You're like a pit-bull when you get your teeth into arcane details (300 vs 3000). I love it!
Gotta figure this stuff out :)
everytime I watch your videos, I gain learning that I didnt have previously! we thank you for your dedication to an appreciative audience!
Thank you Trumps Turn! I appreciate you watching buddy.
Recently bought a well-used Captain Fantastic machine. I replaced all the rubbers, burned out lights, fixed some mechanical problems and cleaned it up, but couldn't get it to play. I'm a pretty fair tech, but got nowhere with it until I watched one of your videos. You mentioned cleaning all the contacts (a 3-hour job), so I ordered a pair of contact burnishers and went to work. Bingo! It's working about 95% now, with just a few minor glitches. Thanks so much for your great tutorials.
If you rebuild those steppers it'll probably get that last 5% for you, those things need to step up and down reliably that's one of the main issues with them.... glad though you got it back amongst the living, that's a great game! Hell I like Elton too.
Wow did not no pinball machines was so complicated I have trouble with my lawn mower good luck loved the video I don’t know why l watched it Darren from Australia
Joe your dedication and commitment to the gaming industry is beyond words, that was an outstanding tutorial and thanks.
Aw.... shucks....
Watching your video's has help me alot especially on reading the schematics.
Thanks for this video. I have an old Bally Trio. I also have the full schematics, but I couldn't figure out how to read them. Now I feel much more confident tackling all those relays and switches.
You can do it man, once it starts 'clicking' you'll see how simple they really are. It looks like there's tons going on but really just a bunch of switches going on and off.
Thanks Joe! I’ve had a busted Gottlieb Aloha for years, and this inspired me to actually figure out what’s going on.
That's a cool game, you should be able to fix it if you work through it a little bit!
You've earned my respect and subscription of this video sir! Awesome job describing and guiding through what you were checking
logically.
Great video! I learned a lot, thank you! I own a Williams Grand Prix. This'll help me make sense of the schematics!
Great video. Thanks for walking through the schematic with us
No problem Benjamin thanks for watching!
More schematic work, I love it!
It's the most fun part of it....
Thank you so much I'm planning on getting into pinball repair as a hobby. This is a great head start.
Very cool, the good thing about the older ones is they don't cost much to fix!
Very cool video. This is the first video I found of yours and you immediately had me hooked. I subscribed right away. I have never owned a pinball machine of my own, but have played them since the mid 80s. I've been thinking about buying one, but was nervous about having an issue with and not knowing where to begin to troubleshoot. This video, while specific to this machine, was very helpful in seeing how someone goes about the troubleshooting process. Many of the videos I've watched from others simply said, this wasn't working, so let's fix it, and then they go right on in to the repair, but never said how they knew that was what the issue was in the first place. Very much looking forward to binge watching your videos - you have a lot of them :-) Thanks again - Chad!
Thanks Chad, glad you enjoyed it... we do repair videos all the time and we try to get pretty pedantic with explaining it so that even beginners can know what to do. We figure if somebody knows how to fix them already, they wouldn't be watching our videos anyways :) Hope you enjoy them, see you on the next one!
Not just in this video but in all your schematic videos you explain very well. I'm an electrician by trade and deal mostly with building automation and temp control. I have to read ladder diagrams but pinball schematics are quite a bit different. Your videos have helped tremendously. Thank you.
No problem Ryan glad you could use the info, im' hoping it'll help others fix their machines, I can't fix but a couple a month so there's plenty of broken ones around for everybody :)
@@LyonsArcade if you ever mess with a bingo please share. Those are different animals.
helpful, as a new owner of 1976 Freedom machine and no previous knowledge of reading schematics before this video gave me some help and confidence at working on my machine. Luckily, a lot of things work right but its not perfect and i'll be trying to figure it out on my own. thanks
Very cool George, just remember when the relays pull in it always opens the closed ones and closes the open ones. Once you understand that simple part it all makes logical sense, it just takes awhile sometimes to figure out what it's trying to do.
Joe you are one smart cat. thanks for all your videos i always come back to this one when i am stuck. on something.and it always sets me back on track..
Aw shucks. I'm glad I made it easy to follow hopefully it helps somebody!
Best video I've found so far!
EM troubleshooting is a lot of fun.
Yeah, I'm having... 'fun' right now trying to track down problems in my Space Odyssey. Video soon...
I just found you, wealth of knowledge, very helpful
Glad to have you here, Starguy9!
