Our BEST Schematics-Tracing Repair Video? 1973 Williams JUBILEE Pinball Machine w/Cut Wires!

ladies and gentlemen this is joe's classic video games back with another cool pinball repair video for you today we have been working on this williams jubilee pinball for weeks it seems like we've been doing other stuff too but we've been working on this pla this pinball on and off on and off we've about got it all done a lot of the cosmetics are done but the thing still doesn't play or at least it doesn't play right so we're gonna do a video fixing it so uh i also have not put the chime box in it yet it's sitting right there patiently waiting so we're not going to hear any bells and whistles yet but we're going to play through the thing and figure out what's wrong with it write it all down and then figure out how to fix it so when we last left the electronics we had gotten to the point where it will reset the score reels kind of so i'm going to turn it on we're going to see what she does and then we're going to write down all of the issues that it has and then we're going to look through the schematics and see if we can figure it out so uh if you like this kind of video make sure to subscribe to our channel and also give us a thumbs up for taking the trouble to film it for you right i usually say that at the end but half of the people that watch don't watch all the way to the end so y'all don't hear me uh speak so eloquently at the end of all these videos you've been missing out on so many good moments uh so let me get a piece let me get something right on i'll get my famous notepad and then we'll uh we'll uh start playing through it so i got our trusty notepad out these are our buddies down the road in gastonia they always bring us by extra notepads look at that i've had this one for a while it's the 2019 calendar he came in the other day and gave me some more new ones but uh i haven't got to those yet it'd be a tragedy if i used the 2020 ones and then in 2021 had to use the 2019 ones i mean i can't do that i got to use them in order right okay so when you have issues sometimes it's better to play through it and write them all down first because then as you go through some of them are connected together and it'll help you figure out what must be going on okay so we're plugged in the wall we're going to turn it on i got turned it off turn it on and then if you saw the one video on this particular one uh we already fixed where the lights wouldn't were always on you hit this button turns on the lights things starting to look pretty good really we had some uh we had some problems with some of the light bulbs up here that i've worked on the sockets and got them looking pretty good now one thing i see right off the bat that's an issue look over here the game over light is on but also the one ball and play light is on i'm checking to make sure that we don't have that we're not in the middle of the game that shouldn't be like that whenever it's doing that that's there's a there's something going on there so if we have more issues that may have something to do with it and one ball like is on you're probably gonna have trouble reading my uh chicken scratch but oh well people just deal with it so that's our first thing everything's reset back to zero because we were doing so much work in the back box and everything so i'm gonna try to start the game i set it on free play when i messed with it before so that's not an issue um so we'll see what that does just in this video i'm gonna talk about this little this little light here for you um we'll look this up too since we're messing with the schematics i had somebody ask me what is that little light for why in the world is there a little light there look there's one there this is also this is a valley instead of a williams ballet knight rider there is one there this is a stern stars it doesn't have one but since it's a digital machine it has the credit display on the back box we got some other ones here too i don't want to show you some of these yet though um yeah okay i got a couple other ballets sitting around that uh also have it why is that why is that uh light there why does it light up that is the credit light so the reason that they have that is if that light is on there is a credit on the machine now why do they need that whenever they have the credit reel in the back box it's old gambling stuff like a lot of these games were outlawed back in the day i've talked about this before and i could literally talk about it for an hour and a half but i can't get all into it right now but at certain points the pinball machines became gambling devices and uh they were they called them bingo machines and things like that and you would play for a nickel a round and you could win credits and then you could at some locations cash out the credits for for for money so the local authorities not really understanding what the difference was between this game and this game in this game in this game said if in some states in some areas said look if you can win a if you can win a free game on it or if you if they can cash out blah blah blah blah it's illegal and you can't have those so they made it where in some states in some areas it was illegal to show how many credits were on the game because if it said 10 credits on the game i could go up to the guy running the place and say hey i won 10 games and you know the bingos work a little different on the bingos you could win dozens of games in one game right but hey i won i won 10 games i want to cash out and they would hit a little button and give you your 50 cents but the