Nic Schell recently did a video over on Facebook about cleaning and adjusting relays. I only saw a tiny bit when it was live but there's some great info there.

I'll throw my hat in on the videos. I'm documenting some of the work while rebuilding a 1962 United Embassy Shuffle Alley.

score reel teardown
a tip to free stuck score reel parts

Quoted from PinDeLaPin:I hope this isnt a stupid question and I'm hoping somebody can give me a good answer but does the whole assembly that the scoring reels screw into come out of the back box? There's like a metal latch on the side of back box that slides but I thought it said that that was for the back glass removal. It's a pain in the ass to try to take these reels out up in the air and have them dangling down by the wiring. It would be a lot easier if the whole thing came out and I could lay it on the table and do them that way. Without a manual I am reluctant to just push and pull things that I don't know what they do.
I doubt it. On the latter United machines you pull the back glass and the reels tip down. I don't think your machine does this.

Quoted from PinDeLaPin:Is there a magic number of windings? Wasn't sure if too many would cause problems
Yep! To many turns & it might not step up completely. Trial & error is my motto when working on these units.
Nope, when I first started working on these units (Williams pinball) I counted turns. But I always had to adjust them tighter or looser. So now I just start with 2 or 3 turns and adjust from there.

I found a good United service manual here: http://www.arcade-museum.com/manuals-arcade/United%201954%20TEAM%20SHUFFLE%20%20Service%20Manual.pdf
It's not exact for your machine but it does a great job at explaining what each mechanical unit does and what the function of each relay is. This can be very helpful in troubleshooting
There are some other manuals here https://www.arcade-museum.com/manuals/manuals_em_arcade.php

You will be- as the mechanicals are the exact same. Just the lanes and ball lift motor are the main differences.
Good pics of the wire. I believe that wire is there to make sure the hub that the score reel screws to is grounded to the plate of the score reel mech. From what I can see the hub is a sandwich of metal & fiber cams. The wire should go on the top grove closest to the screws.
Quoted from PinDeLaPin:So not in the middle groove between the 2 fiber cams but above that one in between the metal and the fiber is this correct? If so that is the way I had it after reassembly.
Yep! you have it correct.

Nice work! Sometimes just working the mechs and contact points gets everything lined up and working correctly.