Great video. I worked on all types of arcade games before but I never had an opportunity to work on EM types. Thanks for explaining how they work. Now I feel confident enough to take one on. Also, I noticed a table in the schematics. Maybe that explains the scoring.
The table shows the switches that are on the score motor, the main part down in the bottom.... there's so many of them they put it in a table so it's a little easier to understand which switch is which. Thank you for watching Isidro, hope it helps you get an EM running one day :)
Reading pinball EM schematics got me started in the field of electronics. Can be complicated but very basic. The score motor switches are the worst to get at. Thanks for uploading!
Absolutely. They're kind of hard to see, have to really get in there! I try to not even adjust them, assuming most of them are probably still adjusted right and just try to clean them with a little flexstone or something.
Thanks for the vid, i really like these old EM's. Maybe add Kick off to the video title, so others can find this one easier.
Thanks! I'm going to do a separate video just for Kick Off, this one was more about how to fix any Bally EM through the schematics.
Joe
I just finished watching your how to read pinball schematics on a 1975 Bally EM pinball machine.
I attached a couple photos of a rawhide game that a dirt bike bike riding buddy dropped off in my shop. This is what I get for being a retired maintenance Electrician and giving him the combination to my shop.
I need prints and parts.
The rotary switch turns 1/3rd of a rotation every time the credit button is pushed or the coin limits are flagged. The game over light never turns off and none of the scores reset.
I must apologize to you up front I have never played one of these. I have no idea what a 3 ball or 5 ball is.
When I had a quarter I bought a corn dog. Almost 63 years old, at any fair, first thing is a corn dog. I follow the wife until it is safe to ask if it's time for another corn dog.
Thanks ahead of time.
The photos were attached to an email.
ah man, my first EM pinball was a slap stick. that thing was fun as heck in getting all of the contacts adjusted without a schematic.
Yeah it's kind of a mystery to solve. I'm working on an old Williams EM right now with some gremlins....
very helpful ... thanks a lot !
Thanks for watching Chris, hope it helped :)
Great video. Learned a lot how these things work
Cool Ron, now it's time for you to get 1 and save it :)
@@LyonsArcade wish I could. They cost killer money around here. Maybe one day if I run into a deal.
Around here you can pick up a broke one for 200 or less usually. There's one on craigslist right now for $125 nobody's picked up yet, and we bought one a few days ago for $100. There's tons of different games out there, remember before about 78 all the coin op games were basically pinball with a few exceptions... so for about 30 years they just churned E.M. pinball machines out as fast as they could build them! We're working on a 1956 Gottlieb right now, pretty fun stuff.
@@LyonsArcade Are you kidding me!!! Man I wish cheapest I've seen is $950 for something OLD..... My wife would kill me if I lived there hahaha I'd have them in the living room!
Nope, not kidding. That's for something broken that needs work, but these old EM's usually don't need many parts, just a lot of cleaning and tinkering.
learned lots from watching this video. thanks
No problem Egg, glad you enjoyed it!
Always tighten the switch screws then clean the contacts before anything. #1 thing to do. On the score motor and the relays in the back score motors. Also make sure they are clean and lubed. It will clear most problems.
I just picked up a Bally Wizard. I'm pretty sure this video is going to go a long way towards helping me get it running :)
That's a cool game, looks great too! It should be very, very similar to this video, I think it's only about a year and half different.
Two clips that hold fuses in are broken. I'm hoping as soon as I swap that with some from a parts machine, it'll just start right up. . . yeah right lol.
Thank you again for another great video,and giving me the strength to stay away from EM machines and stick with SS machines! Lol..I now see why no one works on these hardly. Great when working, but. Hell on wheels to diagnose and keep running.
Once you kind of get into them a little bit, they're really not that bad and the good thing is it doesn't cost hardly anything to fix them :) Thanks for watching Metal Justice, we appreciate it!
This are the true pinballs. The electro-mechanics. I love this old machines- Gottlieb´s Fast Draw, Royal Flush or Spirit of 1976. Not the CPU-shit.
Preach, brother
Very informative for me, thank you! Any recommendations on how to learn more about reading schematic charts? Thanks again for your advice and assistance in helping me remove my Gorgar backglass!
You just get an understanding of them from practice, after you work through some machines a few times you get a little better at understanding what's going on. Everytime I do an EM repair video I try to show my thought process working through the schematics too.
Wow
I've played with one of these.
