1973 Williams Spanish Eyes Pinball Machine - EM Repair Part 2 - cabinet mechanics

ladies and gentlemen this is Joe's video games back with another cool arcade game video for you this evening this is not an arcade game though this is a pinball machine but pin balls are in arcades too so it counts this is actually part two of our series on repairing this Spanish eyes pinball machine if you watched the first video and if you didn't watch the first video go ahead and turn this off and go find it it's on our channel here but if you watched the first video we worked on the back of this game this is an old Williams 1973 Spanish eyes single-player e/m pinball machine and we worked on the back box so we we cleaned the score reels we clean the some some stepper units that were back there the replay unit and a few few relays and now we have moved on to part 2 where we are going to work inside the game a little bit basically trying to get the game up and playing and then we want to do some cosmetic stuff so I'm this is kind of a beginner's guide so if you're if you know all about pinball machines this may be really boring to you but if you don't know much about them hopefully this will hope you'll enjoy this this is basically the inside of the machine we've taken out the playfield sitting there as you can see there's just two jones bugs that you can remove just like the ones we cleaned in the back box and the entire play field will pop out and so you've got down here in the bottom a few things you've got a whole bunch of relays over here to the side a couple more back there you can see the sockets where the plug the jones plugs plug into i've cleaned all of the contacts on all of these this is the scorer motor very important you've got the fuses right here and then you've got a few more jones plugs over here and again we were talking a little bit about it whenever we're doing the back box but these things look much more complicated than they actually are they're very very simple it's just a ton of switches and so if you get all of the switches clean you get all of the the stepper units that we were working on in the back resetting like they should and stepping up like they should then the machine will work very well so now if you're if you're new to this I wouldn't recommend adjusting every switch I don't adjust every switch and I've been doing a for quite a while now if you if you see a switch that's obviously out of adjustment yeah you want to adjust that but you don't want to go through and try to make every switch perfect where you know you move this one a little closer or this one a little farther away because you're just gonna cause all kinds of problems for yourself so what I do is show you a couple of the relays just to show how the switches work and it just kind of it's it's like I said it's very simple and once you kind of understand how they work it really makes things make a lot more sense for you it took me a while to figure it out even as simple as it is it it doesn't make a lot of sense whenever you first start messing with these or and when you look at the schematics but if you start realizing that everything is on or off then it makes it makes everything start to come together in your in your mind a little bit so I figured we'd show if I can get it to zoom in on one of these suckers this here is a relay and it has a whole Bank of switches just like most games I mean just like most most of the switches are arranged in relays like this in pretty much any Union pinball machine and again you know this may or may not show up that well but basically what happens is the game tells this relay to energize this is a coil it creates a magnetic field which basically pulls this little plate in and when it does it connects the switches as you can see these some of these switches go through this little spacer here for this little whatever you want to call it and it makes the switches move so as it goes in you see the switches closed so let's look at this end one here I don't know if you can see the gap in it yeah there you can probably see it watch I want to push it in it closes the switch and if you look so whenever it energizes it closes it makes the two switches connect which makes to the two wires that are connected to the switches Connect and that's how the entire machine works so basically if you look really close the second one's a little better to see this one look this one if you look really close you'll see that when the switch connects when it connects it pushes the other switch just a little bit so you see the switch that it's hitting the blade move a little bit that's perfectly adjusted basically what that's doing is the switches hitting the contact on the end of the switch is hitting the other switch and it's making it move just a little bit and when it does that actually cleans the contact a little bit now I went through and cleaned all these switches with a small file if you do use a file you want to use one that's that's you know 400 grit or something like that you don't want anything really abrasive because you'll just eat up all the the contacts on the switches as you can see on the at the end of the blades you see the little point as they call it where the switch is actually connect you don't want to use anything really abrasive you want to use like a little flex tone or something like a really fine file just because you don't want to you know if you use a rough file you want to carve those points down to where there's nothing left so not all of the switches just connect like that where they're all where they're off and then now they're connected some of them are like this one on the end here this is called a make or break switch watch what happens when I see there's three blades watch what happens when I push this in basically the middle blade moves right now it's connected to the left blade and whenever it energizes it connects to the right blade and is no longer connected to the left blade those are the hardest ones to adjust basically it needs to be able to do both you know and it needs to be solidly touching the left one and then whenever the relay goes and solidly touching the right one and not touching the left one so you've got that style and then you've also got some that or if I can find one here here we go in this first relay here if you look at that second one if you notice it's already connected and whenever the relay goes in it disconnects it when a relay goes off it connects it and the relay goes in it disconnects it so it's normally closed and then when energized it opens the one next to it the third one there is normally open and when energized connects and then the one we were looking at over here on the end is a make or break switch it's one