local authorities just couldn't have that right so they said uh uh no no we can't have that uh there it can show that they're that the game has been credited up but it can't say how many is on it that way they can't pay you for that right and so they came up with the credit light so if the light is on there is a credit on the game which means that i can just hit start and the game will start but this one i don't think works right yet so we'll see if that happens but uh that's what that is for now since this one's on free play that light will never go off unless it burns out so i'm gonna hit start and we'll see if anything happens okay so see what's going on all the scores are back to zero something in the back box just keeps clicking and the score motor i can hear it turning in the bottom right so that's our first error so we are hearing the uh the score reset relays in the back going off over and over and over again so i'm going to write that down and then um we're going to look at that in the schematics real quick i would like i said go through and play more of it and write more stuff down and then do it all at one time but it won't even kick the ball out right now so there is an issue so we'll figure out why it's doing that okay folks so here are the schematics got a nice printed copy so i checked in the back box and confirmed that there are two relays in the back bars going crazy and they just keep going and keep going the score reels are just sitting there not doing anything so why is that happening those are the two score reset relays now keep in mind many games do this differently we are working on a williams so all of the williams games from this era will have a similar setup but the got live ones will be slightly different the valley ones will be slightly different so if you look on the schematics how could these possibly help us figure this out well what we're going to do is we're going to look for what we know like what do we know so far we know that this 1 2 reset relay and this 3 4 reset relay keep turning on and off on and off on and off that's what i'm seeing that's the noise we're hearing and we know that this score motor keeps running right so these three right here just keep on going okay now why is the score motor staying on right it's because the score motor will stay on well we're gonna have trouble with the focus on this i think if any of these switches are on the score motor will be connected to power on the transformer so that side is always connected through this fuse right so that side of the motor always has power this side of the motor connects to the other side of the power over here through any of these re of these switches so if any of these switches are on that motor will run so the 25 cent relay uh the three advance relay the shooter relay the coin relay that's actually a switch on itself will hold itself on right so the score motor will keep keep itself on until this switch opens up on itself that's how it stops at the same place every time the coin relay will turn it on the out hole relay will turn it on the bonus relay will turn it on the 50 point relay will turn it on and that's it okay so if any of those uh are running it will just keep running now why am i not seeing the reset relay shooter relay coin relay out hole relay bonus relay it must be coming from over here there's a switch on the reset relay right all kinds of stuff so look at my focus so we know that that's staying on and we know that the one to two reset relay and the three to four reset relay are staying on so what turns off the one to two reset relay and the three to four reset relay right well the reason that they're firing over and over and over again is because they're on the impulse cam of the score motor so as the score motor turns it connects this line to that line and powers both of those relays and that's exactly what's going on so there's two different switches on the impulse relay i mean on the impulse cam of the score motor that are making it do that so how does that get power well you're working back this way it gets power through the reset relay so if the reset relay is closed see how there's two lines but no dash through it that means normally open so when it's not energized when the power is off that's normally open but if that relay is closed it's sending power up here and then the impulse relay as the score motor turns is sending power to those that's what's making it click click click click click so the reset relay must be on or the switch is stuck but since we're starting the game and that involves the reset relay obviously there's an issue there all right so through the reset relay and then through the drum unit zero position brake switches all right then it says 16. so on each score on each score reel there is a switch there's 16 of them when the drum gets back to zero those switches open up and so as long as one of those is closed right power will connect from here through whatever one of those 16 switches is closed or all 16 of them right through them through the reset relay which is closed up to here through the impulse as the score motor turns around and make those click click click click click click click so what is the easiest explanation one of those drum units must not be getting to zero right so since one of those isn't dropping to zero that must be our deal but then we also have this situation where the reset relay is held in so we need to figure out what makes the reset relay turn off let me see if i can find it on here it wasn't hard to find the reset relay it's right next to the 1-2 reset relay and a 3-4 