolling over the 100s reel. ALL IS WELL!!

Thanks! I have the schematic ... just not very good at reading them yet. Howard really did help point me in the right direction for which I am very grateful!