They're fun to tinker around with!
The 3000 points come from the soccer ball lit up below the playing field which was on 3000 at the time. The amount would vary depending which light below the playing field is lit.
That makes sense!
Super interesting stuff here! I'm just about to start working on my Chicago Coin "Jukebox" pinball and I'm at the same place you started at: I get lights on power up but it does nothing afterwards. The schematics written for Chicago Coin games seem to be a lot more confusing, or maybe I'm just an idiot lol I guess I'll start with checking the fuses and then cleaning the relays and making sure they're all adjusted correctly and go from there.
You're not an idiot it's just in a different language. Once you start understanding it, you'll kind of get there.
It's just fascinating the things that could be accomplished in the pre-microprocessor age by purely mechanical means, if you had enough brain-power to design and build it. Certainly this pinball machine, but also fx. encryption devices (the enigma), etc.. Appreciate the thoroughness you put into this. If the video is 30 minutes, the effort put into actual restauration certainly justifies a "certain price". Thanx a lot for the vid!
Thanks! Yes, it always blows my mind what they could do with just switches and motors.... we had one a few years ago called "Hotline", the game actually spelled out "Hotline" on a big grid in the playfield, once you completed the "H" it would turn into an "o", then after you rolled over all those targets, it would light up "T"... etc. etc. one of the most creative uses I've seen so far on pinballs.
Absolutely! It's just all doing it inside the chips :)
I've never worked for a huge corporation, any chance of you getting back on board if they ramp up production in the U.S. like they say?
I'm with you 100% on all of that, the world has gone mad. It's reached a tipping point, where more and more people are standing up to fight it but that doesn't do anything to fix what's already happened. Sorry to hear it went down like that, hope you were able to land somewhere else or they paid you enough to make up for it!
"Older white guys no females and very few minority," maybe that's because they didn't hire females nor minorities before. Thank god they are now. You can do us Californians a favor and move to Florida.
Joe- special thanks for the schematic tutorial. It is very helpful, even though I have a degree in electronics, some of these schematics use some archaic symbols for switches. Do the schematics usually have a schematic symbol definition chart? Keep up the great contributions to the Pinball world.
I don't think I've ever seen one with a chart unfortunately. They all are pretty similar and only use a few symbols, so you have open switches, closed switches, make or break switches (which is just both of the others at the same time)... a motor, a bulb, and a coil. The open switch symbol looks like a capacitor symbol.... and in the few instances that they use capacitors or diodes they're pretty well marked. Once you figure out that everything is just switches and coils and bulbs it is a lot simpler to understand. I guess the stepper units are a different symbol too.... basically it just shows each connection point on the stepper and then an arrow that represents the connection that moves from connection to connection as the stepper spins.... The position everything is shown in is always in the 'off' position or home position.
I love all the schematic reading, explanations. Of what it should do. Trouble shooting pinball games, as everyone else does too. Thks for all the time spent.
Did you ever think of doing videos solely going through schematics, &
explaining each circuit , maybe using a matching power source or jumper wire of connect power to
make things move of what something does if energized. After reading a circuit.
I started thinking about this because there is nobody doing it. You go further than anyone else
I think anyway. With schematic reading. But I don't thing there is anybody dedicating them selves,
to the subject. And nobody explaining schematics for pitch and bat games for any company.
They always say buy norm and shaggy's video but they talk about more body work on the machine.
And they don't touch on chicago coin . who built at least 27 baseball games. of coarse a baseball , game collector would have to train us as they own the games to us for tutorials
JOE CLASSIC, When looking at various EM schematics if it didn't tell you how could you tell if the EM schematic was drawn in "Reset Position" or in "game over Position"? some EM games are drawn in Reset position while other are drawn in game over position so it gets confusing when looking at the various closed switches and open switches.
Awesome, thanks!!!!

Thanks Ono, we appreciate you watching!
Damm
I saw a old pinball machine behind a bar in the alley, I was buzzed but I remember the name was subway.
Gooooaaaallll!!!
LOL
Hello Joe.
Love your video.
Love the way these EM's were designed.
I understand that EM's use straight AC. What I'm a little confused about is the WAY they use AC.
I understand electricity, as it pertains to residential wiring. You have a hot, and a neutral.
Does that same principle work throughout the machine's devices? I'm seeing the hot run through
to each device, but not seeing a neutral. If the neutral keeps the load balanced, like a parallel
circuit, then what happens to the neutral, once power is supplied to the cabinet?