reset relay and it's powered by the same exact power so the way that turns off is see what's going on is it's everything's starting and it's pulling the reset relay in which is holding itself in and it will continue to do that until all of these drum unit zero position brake switches open up so all 16 of those have to be open at zero for that to kill the power through here to the reset relay so that's what we need to look at first we need to see if one of those drum units isn't getting back to zero or when it's at zero if it's not opening up so we're going to look at the color of the wires this wire down here is yellow and then it goes to a blue wire with a brown trace [Music] so we're going to find that in the machine on each score drum unit and we're going to pull them all out one at a time until i find the one that's still connected even though they're all at zero okay folks i looked at all 16 score reels and it's the top switch on each score reel none of them were misadjusted which makes sense because i just went through them all anyway so i was hoping i missed something but i did not so when i take my multimeter and i check it checks as if they are as if they are connected right like one of them shut if you if you look um where are we at so we're right here if you check this wire the yellow wire to this wire on the switch on any of them it says it's connected because if any one of these 16 were connected it would be connected but they're not so what could cause that it could be a shorted wire or something like that remember we replaced all those wires on the uh in the cabinet [Music] hopefully it won't be one of those [Music] um but if you look if one of these other two ways of getting power was also getting power it would do the exact same thing so it could be either one right so we're gonna ch oh and and what i did was i unplugged the back box and uh it was no longer shorted which could still be one of the wires we replaced [Music] okay um so we're going to check that but there are two other ways for to get power it could be the bonus relay has a switch on it i looked at that and it's not connected and the bonus relay never comes on because the bonus relay comes on whenever the game resets to reset the bonus unit well it's reset all the way the only thing that's still running are these two reset relays and the reset relay right so it's kind of one of these three power sources has to be still giving it power and i'm thinking it's this index switch so on index e there's a switch that's yellow and blue and brown that also sends power up there right so here is the schematics of the score motor it's also on the on the thing and the the different cams are called different things impulse forward the impulse cam five four three two one and the index cam switch e on the index cam is the top switch i'll show you all this here in a minute which is the reset relay lock switch that's what we're looking at right so it's the yellow wire and a blue and brown wire so there is a switch here that as this turns around whenever it lands in this valley it should open up that switch the top switch should open as it lands in that valley so back to the play field trying to look at that let me go show you what we figured out okay when you're troubleshooting this particular game there is an issue with this thing in the middle when you lift the playfield it makes all of the balls that are in the middle on these switches slide back here to these switches which are the ones that score and stuff so if you lift the play field the balls go back here and the bonus unit locks on which can burn up the coil on a bonus unit and everything else so if you're going to be doing a lot of lift in the play field while it's turned on you kind of need to take those balls out so they don't roll around all over the place so they're over there waiting for us right so that cam that we're talking about is right there it's the first one right and it's the top switch on that can okay so let's see let's see if it's an intermittent thing or if it's still going to do it we'll try to do it and reset it again okay so it's still running right the bonus unit is not coming on because you don't hear the bonus unit that's up here on the bottom of the play field clicking it's just those two reset relays okay our next clue is if you kick the ball out or if you take the ball out of the play field score motor stops hmm hmm all right so we're gonna and so now we're at ball one flippers are working which is the surefire sign that you are in game play uh okay so if the ball comes out of the ball the out hole um score motor stops so that what's going on is it's trying to shoot the ball out of the out hole and it's not being able to so we need to figure out what that deal is we're getting farther along so i have figured out now right that if the uh if the ball is out of the shooter lane i mean it's out of the out hole it will it will do its thing so we're still in our game over in our one hit start sometimes it just goes to game over now this is with the ball out of the out hole sometimes it will start a game right but as soon as the ball ends in the out hole it ends the game the ball and play one light uh over there is actually always lit if you're on ball and ball number one it doesn't turn off the only thing that turns it off is it tilt okay so something is making the thing immediately go into game over if the ball hits the uh if the ball hits the uh out hole swoop so we got to figure out why that is it must think it's the last ball or something okay folks i said way back in my first video when i was