Ronnie is so good at this! Even his pinball sound effects are on point! :) Thanks!

[@LyonsArcade]

Thanks Miguel, we appreciate you watching us!

[@corneleousworthington4566]

The painted red really tunes up the look of the game overall! It's a GREAT old Bally, but the all-green always made it look a little boring. Now it looks awesome! As always, thanks for the content!

[@LyonsArcade]

Yeah it's the rare instance where it kind of made it look a little better, ha!

[@tcb8295]

Ron, as always, another great video. Thanks for taking us along.

[@LyonsArcade]

Thanks TCB!

[@JendaLinda]

I'm giving the thumbs up already while the intro ad is playing.

[@LyonsArcade]

You ROCK JendaLinda

[@pauz2175]

Great stuff man. I’ve brought a few EMs back from the dead but I learn something new every time.

[@LyonsArcade]

Very cool man, thanks for watching!

War gut, Reset-Schaltung mit Moter-Nockenschaltwerk hatte gesehen. automatisch Null-stellung. 👍

[@andymouse]

The T Rex has got speared right in the willy !...cheers.

[@LyonsArcade]

Yup, what a way to go!

[@lepterfirefall]

That looks SOOOO complicated. So many parts. Not at all interested in pinball games but it's still fascinating to watch.

[@LyonsArcade]

It looks really complex but when you're working on them there's really just a few 'systems' laid on top of each other, so for instance a lot of that is for lightbulbs. Then other wires are running to coils, and other wires are running to switches. So depending on what you're working on, you can ignore a lot of the wires and just see the few wires that go to what you're interested in fixing.

[@lepterfirefall]

@@LyonsArcade I see. It's good there are still experts out there who know how to fix these classic machines. 👍

[@GOTTshua]

Seeing the insides... gives me the vision of designing & building a one-of-a-kind creation. That would be a labour of love... and a whole lotta learning. A beautiful dream. Perhaps Jesus has a lovely workshop planned in the place He has prepared for me.

[@mcostafernando]

Nice shot of the score motor running at 40:58 !

[@LyonsArcade]

Yup, pretty cool watching it do it's thing!

[@rcfreeman]

Excellent video Ron. Learning a lot from you. Hit the thumbs up in the first min,....come on man

[@LyonsArcade]

Thanks RC We appreciate it!

[@4ngu54110tt]

I like the old EM restorations. You can just imagine the smells of the used bubblegum and spilled soda from an arcade...or if its been in a bar with the nicotine and stale beer patina. Mmmmm mmm.

[@pezjohnson]

Nice work on cleaning all that. Interesting about the score reset. My Dealers Choice fires the 3-4 player reset constantly when the score motor turns. Not a big deal for a 1 or 2 player game, but if points are on 3 or 4, they start advancing until they get to zero. I'll figure it out one day.

[@LyonsArcade]

That is a strange one, the 1and2 and 3-4 are fed by the same circuits so even if a switch was stuck it shouldn't do that, it would make the 1-2 one do it too. You may have a wire touching somewhere it should be... the only thing that separates those two relays is they use two different impulse switches to fire off the score motor, but if the impulse switch was stuck it wouldn't fire over and over again and it wouldn't fire anyways unless the reset relay was on. If the reset relay switch was the problem both the 1-2 and 3-4 would do it.

[@flatfingertuning727]

@@LyonsArcade I wonder what the pros and cons would be of designing a machine so that rather than running a reset sequence until the score reels are all zero, it would start a reset sequence before deducting a credit, run the reset sequence for a fixed length of time, and then either deduct a credit and start the game (if the reels were all zero) or else proceed directly to "game over" mode. If the machine fails to start, a player could push the button again to repeat the sequence without losing a credit unless/until that succeeds, but the machine wouldn't simply run forever.

[@EngineeringVignettes]

*ding* ding* ding* I'm on fire today! ... No that's just the 10-point relay.

[@LyonsArcade]

hahaha yeah it must have gotten a little excited at some point!

[@naytch2003]

Cmon baby light ma fire!!

[@Jeroen_a]

There is a saying in dutch that goes a bit like this " He has heard the bell ringing but he does not know where the clapper hangs" (he does not know what he is talking about) ..... i think we found the clapper :)

[@LyonsArcade]

That's a great saying, never heard that one before!

[@demofilm]

We need to get those translations to a point that they make sense for English language. For example you can smell the burning relay one hour in the wind 😅😂😂

[@demofilm]

@@LyonsArcade these dutch sayings let you now how bad, good, strange something is. We use them all the time. For example the knife cuts on both sides... it means for example when i buy a new multimeter you can buy my old one. I get some money back and a new meter, and you get a nice meter for less money. So it is good for both sides.

[@Jeroen_a]

Even though she's wearing a golden ring, she's still an ugly thing? :-D Hey, that even rhymes in English :D

[@Jeroen_a]

Makes sense too :D

[@waynegram8907]

JOE"S CLASSIC, The Jones Plugs are different sizes for Williams, Bally, Stern, Gottlieb? because you mentioned that the Jones Plugs are different sizes. I'm not sure why that one jones plug is Longer than the rest maybe that is considered the KEY so you can't plug it in backwards?

[@LyonsArcade]

They have a little bar at the end so you can't plug them in backwards... the jones plugs seem to be the same size from company to company but they're all made slightly differently.

[@jk9554]

9:25 technically, there can be cases when a coils resistance can go down gradually - if there are a few findings in there where the coating has burned off, they short out and resistance goes down, along with the number of "effective" windings in the coil. With lower resistance, there's more Amps pushing through, so it probably has a slightly higher chance of failure, should it get stuck on again.

