I am new to the forum and looking for a little help in my journey to resurrect an old Shuffle Alley into working condition once again. Here is my story...

I recently purchased what I believe is a 1953 United Shuffle Alley machine that perhaps has not been powered on for 50 years. I did my homework and took my time taking apart all the steppers and score wheels, cleaning and lubricating them. I also took apart the pin reset motor in the head (drilled out the rivets) cleaned and lubed that as well. I visually checked for loose wires, bad connections and mouse damage. Luckily all looked good. Yesterday was the big day! I powered it on!!!! The good news is it starts a game, the pins come down and the score wheels reset to 0. With the play field open I manually trip a pin switch with my hand the pins retract. Then I manually trip the rear puck switches with my hand and nothing. I would expect that to then trip the 1st shot relay, but it does not. Now, I manually trip the 1st shot relay, then trip another pin, then manually trip one of the rear puck switches the 2nd shot relay trips on its own, and the game advances to the next frame. I have checked, cleaned and adjusted the switches on the 1st shot relay and tested the coil with an meter, which is good. I am pretty new to this EM stuff so any help in further troubleshooting would be great. I am guessing I can try to jumper from the rear puck switches to the lugs on the coil??? Anything else I should be considering?

The rear switches do trip the 2nd shot relay so they seem to be working. But I should to that anyway....

Mopar that is some good info/tips right there. I will give your suggestions a try over the next few days and report back. As for the name of the game it is United's Liberty Shuffle Alley. Here is a picture as I found it. It really cleaned up pretty nice and I took a lot of pics along the way.

Yep all the pins are good! Looks like the 9 pin was replaced at one time. If you have a digital copy of the schematic that would great. There is a dusty schematic underneath the play field but to have it on my computer would be awesome! And yes we will get her....

So I put an alligator clip on one of the rear rollover switches and took a small screwdriver between all 4 closed switched and nothing happened. However, the screwdriver slipped at one point and contacted two of the closed switches at the same time and the relay energized and tripped. So it seems like the coil is good. I also took a really good look at all the solder tabs and they all look to be in good shape making good connections. Based on this info would you think I have a broken wire? It was kinda hard to tell if the color code of the wires matched up. I did not try to jump anything at this point. Mopar would love to hear your thoughts.....

Sounds like a plan. I will try to locate that wire this weekend. In the event I need to fix this by soldering in a new wire would it be best to go from the rollover switch to the 1st shot relay or the first position on the score motor? Also what gauge wire would I use? Thanks for your help!

Nice! Your backglass ins in way better shape than mine! There is a dusty schematic inside the machine that has Cascade crossed out replaced by Liberty. I am going to try to take some photos and stitch them together in a PDF. I used a piece of 1/16 Lexan to make the pin surround. I'll post some pic's this weekend. I am probably going to use some Lexan for the bottom shield as well.

And thanks Mopar will keep you posted!

Good news! I cleaned the contacts on the 1st position score motor switch and it started working!! I cycled through 10 frames on single player and it seemed to work fine with the exception of the player 1 (tens) score reel not moving. 0-9 works fine. That will be the next thing to look at. Also here are some pics of the 1/16 Lexan. I bought a precut piece off of eBay. Slightly short but I made it work.

I’m happy to report after a few more obstacles she is now in working order.