working on all of these wires that got cut that some of them are the same color and should i trust that the guy put the right ones back together okay so as i look i see two that are blue with a yellow stripe there's one there and there's one there right and i see one that's blue with a red stripe right there and there's a blue with a black [Music] there's a blue with i guess that's a brown and then over here is another blue with a red so there are two that are blue with a red stripe that are identical they look exactly the same trying to decide if there's more than two right you see where this is going right uh we're looking we're looking i only see two [Music] okay let's look at the schematics so when the game starts it immediately trips the game over really or sometimes it'll hold on until you hit a a score or something and then the score motor turns and drifts the game over really look what color the wire is that goes to the game over relay it's blue and red and see the little four next to it that means there's at least four wires that's the fourth wire in the game that is the exact same color okay now this blue and red wire runs over here and it runs to the player unit zero brake switch the player unit is in the back box the game over relay is in the cabinet in the bottom so there is a blue and red wire that trips the game over relay that runs from the zero brake switch in the player unit all right connects down to here so the the other side of the player unit zero break switch is blue and yellow the fifth one of that color and it connects down here through the coin relay so the reason it does that is so that if you put a coin in it pulls in this switch which sends power up and if the player unit is not on zero so if it's past the first player's first ball basically this will close after it gets off the home position so it would send power through and trip the game over relay so that it restarts the game when you put a coin in if somebody has already played part of the game do you understand what i'm saying so if you put in a quarter let's say a quarter i don't know what coin it is but you put in a quarter it starts a one player game and then you want to play two player game you put in a second quarter well if you haven't done anything that player unit is still the zero position the switch is still broken also the ball count zero position you know but that's in the bottom of the cattle we don't have to worry about that so this player unit gets a blue and yellow wire to it and then a blue and red wire comes out of it and goes down to the game over relay that's how it's supposed to be but there are more than one blue and yellow and one and blue more than one blue and red okay so if you go over here the same player unit that's in the back box has a wire that comes up from here so the out hole relay the extra ball relay the ball index relay sends power over to this motor switch in the bottom of the cabinet and then it sends power up into the cabinet to the player unit on another blue and red line and then the blue and red line not only feeds the player unit which is in the back box but it goes down to the coin unit which is down in the cabinet again so you've got a blue and red wire here attached to the coin unit um and attached to the score motor okay so when you start the game the score motor is moving which means that switch is gonna close eventually which would send power through that blue and red line now if i was to have that blue and red line hooked into the wrong thing my brother donnie's calling me if i hooked it wrong it might at a certain point send power over here to this blue and red line if i've got a hook to the wrong one which is directly connected to the game over relay right so i'm gonna swap the two blue and red wires and see if that fixes it i think he's got him backwards but i don't you can't really tell everything's bundled up you can't really tell what's going to what you know i'd have to take the whole loom apart i guess i could use a multimeter maybe i'll multi-meter it a little bit i think the two wires are backwards that's what i think okay folks another hour and a half has went by now i can't film everything i'm doing because it's boring so i got to tell you what i did instead of showing you 30 minutes of me going i wonder what this does oh let's touch this no that's not right what color was it uh well let me go back uh um uh right so i know we're not showing too much of it but it's because i haven't found anything but i have found one thing i want to show you something i use the multimeter on the actual jones plugs right so there's two blue and red pins on the jones plugs that are running to the top we figured that out right so they're both connected where they should be the guy did not mess up the blue and red wires so it was a great theory but i was wrong so i'd like to apologize to him he did a really good job of getting the blue and red wires together so we'll see what the real problem is right um let me show you something else i found i was thinking you know that's got to be it hot damn and unfounded but i couldn't quite figure out why connecting the blue and red to the wrong blue and red would make it go to the game over thing right i couldn't quite couldn't quite get my mind around it and then i noticed that the blue and red also connects to the three and five ball adjustment jack now i haven't watched the videos like you guys have because i've forgotten a bunch of what i put in the videos but didn't i play it or something didn't i already shoot the ball or something i can't remember if i did that earlier