[@PlumGurly]

The bore brush thing reminds me of a joke. A kid was chewing gum in class and the teacher asked him, "What 3-letter word that starts with G is not allowed in class?" He said, "God." Isn't that the truth too? And the other g-word (fuegas de armas in Spanish) is something else he could have said.

[@derofromdown-under2832]

Why don't you use alligator clips in the end of your multi-meter probes to take your ohms checks?

[@LyonsArcade]

Because i'm not as smart as you Dero, remember we went over this yesterday, you're smarter and have it all figured out buddy, whatever you say is the correct way

[@EsotericArctos]

Sometimes they deliberately make a post longer than the others to ensure that connection makes contact first before any others. It may also be just a mistake :)

[@LyonsArcade]

That makes sense but why are you unplugging it when it's turned on, hmmmmm????? Thanks for watching Brendan!

[@stevengentry9752]

Hey Ronnie, love all your pinball videos. Really appreciate you sharing all your knowledge on this stuff. I have a Four Million BC that I have pretty much got working except one problem I just can't figure out, which is killing me because I am sure it is something simple. Maybe you can help me out. Once the 1000 point score reel hits 9 and the 9 position switch is closed, it draws in the 10000 score reel coil and keeps it energized (pulled in) until another thousand points is reached then it releases it. Didnt realized this was happening until i burned up the coil. This happens every time the 9th position switches are closed and happens on all four players. What do you recommend me looking at? I cant find the problem an I am really getting frustrated at this point .

[@LyonsArcade]

Ahhhh, that's an interesting one. So the way that thing works is, when it gets to 9, that switch on the 1000's reel stays closed, so that's correct. The next time the 1000 pt. relay pulses, it should pull in that 10,000 pt reel.... since yours does it immediately, and on all 4 players, it can only be 1 switch.... there is a switch on the 1000pt relay that ONLY pulses that 10,000pt reel, but if that switch is stuck closed, you would only get the issue you're seeing, so it's pretty much got to be that switch. Look on the 1000 pt relay, there is a switch with a yellow wire on one side, and a white wire on the other side. That switch must be stuck closed causing your problem....

[@stevengentry9752]

Thank you Ron. I was 99% sure the problem was in that 1000 relay. I must have cleaned and examined it 7 or 8 times but everything looked like it was operating correctly so figured the problem must have been somewhere else. But since you gave me your expert advice, I really dug into that relay. There was indeed a switch closed at all times regardless of the status of the relay. Looked like it was supposed to be that way (not part of any make or break switch). Slid a peice of paper in between the switch and problem disappeared. Bent that switch so it doesn't make contact and everything work great. Not really sure why that particular switch is there, nor do I care at this point. Everything is working!! 🥲. Thanks again for your advice on were that problem was, would not of found it if it wasn't for you insuring me the problem was there. Also appreciate all the videos. Thanks for taking all the time to film all of them.

[@markwhitfield5412]

graphite dust is an excellent lube, if lube is the right word, it makes things slippy without drag, as oil and grease do, maybe not a good idea on electrical contacts.

[@wartoc3708]

Silicon grease for nylon (any plastic) which is also safe on rubber (plumbers use it for rubber seals). Avoid lubricants that are petroleum based as they will destroy plastics.

#videorobot was here

[@LyonsArcade]

Welcome Videorobot

[@Jeroen_a]

Does the switch on the credit unit also disable the coin door mech? so when you have 25 credits and it hits that limit switch it disables the coil of the coin mech? That would solve the coil that needs to be on all the time (if present).... but that might introduce other issues i guess

[@LyonsArcade]

Yes you are correct. That switch when it opens (because there's too many credits) it disables the coin door. The way the coin door coil works is, if the game is turned off, or that coil is turned off by that switch, the coil has a little wire on it that pushes into a slot on the coin mech, when the quarter falls through it hits that little wire and rolls out the front. You can disable that coil by just clipping the wire to it, and then bending the metal piece so it never blocks the coin mech...

[@Jeroen_a]

I was just thinking it would be nice to let the machine know it has enough credits so it disables the coin mech and without snipping wires... you know... to keep it even more original. I don't know it that would introduce other things like the knocker not working (probably because it can't add a credit) or something :)

[@Jeroen_a]

Who ate the playfield?

[@LyonsArcade]

We lost it, we'll find it around here somewhere!

[@wolfweb]

Does anyone know what Ron looks like? Wouldn't mind knowing! I imagine he looks like Colonel Sanders, in a spotless white suit with a perfectly trimmed white goaty.

[@LyonsArcade]

I look like a cross between Leonardo Dicaprio Brad Pitt and Elvis but I'm slightly more normal than them.

[@wolfweb]

@@LyonsArcade That makes sense! Thanks for the videos Ron. I bought my first pinball 2 weeks ago, a Target Alpha and you helped me fix the bonus unit which I had to pull apart but could do it given your description of how it works. Also the lights in the lightbox and next is to fix the match which I think is something to do with the FS relay. Your EM repair videos are keeping the dream alive brother, they are what gave me the confidence to open the playfield.

[@thiesenf]

Shouldn't the Jones plug be called "John Holmes plug"??? *CRICKETS*

[@LyonsArcade]

Maybe that one...

[@thiesenf]

@@LyonsArcade Yep... that one... :-)

aligator clips for your multimeter leads

[@jokeeffe007]

I want to add to your Fluke statement. The cheap multimeters can also have problems with higher voltages even if they are rated for them. Fluke will keep you safe all the way to their rated voltages. You never know when you are going to see a high voltage when working with electricity and old equipment. Thanks for all the continued great content!

[@LyonsArcade]

Thanks Jim, I usually don't mind cheap tools but in this case it's costly to use a cheap multimeter sometimes! Thanks for watching!