way when it's off and then it's the other way whenever it's energized so all of the switches and the Machine work like that and there's a ton of them I mean I don't know probably a couple hundred maybe a little more and this again is just a one-player machine so it's a little more simple so if you clean those switches and you get where the relay and again you get into you just press in on this little plate here and it simulates what it'll do whenever the electricity does it if you get it where they're all closing if they're open or opening if they're closed or making and breaking like they're supposed to everything will work great okay over here you've also got the score motor when these relays are pretty much the same on all of the games you'll they'll look a little different but they're basically they work this thing over here you've got the scorer motor this can be different on different machines but basically it's similar to the relays except the way it works is there's a motor here on the end that at certain times in the game will turn and whenever it does it turns this entire assembly here which has all of these different little cams on it and switches stacked on top of it so a lot of times if you get one of these old games and you plug it in it what will happen is this will come on and just keep turning and turning the turn Turner Turner Turner Turner you can't figure out what's going on with it basically it's trying to get back to its home position so if you look really close on this last one I believe it's usually called the index relay I mean the index cam this last one has these little points on it as it turns around every time it gets to one of those points it pushes the switches up as the little thing at the bottom rides up over the thing so right now the switch is these three or whatever aren't connected but whenever it goes up over that little point it pushes it up to where they're connected and so each one does something similar like this next one here and eventually it falls in a little hole there which makes the switch open and so each one does this so basically you have to clean all of these switches and you have to watch that action and go through manually and make sure that they're doing what they're supposed to do as it goes down do all of the blades open up as it goes up do all of the blades connect or however it's set up so yet another important part of the game and then finally what we'll talk about here in the inside are these fuses just simple glass fuses they're usually marked there behind it what the what amperage fuse is supposed to be in there you can use a fuse that it has a higher voltage because that's a rating so basically if you need a 5 a 5 amp 32 volt fuse might be something common that you see in one of these you can use a 5 amp 250 volt fuse because it's just saying that it can allow up to 32 volts too so if you use one that's a 250 it can allow up to 250 volts through so that's fine but you can't use one with a higher amperage so if you need a 5 amp you need to you need to find a 5 amp if you put a 6 amp basically it makes it harder for the fuse to blow and the purpose of the fuses is to keep something from catching on fire so you don't want to you don't want to put too high of a fuse in it if you go up a little bit you'll probably be alright but just as a general rule you want to stick to what it's what it's recommended to have and you see our jones plugs here i went through and cleaned those some of these are adjustments and things one of these is just where the coin door plugs in and then the back here this is an interesting a little deal again this is a 1973 Williams this Jones plug here goes to these two things this is the knocker which basically when you win a free game that flies up makes that noise and then over here this is the like a little chime box basically enough will fake it basically it hits this little silent phone bar here probably needs a little work but basically the little metal thing will hit the bar vibrate it and make it resonate in this chamber here so it's got that and we saw on the back how every time you score ten points it there's a little bar that hits a little bell in the back too so that's its mode of making noise for you so that's where we are so far what I'm gonna do next is I have this pinball play field here and I'm going to clean I just removed it because it's a little easier to work on I'm gonna clean the relays that are on it and I'm gonna clean the Jones plugs and I'm going to adjust a few things on the bottom of the play field here and then I'm gonna go through this reset bar here this has a relay be relay serie de lady relay relay number one relay two three four five and six this will be features that are on the play field I don't haven't even really looked into it yet but basically the way this works is this bar here will this coil will pull in which makes this bar pivot which pushes down all of these latches which opens switches and closes switches and then whenever you score whatever you score to make the relay pop it pulls in this little coil here's the one on the end the a relay it'll pull that plate in and will trip that relay like that so that will change the switches how they're now now they're touching something else buh-buh-bah so this is the exact same thing you just need to make sure that the switches are touching good and then opening doing what they're supposed to do just mechanically working so let me look at the playfield maybe we can figure out what those even are you've got numbers here so like there's a 5 a 1 a 2 1 & 2 a 3 & 4 and a 6 so whenever you hit that what it's gonna do is it's going to trip the corresponding relay and that'll cause different things to happen the scoring to advance things like that now the ABCDE relays I'm not oh those would be that to the top okay so here the rollovers at the top a b c d e so as you go through that roll over like this won't end e when you go over that switch the machine will tell the e relay to trip so one of these switches here on the e relay will like turn a white on or turn a light off and one will maybe set up another relay where now it works or whatever so all these machines are just switches arranged together that make wires connect the different things and you can see just all of the wiring that runs through them to make all of this happen it's a very it like I said before it's an archaic computer basically it's just a on or off all of these switches different things connected to different things very simple but really genius whenever you start kind of looking into the way that they were designed and the way that they work so what I'll do is I'll get started cleaning up that the bottom of that playfield and then I'll slide it