or not but i thought i already played this game a little bit and it was doing more than it's doing now so i couldn't figure it out and then i saw this the blue and the red connects so this wire comes up and depending on where you put the adjustment jack it changes it from when the ball count unit gets the position three which is ball three it connects this wire to this wire if you're in the three adjustment which trips the game over relay or if you're plugged into the five adjustment uh it doesn't it's not connected to anything so you set it on five you just plug it in it doesn't actually connect to anything but whenever the ball count unit gets up to here there is a wire here that's blue and red that trips the game over relay so that's how the ball count you know when it gets to three four see they've got three and four tied together just in case it screws up i guess but it's how it's how it knows if it should uh trip at three or five the game over right but remember ours is always on one so i looked over here and ball and play light one if the ball count unit is in that position that light will always be on unless the tilt relay clicks there's nothing to turn it off right so the way you get that light to go off is you count all the way up to i guess past five it'll do it or something i don't know maybe it never goes off whatever so but we know we're in position one we're not in position three we're not in position four and we're not in position five so that can't possibly be tripping it okay but look at this game over relay trip wire the ball count unit is in the bottom of the play field and the wire coming up for the three thing is blue and brown and there's four of them right blue and brown well if i did play it earlier i set it on three ball whenever i did the back box because the jack the adjustment jack is in the back box and i remember moving it from five to three now it don't play right so i went back and looked at the blue and the red and that is the jack is a blue and red wire but it's fine there's nothing wrong with this connected to the right spots on the jones plugs and the jones the female part of the jones plug so there is a blue and brown wire that comes from the bottom up to the top to the adjustment jack all right we got to brighten this up this is going to be our thumbnail now you guys saw the thumbnail when you clicked it but did you really look at the thumbnail so that is a blue and brown wire connected to a blue and orange wire and this is a blue and orange wire connected to a blue and brown wire why in the world would they do be like that first williams did me like that and then the jackass that worked on this game did me like that okay folks i've calmed down a little bit so it's not really the guy's fault right it's whoever cut the head off the machine's fault somebody was making the point that the guy that cut the head off the machine may have not been the guy that taped all of the wires together i understand so i'd like to apologize again the guy did get the blue and red wires right but he got the blue and brown ones wrong and the blue and orange one's wrong and then i came along behind him and all i did was take his wires and just change the connector i didn't swap any of them or anything so as i look around i think what's going on is that one that's blue and orange it looks a lot like blue and brown so it's really similar so i mean it's really hard to tell it apart but here's here's the deal okay let me show you what the the two blue and brown ones i found go to remember earlier in the video when i could not figure it out and i was saying damn it doesn't make any sense what's going on maybe if we wrote more things down they're all related but i can't because it's not even starting the game remember all that right let's go back where we was the one and two reset relay the three and four score reset relays are in the back box okay they get pulsed by an impulse thing in the in the bottom of the cabinet right okay and then how do they get their signal they get it through the reset relay and then through these drum unit zero position brake switches that we were looking at first right and i said damn it's like they're connected but they're not connected it's a blue and brown wire so there is a blue and brown wire that comes from the reset relay in the bottom of the cabinet up into the cabinet and connects to the drum unit zero position brake switches all 16 of them and then a wire that comes back down that's yellow that connects to the yellow wire in the in the bottom of the cabinet okay so this is this must be the other wire that looks weird that we can't figure that looks like blue and orange or whatever right so it's this is com this is complex to even understand but yellow aground is coming up into the cabinet right and then going to the switch on the all 16 of the switches on the drum units and then there is a blue and brown wire coming off of the drum units that's going back down into the cabinet about right here when it does that it's going to the wrong switch it's connected to the wrong wire i mean so that wire right there is now connecting since it's backwards to this wire that is coming from the ball count unit blue and brown up into the top of the cabinet so about right here we've got that wire off of the off of the uh uh drum units that are all open connecting to here it doesn't do anything right now i've got this wire connected where this one is supposed to go so this is cut about right here but notice how they're all tied together so it's also tied to the bonus relay which is actually on the uh i believe