I've had a reoccurring issue with my Williams Ringer zeroing-out the score reels during startup and I want to see whether my logic is sound and I am troubleshooting the issue correctly.
During the startup sequence certain reels are sluggish and don't seem to have enough power to advance the number on the score reel to the next digit. I have cleaned and adjusted the score reset relay switches many times, as well as the switches on the score reels themselves. Sometimes I can get it to actually work for a few games but the problem will come back and I'd like to fix it once and for all.
I have noticed that on some occasions when I am cleaning/adjusting the score reel switches, the problem will drift from the 10s digit to the 1s digit, and it may drift from player 1 to player 2.
Here are things that I have noticed during troubleshooting:
1- If I manually zero all the score reels and start a game, the game plays and scores perfectly. All score reels advance properly with no hesitation
2- If I power the game on and manually advance the score reset relay, all score reels will zero-out properly
3- All of the screws holding the switch stacks on the score reels and reset relay seem to be tight. There is no play if I try to wiggle them
I know that most people (myself included) will read this and think that the issue has to be with my score reset relay switches or the score reel switches, but is there anyplace else that I should look? I really feel like I've ruled-out those switches at this point.
Here's a video that shows the problem:
Thanks for any suggestions!