back in and then we'll try it out be back in a minute all right folks we're back we put the playfield back in after cleaning some of the things on the bottom like I was talking about and I've got it plugged in something to turn it on and just see what happens yeah I guess if nothing happens I just won't upload this part of the video but we'll see so I'm just going to turn on the power switch first all right so everything reset to zero I don't know what that means and then I hit the left basically on the ODMs when you hit the left flipper switcher on a lot of them it turns on the attract lights the reason everything is blinking is because somebody has replaced all of the all of the the lamps in the back box with blinker blinker lamps they take 44 or 47 bulbs but you can put in I believe those are called mmm I can't think of the number right now there's a 455 I believe I believe the 455 bulbs you can put in and they'll do that they'll come one and then turn themselves off and come back on and turn themselves off so if you've got a bulb that stays on all the time like for instance this one right here you know underneath that plastic if you replace that with a 455 bulb that bulb would blink like these ones back here are doing right now a lot of times on the games I think they went a little overboard on this one but a lot of times on the games they'll uh they'll put the ones behind the title as blinkers and as you can see whenever that back glass lights up it actually looks a lot worse than it looks whenever it's off because of all the paint fading or cracking off all right so I don't know what's going on now it says tilt and it says balls to play too so we're going to hit the start button and see what happens well it went up the five balls to play like it should have and it reset the scores earlier like it should have but it did not kick the ball out we will that's that coil you're hearing is probably the match coil that was looked like it was burn up we'll see have anything spores Genesis balls to play five the ball just drained okay so it's not doing the game over so we're getting there so next what I'll do is I'll start trying to troubleshoot where we're at and why it's doing what it's doing all right ladies and gentlemen we are back we figured out our problems so the way you troubleshoot these whenever there's issues is you you kind of look at what is not working right and you then you look at the schematics and you see where that all joins together so there was a several things that weren't working right and then we were was trying to figure out what it could be and so I just broke it down so the first thing I noticed was that it did not kick the ball out into the out lane that's a common problem and there's a million different reasons why it would do that but basically whenever the ball ends on the switch that switch turns on what's called the out hole relay which is this one right here out hole relay and so by looking at the schematics I was able to see that basically the power gets to the there's a coil right here or it's actually right there right there that kicks the ball over and that coil was never firing so I looked on the schematics to see what makes that coil fire what makes that coil fire is the out hole relay so whenever you hit the switch the alcohol relay would pull in but the coil wouldn't fire and if you follow through the schematics you can see that it could be two or three different switches but I noticed that it was a there was one switch here on the relay that if I pressed it it would actually make the alcohol kick so basically what was going on was just that that switch wasn't clean so I cleaned the switch and it fixed that problem that was a really simple one so once I got it where the ball would kick out you may have noticed in the little video where I tested it that basically the the game would never end it would just play over and over and over and over and over again that proved to be a really tough to figure out problem took a couple hours to track down but I did figure it out just now so we're filming it to show you what happened basically when you got down the ball one and the ball ended it would kick back out into the outline and the game wouldn't be over so that you could play ball one over and over and over and over and over again and again this is gonna be different on every machine so you probably won't have that same exact problem but I just figured to show you what what the the particular problem with this machine was since you guys were watching to see what was going on basically here at the back is the game over relay and there's one well basically this is the latch relay it pulls it and latches it the game on basically and then this is the game trip relay game over trip relay so whenever that one pulls in it resets everything all that was working fine although the switches were adjusted right and everything but I noticed it on the last ball what was happening was this relay the last relay was pulling in and it was just holding the whole time making all kinds of noise that noise we were hearing in the video wasn't the burnt coil that we thought it was loose didn't get the focus it wasn't the burnt coil that we thought it was in the back apparently that coils just fine it was this latch coil right here so basically it was just always on and I noticed that whenever the ball landed in the out hole for the game to end the way that it ends is it makes this little trip relay go in which pops that forward which makes the game over and it was doing that but it wasn't resetting because this coil was constantly holding it in so another thing that was going on another coil that was stuck on was this replay unit that coil right there was stuck on which is the replay basically what did they call that the step-down coil I believe so it was stuck one and you could hear a clicking every once while click-click click-click click-click something a what in the world is clicking eventually I figured out that there is a meter in here that was actually clicking if I can find it I don't see it now but anyway so there's several little things that you know we were hearing and seeing well where do those all tie together so we looked at the schematics and let's see what we got here let me see if I can find it again so we can show you what was going on okay so right here is the game game over reset latch coil that was the one that was pulling in on the last couple balls right and then also if you go back it's fed by the coin release which on the coin relay well the coin relay was fine the switch wasn't connected didn't make any sense and then it connects over here to the ball count unit well all of these little positions are like this is ball zero ball one and