This is my first EM pin end to end resto, not quite finished yet but pretty close (just waiting for some parts form pinball resource)/ cosmetics only to go. I have learned a lot throughout this resto but the main thing I have learned is how much more I need to learn! but hopefully some useful info will follow.

History

Machine was part of a job lot I bought from a collector who imported a container of US games. The game only has had one US owner who was an op. He bought the game from the factory and put it straight into his arcade and when it closed down (early 80's) he put all his machines into a warehouse where they sat for the next 27 years...this is where I also got the bowler and CC Home Run from plus some other pins and Em games.

The machine has not seen a lot of work, backglass is easily a 10, absolutely perfect, playfield is a 9, the only visible wear is from the kickout hole. Centre plastic broken but all others in good nick. One target broken. Pop bumper mylar in good nick with no wear underneath. Cab is solid but a few scrapes, Coin door pretty good (8) and apron pretty good (9).

Game has original manual, schematics, scorecards and uncompleted warranty card sitting in an unopened envelope at bottom of the machine. (always exciting to find these in NIB condition) :) Another thing that amazes me is that the original head shipping blocks are all attached and have never been removed since they were put in place. This means the backglass has never been out and the globes (that still work) are the original factory ones - GE44's made by GE themselves cool :cool: Serial number 9911 - the prod run 10,300 and numbering began at 3001 so the 6610th machine of the 10,300. Wayne Neyens received the 10,000th game produced and it was the only pin he ever owned (IPDB (http://www.ipdb.org/machine.cgi?id=2293)).

I had to drill coin door lock (to find the key sitting inside, doh hate that). Heres some pics of the machine before I did too much..

Initial Pics

As can be seen critters have been living happily in the headbox at some stage. The machine is dirty, not always a bad thing, the headbox the worst and under playfield and inside cab not quite as bad. You can see a couple of the inserts are missing - I found them inside the cab in good condition (bloody op mylared over one of the holes as opposed to going looking for the insert - wtf? - guess it makes sense given he didn't send his warranty card back either!)

The plan is to get the machine working and then address the cosmetics. Next post I'll start to list the faults found and the fixes needed.

Spirit of 76 was also a movie in which DEVO had a role...

http://www.imdb.com/title/tt0100670/

Movie was made by Rob Reiner (also created "This is Spinal Tap")

Just thought I would mention the Devo link.

Thanks for posting Stu. How nice is that backglass ! they look great when the reds are actually still red, not a faded pink.
My two player version Pioneer will one day get the treatment so I'll follow this resto for sure.

Yeah Woka, It's a sought after machine , some collectors reckon it's the best EM ever made.

I have heard that as well, (on the net <_<) Can you tell me what gives this game that distinctive awesome game feel, just curious thats all, never played one.

BTW looks like a well kept (away from playing) machine stuba, shouldn't be to much trouble at all:)

i'm dirty Nick, but not as dirty as darbs :laugh:


Nice work Stu-love that you know the history I'd love to know where some of my machines have been..Good luck with the resto

thanks Pete, I love drinking beers and talking about them as much as playing them ;)


thats the only way you could outscore me :)

I'll bet you a case of beer you can't beat foot at any game you choose at MM1 EB. He's a rare gaming freak and is just as good at pins as video arcade :cool:

had a lot of comments re the backglass, I consider myself very lucky to have scored such a nice one. it is a very fun game to play but you really have to work it to get a decent score ;)

ok back to it..

I thought it would best to doc the faults on this machine so there is a permanent record which may prove helpful to anyone working on one of these Gottlieb EM?s. This is an Ax Bx relay game and other games that use this setup are all Gottlieb EM games after super soccer in 1975. This includes El Dorado, Soccer, Fast Draw, Pin-Up, Quick Draw, Spin Out ,"300", Tiger, Top Score, Abra Ca Dabra , Gold Strike, Lucky Strike, Spirit of 76, Bank Shot, Pioneer, Spot Pool, Sure Shot, Royal Flush, Card Whiz, Buccaneer, Ship Ahoy, New York, Surf Champ, Volley, Surfer, High Seas, Target Alpha, Canada Dry, Jacks Open, Kicker, Solar City, Big Hit, Team One, Bronco, Mustang, Lucky Hand, Jungle Queen, Lucky Card, Centigrade 37, Jungle Princess, Golden Arrow, Super Spin, Jet Spin, Vulcan, Cleopatra. This list is exhaustive but I?ve done it mainly so that if someone searches one of these games they will find this thread.

AxBx relays are really hard to work on because the switch throw distance is tiny. They have to be adjusted perfectly to work properly. I found pulling the bottom of the cab out made things much easier but did involve having to disconnect the chimes, coin door and flippers.

Connectors

The connectors were covered in crud that looked like some sort of oxidisation. I tried cleaning them with 600 grit but found it to be too tedious. I discovered that the dremel wire brush worked a treat in cleaning them up as it was fast and easy to get on the hard to get parts as it is small. Before and after pics..