Thanks for taking the time to educate us. Appreciated.
I'm HORRIBLE with understanding how AC works... but it uses AC that's ran through a transformer so not sure if that changes the way the AC works, but yes it's still AC. Basically the whole gist of it is, each coil or relay has two wires going to the lugs, one is always on (which would represent the hot) and the other, when connected, makes the relay pull in or the coil pull in. So the entire game is designed by having switches placed on the one side as you can see in the schematics, when that switch is connected it pulls the relay or coil in, when the switch is open the relay or coil lets out.
The genius is just in how complicated they get with it, but ultimately it's always just switches and coils! There may be 15 switches that the voltage has to run through before it gets to the coil, but if all 15 are pulled in it works.
Essentially it works exactly like DC voltage does, at least in the pinballs. Not sure if the transformer makes the AC work differently and that's why it works... but basically the arcade games work the same way, they just have a DC power supply in the bottom the AC turns on.
Joe's Classic Video Games A transformer does not change an A.C. current to another type current or DC.All a transformer do is that it converts an A.C. voltage to another AC voltage ie for example you feed it 110v AC and it converts that voltage to 12v A.C..
Ball's bingo' s worked on 50v A.C. so a transformer was used to lower the 110 or 220v A.C. to 50v AC. DC power supplies also has a transformer to lower the A.C. voltage first and then this voltage is feed through a rectifier to convert it to a DC. Goodbye.
Joe's Classic Video Games typically there will be three levels of voltage in an EM pinball: line voltage, coil voltage (25 seems to be typical for EM, was unaware bingo machines use 50V), and lighting voltage (typically 6.3V).
時代が感じさせますね 本当に ピンボールは おもしろさが 偉大ですよ
はい、彼らは非常にノスタルジックです、あなたは彼らの歴史を感じることができます！

Hello can you tell me where i could get schematics for a bally Flip flop em machine ? Love your explanaition learning Every day
We always get all our stuff from pbresource.com , I don't know of any place to download them so you'll probably have to buy a copy. See you on the next video!
on this Bally Kick Off that you are working on.your schematics look to be on a monitor.etc..did you just scan them in and then work off whatever type of file you saved them as??
Hi Steven! You can download tons of schematics for free from www.IPDB.org go check it out!
Totally get it, and i find it easy.:) Do you have any idea, from where i can get an electrical planning from a Bally Galaxy '78? Tomorow i gonna buy one, just they don't have any documents for it, and with a plan saves some time for me.😁
Not sure where to find one online but I believe you can get one from www.PBResource.com . Looks like a nice old Bingo!
Joe's Classic Video Games Thank you, i will check it. They didn't use it for a while and they really dont know its working or not... But its a EM, so not will be a big deal.😁 Thx
Hi. I am in need of help with my 1974 Gottlieb Magnotron pinball machine.
I have restored the machine to almost perfect working condition. I do have the original schematic.
When pressing the game button the game resets completely and the first ball is ready to shoot. When pressing for a second player, the second player coil is activated, the second player lights up on the backboard and then the machine goes through a complete reset causing the Control Bank to reset which resets the number of players back to one. If I manually trip the second player coil, the game works fine (same if I trip the second, third and fourth player relays without pressing the front door game button).
I have check the ZB relay which only has two separate make/break switches. Checking current on each, there is current flow if the second player relay is tripped or not.
Help, please?
Loved the explanations. I'm an electronics technician fixing aircraft test sets for a living. Ladder logic has always been a kind of mystery to me, you make it look simple, and I suppose it is once you get used to it. Thanks for the cool lesson. I have a D.Gottleib Big Shot at the house and it took me awhile to get it fixed but I've enjoyed it for years now. I see that everyone calls it a 1974, but mine says 1973 on the artwork, so is it a 1973 or a 1974, not that it really matters, I'm just curious? Thanks for the video. Best Wishes n Blessings. Keith Noneya
Thanks Keith, I appreciate it. Big Shot was the two player version of a 4 player game that came out in 1973 called Hot Shot. Hot Shot and Big Shot use virtually the same artwork, so the artwork on your game was designed in 1973 but wasn't released until January of 1974.
See you on the next video!
Hi Joe, how are things, I hope very well, would you let this schematic diagram to download, thanks!
Great video, thank you. I have an issue that I hope you can help me with.
