A lot of people seem to hate EM machines, but I find them very fascinating to watch the mechanics of them compared to later machines. The engineers that designed EM pinball machines, EM gun games, EM baseball games, Juke boxes, etc were geniuses.
That issue with the lighting makes more sense now. It could have been a bad earth and it was earthing through a different line, causing the light the light with the least resistance to light. Good find.
One of the comments yesterday was a gentleman who said he had it do the exact same thing on another machine, and it was a bad connection on the jones plug too so yeah that could be it! I can't figure out how it was grounded though but i'm sure it makes sense! Thanks for watching Brendan...
This is the best analogy I have seen explaining and showing how the relays and score reels work. Your video absolutely helped me with my Stardust scoring problem. In my case, the EOS switch on one of my reels was broken off. Watching your video I was able to see the fallout of not having the switch there. I knew that a broken contact on the switch was a problem, I just didn't understand how it all tied in. Thank you so much for the great video. I know these old EC machines are tricky and you make it look easy, but I know it's not. Thanks again!!
Thank you Patrick, i'm glad it helped, I try to make it where people can understand how simple it actually is, it just looks hard but once you think about it a little bit they make a lot of sense :)
Great explanation of mechanical logic computing.... IF not equal to zero then keep subtracting until = 0 then go on to the next boot step. Awesome! Floating grounds are the worst to troubleshoot. I had a 1979 Fiat Spider and the break lights would turn on the turn signals. Found one of the tail light modules had a rusted ground lug. Cleaned it up and tightened the nut and she was great after that.
A Pinballmachine is extremely complex. They almost overrule the complexity of a Car. My tip is! If you have a problem with your Car! Go and find a schematic from a pinballmachine and you will solve the problem easaly! Merry christmas.
I picked up a Jubilee a few months ago. My wires were intact ;). Thankful for this series as im fighting The Rona and stuck in bed. I will watch...kick this rona, and start clean, clean, cleaning jones plugs, switches, and steppers.
Yikes! ALL those low voltage, open contacts... It doesn't take much corrosion or a speck of dust to prevent it from conducting. It seems the guys engineering these machines were using decades-old technology, even in 1973. Still impressive they got it all to work reliably.
It kept those pinball repair contracts going! Cool seeing you here - your dairy electrical short circuit disaster video is one of my all-time favorites.
The score reel shifting (with the lit 1 and then the shift of the 3 reels to the left and the fake 0) it's nice to see evolve over time :-) you change a tiny thing and you can get a higher high score :) ofc the 7 segment displays changed that again and the dot matrix etc.. :)
When Jersey Jack Pinball designed the Wizard Of Oz pinball machine 10 years ago or whenever it was, they dropped all the zeros so the scores went back down more similar to how they used to be, lol
20:22 look at how the right wire is connected there... almost looks like only its isolation has been soldered in (probably it's two strands of wires one of which is actually soldered in).
Yes, look on the score reel that won't reset, there are three sets of switches on the top of it. One of those sets should stay closed when it's not at zero, and open when it gets to zero. If that switch is open, when the machine tries to reset it the power doesn't get through to the coil (in reset). Basically it keeps sending voltage through that switch until the switch opens. If the switch is already open, it'll stay on whatever number it's on and never reset. You could possibly have a open switch on the reset relay too, there is one switch for each reel....
Some years ago, I was confused at how score-based replays could work reliably until I realized that score reels advance when the solenoid is released, and the replay score contacts close when the score is 1,000 below the replay score. A replay is then scored if the score reel is powered while that contact is closed, which will be the event which advances the score.
JOE"S CLASSIC, I'm confused when all the score reels are at ZERO how does the Reset circuit coil knows that all the score reels are at ZERO? because all the score reels switches are OPEN?
They have wired the reset circuit up so that many different circuits can energize it, and so when each circuit gets to where it's supposed to be (reset), that circuit is no longer energizing the reset coil. So when all those switches 'open', none of them are still connecting power to the reset coil, which means it turns off.
I dont think ALL of them is open! I think that the Reset circuit goes thrue more than the Reset relay. There are all those swithes on the scoremotor that do there things to it! Keep watching Joe´s older videos and he explain. Merry christmas :)
@@LyonsArcade I didn't know that each pinball games Reset circuit and Reset coil was wired differently per pinball game? Is the reset circuit and the reset coil the same thing or both are different?
Wouldn't the reset operation just have to send 9 pulses to the score wheels? That way it could be sure the scorewheels would all be on 0 where the power to the reset unit, sending pulses, would be in the off position through the leaf switches at the zero position? No need for the reset unit to know at which number the scorewheels are.
Then you'd have to make the reset operation know what 9 pulses were, though. How would it send 9 and only 9? The way they have it now, it just sends however many it needs to, until the switch opens up to turn it off.
@@LyonsArcade They could have done it like they always seem to do, a rotating disk with a pin that opens a switch as soon as it turned 9 clicks. and te reset operations knows when a score wheel has reached zero, cause switches open. Just an idea of how they could have done it too. Happy new year! :D

Yeah I really like the EM's!
Great work! From a mess to like from factory. That mess on the wiring would have driven me NUTS!

The first thought I had was a bad ground, lighting in vehicles big and small do the same thing.

Floating grounds are the worse in Gottlieb system 1 and system 80 solid state, as they can destroy chips, some of which are unobtanium.
I watched the reset in slow motion, it was cool to watch. It advances each reel until it passes 9 to zero and stops.

Thanks for the video and explanations, Ron.
Thanks for watching !
Upvoting before watching. Because.
Thanks Aaron you're the man :)
Same here!
Ron, just picked up a Night Rider em!!! Gonna need love...but, have large schematics and some billy know how (and your vids)...here we go!!!!
Very cool, I've got one here in the shop I'm going to be working on soon myself!

Sherlock Holmes would be proud! Think I would be using this for target practice by now! waiting to see the back glass and field painted. Nice Work!

You're such a tease Ron.
Coming Soon :)

The wire is soldered in , the cloth covering is sticking off over to the left :)
What a tease!
coming Soon :)
Thanks man! Love getting a look into your world and appreciate your skill and craftsmanship.
Happiest of New Year's Ron, Don and Joe!
👍👍👍
Ron, is there a reason why you don't put any dielectric grease on the Jones plugs?
They didn't have them originally so I don't add any, that's the only reason.
Happy holidays to you and your family and keep the good working going m8...
Thank you Taylor, we appreciate you hanging out with us! Happy Holidays!
Thanks for the video!
Thanks for watching, mysterious x!
I have a Williams 1969 seven up pinball machine that can’t reset the 1000 score wheel. Do you know what resets that score wheel?
Yes, look on the score reel that won't reset, there are three sets of switches on the top of it. One of those sets should stay closed when it's not at zero, and open when it gets to zero. If that switch is open, when the machine tries to reset it the power doesn't get through to the coil (in reset). Basically it keeps sending voltage through that switch until the switch opens. If the switch is already open, it'll stay on whatever number it's on and never reset. You could possibly have a open switch on the reset relay too, there is one switch for each reel....
cool.

Oh no, the camera gets so heavy. lol. Another good series so far.

I wonder why when resetting to zero they all pause for a brief moment around 5.
It has something to do with the score motors rotation keep in mind the game isn’t working yet
on this episode of learning with joe...
Thanks for watching Tracy we appreciate it!
How do they work? Answer: Fairies
They turn them reallllly quick sometimes!
Denzel Crocker knew it all along.
Nope- magic smoke. If Anything goes wrong, it escapes VIOLENTLY!