on the play field but it's also connected to that index that we were looking at index switch that's why whenever it goes up we're seeing sparks and everything it's because this power so power is coming through here this is yellow it's coming through here and then through the switch right and we're getting we're getting all of this reset relay must be doing this thing and everything then it's circling around and instead of going up to the drum units it's plugged into the wrong wire in the in the head and it doesn't connect to the switches on the drum units so we got ground right this is neutral basically it's ac coming up into the head and then it doesn't go here where it's supposed to it goes here because these wires are swapped so now i've got ground through the plug to here to the three to five ball adjustment jack i changed it over to three which plugged it right into the game over relay that's how you do it folks that's how you do it you see here how the wires are actually completely different but they are both technically blue with brown just like just slightly different though they just look like one of them looks more orange than the other one crazy all right so i'll swap them if i haven't got them confused and we'll try it okay folks i swapped two wires i put a heat shrink on it plugged them back in now let's see what we get lights are still turning on we still got the one ball game over thing but we're hoping that now it will actually start a game is there any better sound in the world than that it doesn't say game over yet remember there's no no uh chimes in it yet oh hell ball two wow i think we fixed it now i'm sure there are many other things screwed up that i don't know about yet like for instance the third ball and play lights not working but we are scoring but this one was a lot of trouble i don't have the balls in the middle yet either i guess i didn't score that last time so it didn't take the ball away from me game over after three balls it was four balls but i think that one i didn't score anything but this took so much time just figuring out why the thing wouldn't start and it was such an interesting fix that i figured it could do its own video so we'll do another video where we do the chimes and we do all the schematic stuff or whatever else is broke on it and that'll be tomorrow's video so leave your comments below let us know what you think make sure to give us a thumbs up for taking the trouble to film it and for sticking with it till we figured it out isn't that the best part about it if you can't figure one out folks just let it sit for a while go back to it you'll figure it out eventually it's always something leave your comments let us know what you think we'd like to thank everybody for using our amazon links people bought all kinds of stuff for christmas boy that was pretty cool of y'all so if you don't know how that works there's a link down below to amazon if you're going to go to amazon anyway it will uh give us a little tip for anything you buy on amazon because we sent you there so thank you to everybody that's been doing that and also make sure to check out my brother's channel my brother donnie he can be your brother too i already asked him he said that was cool so go check out my brother donny he's literally my brother he's always doing something crazy recently we bought this little tiny building it's an old dilapidated building and it was not expensive but we did buy a building that used to be an old grocery store a little tiny one and we've been fixing it up and we're going to rent it out and uh so we've been doing that over there that's pretty fun if you like seeing old things fixed up you might like that channel too donny's pretty wild and crazy that's another thing i want to mention whatever i'm going on and on about the guy i'm just having a good time playing around people i'm not really bad right um it's you know every game has problems with it but what i want to say is the guy tried at least right now i i think they're probably right somebody cut the head off probably sold it to somebody else and then the other person tried to put it back together didn't get it because he missed one freaking wire of course there might be more but we'll figure that out in the next video i guess but at least the guy tried right don't give up if you've got something like this you're working on you can figure it out eventually i didn't figure it out because i'm a genius i figured it out because i keep freaking working on it just keep at it and you'll get it you'll figure it out and it does all make sense once you figure it out none of it made sense at first right we're going what the world when it makes noise why would it do that that's that's crazy i don't understand it should be this but it's not what in the world and then finally we figured out what it was and it all made sense it's both of the problems were the same thing right so just just keep at it and uh you might be able to find an old beat up game near you and fix it up that's what i'm hoping these videos will inspire people to do people have asked us oh are you going to lose business because people will figure out how to work on a pinball machine believe me we got plenty of business there's only a couple it's me and joe we're working as hard as we can fixing the stuff we've got and the repairs people are bringing us so if you can find one near you buy it and try to fix it i hope i hope people do so that we can save more of them so leave your comments below let us know what you think and we will see you on the next video tomorrow hope you enjoyed it