Steppers

Cleaning these is well documented elsewhere so I won?t waste a lot of time explaining it. I favour pulling them down and giving the moving parts (not the Bakelite plate) a shellite bath. Shellite is harsher than isopropyl alcohol but I like it because it?s much cheaper and gives the same result. Paper towels and cotton buds work well. There is the coin unit in the bottom of the cab (number of players), bonus unit (bottom of playfield). Credit unit in backbox (credits up and down) and the player/ball unit in headbox.

Score Reels

This game uses the Gottlieb decagon units. They are relatively easy to clean and get working properly. This was a comprehensive job as can be seen from the animal/insect crud amongst the switches. All switches needed fine sanding and adjusting. 4 player games (16 reels) are a real pain in the ass time wise. I did discover a broken switch on one reel (see blow) that was easy to swap a new switch into.

http://i599.photobucket.com/albums/tt80/stuba_bucket/spirit76/init14-1.jpg

These units have a circuit board/mini stepper type thing attached to them, these were in poor condition and needed a fair bit of attention (see before and after shots)

Power On

Once the connectors, steppers and score reels were done we (I had Travis and David AVD) assisting at this stage decided to power the machine up and see what happened. Always a interesting moment but it was an anti-climax. Machine lit up but would not start a game.

What followed was much mucking about testing different theories, consuming beer and generally not achieving much. Although I did manage to bring the playfield crashing down stuffing a flipper mechanism and coil ? nothing like making it worse before making it better. We managed to manually kick some relays that started reset routines but could not get the machine going on its own. The bottom come out next and every score motor switch was cleaned. I felt sure it would work after this but of course it didn?t. Project got shelved for a few days as I thought about it.

The next most useful thing was finding and printing Clays startup guide (http://www.pinrepair.com/em/index2.htm#start) for these machines. Together with the schematics (which previously only David could understand) we at last understood what the process should be and what should kick in order. We noticed that the Ax relay was not pulling in of its own accord. Tested for voltage at the coil and none present. Tracking the wiring back upstream we noted that the voltage should be going through the ?U? relay, pulled the ?U? unit and as you will see below the coil was burnt to a crisp.

http://i599.photobucket.com/albums/tt80/stuba_bucket/spirit76/Picture170.jpg

Soldered in a new coil and the game started up perfectly (notwithstanding a couple of stubborn score reels). The other point to note was that we pulled the playfield out which isolated any playfield issues from the startup routine. This helped a lot in focusing in on the correct routine without any other weird probs affecting us.

Free Play

There is a switch on the coin unit that closes when there are credits on the machine. A cable tie on this makes the game free play. Worth doing, quick and painless.

I?ll tackle the playfield errors next..

Very nice find. Cant belive that the original backglass shipping blocks were still in place. Dont see that very often? In fact hadnt seen it at all till now:)

yeah, i got a few of these types in a job lot. most still have shipping blocks attached and all original paperwork looks unopened. promo key tags still sealed in their plastic bags in some. looks like the op just bought them, plugged them in and when they broke retired them to the warehouse.

reminds me I must update this thread as this machine is finished now and all set up for the big meet. have got more of these projects to launch into once the meet is done :)

given i've just finished a gottlieb bronco and about to start a target alpha (which i'll do a thread on) I better finish this thread off.

Once the machine was going a few faults showed up:

this was one of the pop bumper coils:

http://i599.photobucket.com/albums/tt80/stuba_bucket/spirit76/Picture168.jpg

pretty well fried, really hard to get out of the mechanism due to the fusing of the plunger to the coil sleeve. ended up replacing the whole mech.

Heres one that was a bit less obvious:

http://i599.photobucket.com/albums/tt80/stuba_bucket/spirit76/xxxx.jpg

notice the coil winding that has corroded/broken under the plastic tab. I messed around a bit before I thought to test continuity of the coil (was actually testing resistance when I noticed there was no reading!)

Heres the playfield before the final clean up - notice the mis matched targets and crud

http://i599.photobucket.com/albums/tt80/stuba_bucket/spirit76/xx.jpg

there was another problem with the start button switch sticking on, caused some weird effects. dismantle and clean up fixed. I has some persistent score reel problems with the player 2 100's reel, it wouldn't consistently reset, it seemed the coil was not strong enough to drive the mechanism. I pulled it apart many times and even swapped coils, was getting ready to swap the whole unit out when I though to track the voltage train back to the reset relay - I discovered that the voltage went through a switch on the unit that looked ok but was a bit intermittent on continuity - i sanded the switch and increased the pressure and the problem went away - very handy one to remember.

so machine is all finished now, will take some final pics and post.

Nice work Stuba .
Sounds like a few tricky faults had to be sorted out .
Looks like that machine would have cleaned up a treat!
Look forward to seeing some pics of the finished machine .

Cheers
