Hi,
I'm attempting to help my buddy repair an issue with his 1951 United Deluxe Shuffle Alley. He lives 150 miles from me so I am doing this remotely. I may be able to see it in person around the holidays.
The malfunction just applies to player #1. When a game ends and a new game is reset the #2 thru #6 player's scoring correctly reset to zero. However, player #1 does not reset to zero. If player #1 had a score of 207 in the previous game, the new game starts with 7 points for player #1. If I a previous game score of 192 then the new game score starts at 2 for player #1, etc. The scoring on this game is with back-lights not reels. (brochure picture attached).
So in the first frame (if player #1 is showing 7 points) and player #1 gets a strike (which is worth 30 points), the score advances to only 27 (not 37). If player #1 only gets 8 pins down the score advances to show 5 (not 15). Once player #1 gets a strike or a spare, the scoring is correct the rest of the game.

I am guessing that there is a make/break leaf switch for player #1 that is not breaking at the "zero" reset mark and runs too far? If so, where might this switch be located? (schematic is attached)
Any help is appreciated!
Bruce

Hey fireball2 that would be great to see some pics until I can get over to his house.

I did a repair on the machine a couple of years ago and I do recall there being separate steppers (and no return springs as mentioned).

He did say that when the game resets and the #1 player is showing a number (other than being zero like it should), he can manually advance the stepper to the zero position.....BUT if a strike is made only 20 points score instead of 30. Every frame after that scores correctly. However, if a strike or spare is not made the ones score keeps advancing but does not activate the tens until a mark is made.
Example: Game resets and 7 is lit. The ones stepper is manually advanced to zero. Say after two throws a total of 8 pins are down. The ones score advances to 5 and the tens stepper remains at 0. This process continues until a mark is made....only then will the tens stepper advance.

It seems like the ones stepper is loose enough to rotate through the 10 positions but does not stop at the zero position on reset. Is it possible that the tens stepper is off just a tad when it resets....and that would keep the ones stepper from going to zero? That may explain why a strike only scores 20 points instead of 30 points?

I'm just hypothesising here.....I hate not having the machine in front of me.

Thanks for any help!

I asked my friend to pay close attention to all of the players score stepper units when the game resets. He came to the conclusion that the tens stepper unit on player #1 is resetting too far (past the zero mark). I thought there would be a stop to prevent this from happening but apparently there isn't.
Is there an adjustment that can be made to prevent this?

Thanks, I appreciate your input.

Hey fireball2,
My friend can't find the mounting screws on the stepper plate. If you could take a pic of your tens stepper unit and point out where the mounting screws are I will forward that info to him.
Thank you

Thanks Mark,
I forwarded your post to my buddy. He should be able to figure out the adjustment with your info and pic. I appreciate your time and effort!
