Ultra Shuffle Alley IV

Yesterday, the parts I ordered came in.  I received the schematics, 100 replacement bulbs, and a new coil.  Unfortunately, the coil was not the right one.  I had taken a guess based on some schematics of similar systems by United and thought it was worth a chance.  It was the right gauge wire and close to the right number of turns but the inner sleeve was the wrong diameter.  The part I ordered is A-24-1000.  The one the schematic calls for is A-24F-1100.  The last number is the number of turns. I had seen on the internet that the particular one listed on the schematics is very difficult to find.  I decided that I could re-wind the old sleeve and make a part or two to build a coil that would work.  Basically, the replacement part I'm making will be a little stronger than the original because the number of turns is less.  I think it should be fine.  The following are some pictures of how I did it...

Bolted up inner sleeve and newly made end cap.

I've got the new (wrong) solenoid in the vice so that it will spin freely.

The bolt in the first picture was too short to chuck up in the drill.  Got a longer one.  I'll basically take the end of the wire and start spinning it off the coil on to the newly cleaned and fixed up spool.

Here it is after the transfer

I got the newly recoiled solenoid back in its mounting bracket and ready for installation in to the game.

Here it is in the game.  I used bolts for terminals and ring terminals crimped on the wires from the game.  This will make it easy to remove in the future if necessary.

 I cleaned up some more contacts and some of the scoring reels (player 1 and 2).  The reels are very delicate and time consuming to work on.  All of the reels need to be taken off and Very very gently washed.  In addition, all of the lever arms need to be taken off and cleaned using rubbing alcohol.  It will take a while to get through everything...

After opening the Back Glass, the scoring reels unlatch and flip down on top of the pin hood for easy access.

 

 

I put it all together and tried it out.  Not everything was working at first.  I must have messed up one of the contacts on the "Game Over" relay.  After inspecting it, I could see that several of the contacts needed adjusting.  I adjusted them and everything works!  For the first time, the player up lights, strike,and spare lights have lit up.

Notice the tenth frame lights are lit, the 2nd player up lights are lit and that player has a strike.

Player one up and he has a strike from the last frame.

The end of a game with the "Game Over" lights.
