Hi, I know that not all score reels are supposed to have boards, but does it make sense that only the 100 reel doesn't have one on this Pro Football? I'm troubleshooting an issue where 100 points is missed every few times. Happens with 500 and 300 scoring. Every 4th or 5th time, I'll get 400 instead of 500, or 200 instead of 300.

Thanks for the info and suggestions. The chimes are always in synch with the scoring, even when it’s wrong. I think this is happening with thousands too, so I’ll try to find out what they have in common. Score motor switch makes sense. Time to try to decipher the schematics. The 100s reel is not sluggish. I’m proud of how crisp it clicks on all numbers.