My problem is that when I press the game start (credit) button, the score reels do not reset to all zeros. They will only advance one or two numbers. For example: I put them all on ones (1 - 1 - 1 - 1) then press start and they will advance one or two numbers (2 - 2 - 3 - 2).
They all score properly, no sticky or gummed up score wheels.
Now... I wonder if this is my problem - Just before this started happening my machine would totally shut down when the score hit 100. The problem was the 100 point chime coil was fried. I simply disconnected the coil and it works great now - except for the score reels not zeroing. I wonder if it needs the chime coil to complete some scoring reset circuit?
Any ideas? Thanks!
It depends on which machine it is, when the score reels reset they (on most machines) have a switch on the score reel that stays closed until it gets to 0, and then opens up killing power to it. These switches being closed keep the reset relay (or however it's wired) pulled in until they open, it sounds like yours are opening before they get to 0 making the reset relay drop out early. It's different on each machine though so you'd have to look at the schematics of your particular game to see what keeps the scores resetting and then find out why that is turning off early.
@@LyonsArcade It's a 1974 Bally Amigo. All the switches are operating properly (open on zero), it just won't reset. The chime solenoid is at the end of the circuit. Right not I have it disconnected. I went ahead and ordered another coil. (CG-29-1600). Hopefully that's the problem. Thanks!
Hey Joe, wondering if you can give me a hand diagnosing a problem with an Aladdin’s Castle em pin from 1976. I’m new and working on my first machine. Same back basic design as the one in your video. Problem is that when the “Aladdin’s alley’ rollovers are closed during gameplay, the solenoid that advances the stepper does not fire. However if you manually advance the stepper then close the ball drain, the solenoid will fire to return the stepper to zero ... everything else seems to be working, if you manually advance the stepper, the rollovers score the values properly, there is just no firing of the solenoid during gameplay.
I checked out the schematics, the unit steps up by using a switch on the score motor at 8C, a grey with red wire... that goes to a switch on the Aladdin's Alley relay and connects to a blue with white wire... which connects to a 9th position switch on the Aladdin's alley Unit and changes to a brown and white wire.
What you need to do is pop the playfield up with the game in play and hit the rollover switches, see if it makes the Aladdin's Alley relay pull in. If it does, check that switch on the Aladdin's alley relay that has a grey/red wire going to a blue/white wire. If that is clean and connecting like it should when the relay pulls in, look at the 9th position switch on the Aladdin's alley Unit.
It'll be a switch that stays closed until the stepper unit goes all the way around to the final position, where it opens it. If that switch is dirty or not closed, the solenoid will never fire. If the stepper unit hasn't ever been cleaned or rebuilt, this is probably the problem...
The reason the solenoid resets it is because it uses different wiring to make that happen.
@@LyonsArcade thanks man, chased it down to the ninth position switch. Got it going again, then it would cycle fired repeatedly on the first rollover every new ball, right up to special. Turned out the 8c wasn't breaking contact, gapped that one properly all works fine now!
There you go Corey, glad you got it working!
What are those numbers in the box like at time 26:02? 13-2 and 43-4, numbers in a box.
On these particular schematics, it's the color code of the wire. The first two numbers are the color and stripe, the last number is the id of how many are in the cabinet. So like a red and green wire, and this is the third red and green wire in the cabinet (they reused colors!)
Is there a good way to tell if I have the right schematic
I have a Williams 8ball it's a 1968 modle
It should say 8Ball right in the corner of the schematic. The correct one is on www.IPDB.org , check this out :
www.ipdb.org/files/764/Williams_1966_8_Ball_Schematic_Diagram_continuous.pdf
Yet... another "shot in the dark" question.
Let's say that I have an EM, that employs a gate (the 45°, swiveling bar that redirects the ball to an alternate lane).
Would it be possible to add another gate, in series with the other, at a different location?
If that is possible, would an additional gate have any effect on the rest of the circuitry? I realize that adding another gate
may produce a voltage drop/irregularity. But would it be enough to throw anything else out of whack?
I also realize that modifying a classic EM is sacrilegious to the purist. So please forgive me.
My first machine WILL get minor additions, but nothing "out of place" looking.... an extra gate, a bumper post past the flippers.
Thanks again for your time, Joe.
Yes you could wire that in just fine, it wouldn't mess up anything else. Basically you would just connect everything exactly like the gate is connected on it right now, but in parallel. So buy a gate with coil, mounting bracket, etc. and mount wherever you want it, then run a wire from each wire that is currently connected to the original gate, over to the new gate, and leave them both hooked up.