then two three four five seconds well I was down on ball one whenever this was happening so it shouldn't have been connected so how was it getting power to the game over latts relay which was just staying on all the time it wasn't getting power through the coin relay and it wasn't getting MIT shouldn't have been getting power through the ball count you know because it was down over here it wasn't over here where it would be connected and then also we were getting a the game relay latched the one in front of it would come on and off and on and off and just doing crazy stuff this play meter was our thing that we were talking about clicking and then the replay reset coil was the one that was locked on so these three ross'll getting power and if you go back they're connected to the ball count unit through a finger right but the only way they should get power is if the corner he lays on and it was not checked it ten times just to make sure that switch was not connected so all of these coils were getting power somehow and it had to have been through the ball count unit and like I said it took two hours to figure out the game over reset latch was staying on but only when it was down here on like 1 and 0 it just it nothing made any sense you know so I will show you here is our ball count unit notice it's nice and shiny if you'll notice if you remember in our first video whenever I mess with that I said oh look it's stepping up like it should I bought this from a from a gentleman who had been working on it already and it went through and messed with a bunch of stuff whenever right now it's sitting on a I guess it's a little off but when it's like I can get it to step up alright that's own position alright so whenever it gets down to ball 0 or whatever it's like this and basically these two are connected together and these two are connected together and these two and this one are connected together but these two should not be connected to anything but themselves if you look in the manual right here this is a diagram in the manual and see how it says insulated so this goes to the hand you notice it's highlighted who ever had this before me already had figured out that there's something going on here so that says to game real a latch coil alright then over here on this side it says to game over real a trip coil to game over real a logical and I remember my latch coil was stuck one all the time what in the world is going on long story short after screwing around with it for a while I started noticing that there was a bunch of oil on this thing and this little spider here comes off really easily this little spider had oil all over it so what it was doing was it was making this top one here is grounded through the bolt to the machine right and the and it says in the paperwork see these it's right there it says grounded so some of the fingers are grounded but they've got this little bakelite see how they see how the fingers aren't touching each other inside of that they've got a little spacer there was oil all over it oil is conductive right so I was like man I bet that thinks shorting out so I took it all apart and sure enough on the bottom of it behind there it was all burnt up where that bakelite had already burnt apart because of the oil and basically this grounded one here was connected to here so go back to the schematics the ball count unit you see that's one place that there's the fingers so basically the game relay the game read you know game relay latch the play meter and the replay reset remember that kept sticking on while ever connecting over here to the ball count unit well it couldn't get power from this line through the coin relay so that wasn't where it was coming from and then did this ball count unit the GAMEOVER relay latch was sticking on it was connected over here but it couldn't have been getting power through these open switches that will relay the ball index relay but you know so that didn't make any sense why was the thing stuck going all the time so the one other place on the schematics right here the ball count unit and this is showing you the finger that's grounded kids look at this it connects over BAM so what was happening was my ground line was connected to the one set of fingers and then the oil was connecting this line to this line which was grounded to this which was keeping the game over real a1 and it was also connecting to this line which was coming to this which was making the game reset let's lock on the play meter like one on the replay reset line lock one so basically after I figured that out I took it all apart cleaned it a little bit like this that was burnt I cleaned it all of that off and then there was a little piece of missing so I actually put some hot glue down inside of this thing whenever I put it back together so that it it's not electrically touching and not conducting anymore so that fixed it up I will button this up and then we'll play a little game so you can see where it sits right now all right so I think we got most of the kinks worked out now again we're not trying to get it where it's like you know hundred percent ready to go I'm just trying to get it where it's working and then I can start doing cosmetic stuff and adjusting things and it still needs a ton of adjustments and things like that but at least now it's actually playing and starting a game and ending a game I also went ahead and set it on three ball just to just for now so I'll hit start and we'll see what she does or actually I think I need to add some credits yes that would help alright so we'll make sure everything resets and it does kick the ball out I'm on ball number three plunge it see if it score as well yep it's scoring again feeling some work oh that's cool you can go you can go behind the flipper Wow kind of neat can't play with one hand it's a cool little horseshoe shot there all right it's ball number two now ball number one the bulbs burn out so no big deal though get a lot of play on this one cuz of that pop all right game over cool all right so now it's working it's starting to game it's ending a game all of that there's still a lot of little things to go through but as we clean each part we'll go through and adjust things and things like that so the next video will we'll start in on the play field and things like that and do maybe a video on cosmetics and stuff like that so we will see you on the next video subscribe to us here on YouTube if you like this kind of stuff we usually show videos of our games whenever we get them finished and we'll do one of this one whenever we get it finished but we're gonna show repairing some stuff too we've got of course tons of games here in our shop that we're always working on one so we will see you on the next video