You might have an issue if there's a switch that you roll over, in front of the gate, that shuts the gate. The top gate wouldn't shut unless you hit the bottom switch which would shut both of them.
Ahhhh. That's exactly what I wanted to know.
There's probably gonna be a roll-over. But I wouldn't be grief-stricken if the add-on stayed open until the other was sprung.
However... I'll be looking to see how the roll-over was wired, and perhaps try to work out some reverse engineering. I'm sneaky like that.
Joe... thanks a ton for your time! Much appreciated.
A coffin for time, money and electricity :)
I played this game many years ago but it was a football game they both look the same
Yeah they made two games, exactly the same but with different art....
Hi Joe! I’m a new subscriber. I just got into fixing a 4 Player Gottlieb Jungle Pinball Machine. I do not know very much about the machines. Just got this one running today. But the scoring motor will not stop. I will press the start button and begin playing but the motor will not stop until completely turned off. Any ideas?
If you get the schematics there are switches on several different relays that can turn the motor on, basically one of those isn't ever opening so the motor always has power. You can open it up while it's running and see which relays are pulled in too, but on the schematic it will show you each switch that can give power to the motor and you can track it down that way.
Joe's Classic Video Games Thank you will try!!
Joe's Classic Video Games Got it fixed!! Thanks will stay tuned for more of your videos!!
Very cool Drew, glad you found it!
I see the liberal and conservative game adjustments on my schematic but I can't locate it in the machine. Do you know where it is and is there a reference on these schematics that helps you late the relays and wiring in the machine?
There's a manual that comes with each game too, all that stuff is identified in the manual... to find a specific relay too they originally were marked on the relay, but the sticker has often fallen off over the years. The conservative/liberal adjustments are usually in one of three spots, just inside the coin door on the bottom transformer panel (behind the coin box)... or directly above that on the bottom of the playfield... or in the backbox near the top in the middle.
I need help I'm trying to figure out how the score reel display works
What is yours doing? It kind of depends on the manufacturer, they're slightly different.
I have this very same pinball machine but it works completely differently. Most notable the soccer balls do not count up the way they should and I have never been able to figure out why. Let me know if your interested in seeing a short video on how mine works.
Yeah I could check it out, what do you mean it doesn't count up right?
@@LyonsArcade
Why you were manually setting things off to check the scoring and functions your soccer balls were adding up but on mine it takes a very long time for the soccer balls to add up. I notice when the ball gets to the end the score goes up very quickly. Everytime it goes up top through the gates it adds yards and every target will then add yards and if you put it through the spinner it adds yards for every spin. I'll see if I can figure out how to put a video up.
From watching this, the solid state games seem simpler to work on than these
They definitely are, but the EM machines are cheaper to work on that the solid states. So it's kind of a trade off!
Well, I can understand why they got rid of mechanical pinball machines :)
LOL it's all making sense now, huh?
Joe's Classic Video Games imagine Addams Family as an EM!
The lit lanes at the top give you 30 yards (3,000 pts) unlit gives you 500 and 3 soccer balls. Lit is better.
LOL, ok, my Gottlieb Dodge City just buzz and dont react at all to anything, no lights , no press left button to get it to attract. GO
Did you ever clean all the relays like you were going to do?
Haha you remember! Yeah i checked them all, and scrubbed them gently with a tool i bought, and fixed one in the backbox that had a bent switch, but i think i messed something up on the playfield, since it doesnt react to start-ups anymore, so i gotta go through that , with the schematics i got for it (NOS too, even), but at the moment im fixing my JL. :)
Slam Switch, the one with a weight on it on the underside of the playfield? the one on the door is closed. and it got 5 balls in it, that was already in when i got it.
These diagrams are based on ladder logic any electrician can explain them, but if you want to learn the basics find old machine control diagrams and books on early plc programming and computer programming as thgey all work off Boolean logic.
Sounds like a drum switch issue.
When my pinball goes into the hole it starts clicking and the ball doesn’t recycle. What would that be called?
When the ball ends depending on the game, it tries to count bonuses, and move the ball count unit to start the next ball... so something in that area isn't clean or isn't moving right, and since it never moves the score motor just keeps turning which is the clicking you're hearing.
ITS DC VOLTAGE IN THE MACINE NOT AC TRANSFORMER IS POWERED BY AC BUT CHANGES VOLTS TO DC
