ANYTHING! you buy on Amazon after clicking that link doesn't raise your prices but gives us a referral tip, thank you!
Where did you find the schematic to it I have one of these machines but I cannot find the schematic so if you could send me a link to it that would be great or tell me where I can buy one
sorry to be so off topic but does someone know a tool to get back into an instagram account?
I was dumb lost the account password. I appreciate any help you can offer me.
@Wyatt Kairo Instablaster =)
@Vance Jeremy I really appreciate your reply. I got to the site through google and im trying it out now.
Looks like it's gonna take a while so I will reply here later when my account password hopefully is recovered.
@Vance Jeremy WTF IT REALLY WORKED! Literally hacked my IG login within ~ 45 mins of using the site.
I had to pay 15$ but for sure worth it :O
Thanks so much you saved my ass !
Man. Every time you post a new video I crack open a beer and just chill out. Great level of wit, knowledge and skill.
Thanks.... you Hak you. LOL
I do the same. A lot of tierd days at work.Staying up one more hour to see the next video.
On my way back to work on my daughter's Grand Prix. I watched the entire video again to get ready for next week. Thanks again for the great videos, especially the schematic reading which is a whole thing all by itself. Quite different from electronic schematics.
Just took a trip down memory lane. Enjoyed this as a child. Thanks
Very cool, thank you for watching!
Just purchased a Grand Prix and your series of videos had been super helpful. Keep up the good work! 👍🏼
Thank you DJ Elvis!
This was certainly the most complex, challenging and interesting pinball machine repair video series I've seen thus far. I like the look of the game too. Great job Ron!!!!!!!!
Thanks for the great videos on the Grand Prix! Super helpful!
Glad you enjoyed them Bill, thanks for watching!
What a fantastic video. Thank you for this. Very informative and easy to understand. I just bought my first EM which just so happens to be Grand Prix, so this is very invaluable.
Well great, glad you enjoyed it! Enjoy your game, it's very fun :)
You do a great job walking through the schematics. And as you mention in the video, if you look at your problems logically while working through the schematic it makes a lot of sense and becomes easier to follow/understand.
Thank you so much for the detailed look at schematics. I would love to see more EM pinball schematic detail, especially if you come across an old stern..
Great schematic troubleshooting info! Makes me want to go and attack my troublesome Jack-in-the-Box pinball game again!
Go for it, Dan. You can get her purring again :) That's a great game.
Wanted to add - If I come across one of these - I would buy it and fix it.. just because its the most complicated machine and you made it look fun :)
Thanks Bob, yes they're very fun to fix and fun to play too :)
love this project!! but dangit..i keep falling asleep haf way through!!!! lol..LOVE the video! classic commentary ..and knowledge ...and you never get discouraged! lol
I just keep going if I run into issues I just write it down, eventually I'll figure it out :)
I've just got my first table since the 80s, it's a Williams Dealer's Choice and it seems to have even more in it that this one. Thanks for all the schematic interpretation, it is helping me get used to reading them and I need to because this"fully working" table has about 20 minor faults and every major component has at least one fault. I wish I was in the USA where there seem to be some great repair people :)
Awesome video, I have this same machine & you covered some issues I have with mine. Now to dig in & see if I can get it running right again.
You can get her going Troy, just takes a little time!
Well done!
Thanks Bob!
Stainless TIG rod from a welding shop will probably make great rail wire. Lots of sizes.
Thank you Kay Bax
Thanks on all that info, just bought one.
Very cool, hope you like it!
I would swear that "W" logo for Williams is an exact copy of the Motorola logo, but upside down :)
Or Vice Versa, we've been trying to figure out if it's the Chicken or the Egg :)
@@LyonsArcade A great question indeed! From some quick research, Motorolla had officially changed to their famous M logo from 1955 to current, which one would assume they had it first... however, looking into WMS industries, they started making pinball games from 1943... and all the logos ive seen on the internet, either had the word Williams with the W at the end or just the W... damn it, Ron/Joe, I need to know, this is the stuff that will keep me up at night! :)
Great work man👍work great now !
Thanks Danijel, yup it was fun!
This is a really helpful video. I also rediscovered the book "Introduction to Coin Operated Games" by Williams, I downloaded a PDF quite a while back. It has a very good section explaining schematics and their symbols on pages 48 to 55. In particular, I find the make/break switch symbol confusing on the schematics and it is explained in the book. EM schematics are quite challenging and unfortunately experience with standard electronics schematics is not very helpful. For instance, I am still getting used to the fact that the EM symbol for a switch is the electronics symbol for a capacitor.
I actually have one of these. I need to get off my a-- and fix it ! I used to work on them for a route operator in the mid '80's.
You can do it Bill, make it fun again :)
good video, I learned a lot.
Thanks Robert... see you on the next video!
Man that an electronically complicated pinball machine. Keep up the good repairs.
Thanks Doug, will do!
Awesome video as always :)
How many hours did you spend on trying to figure out why the 1, 2, 3, 4 can play lights weren't working? Haha
Heading for the play video now. Fantastic to see these being brought back to life as always :)
Thanks Marty! About an hour, LOL
I love your channel! Just picked up a Grand Prix machine today. It's in great shape, but the ball eject isn't working. Any suggestions for getting it to work again?
I know that ! said many four letter words when working on these units!!!
It's a very complex game!
thanks for responding back to me, you do a "GREAT" job of explaining what you are doing when you are doing repairs. I noticed that you have the ability to read "ladder" wiring diagrams, that is so important to be able to do in "troubleshooting "problems. after all the wiring diagram is the electrical "ROAD MAP"!!!. yup!! try to repair /troubleshoot a problem without the "wiring diagram"???. have a great day!!!. ( I did subscribe !!!)
Thanks for another informative and enjoyable video!
I notice the top kickout is ejecting the ball off to the side instead of straight out, right where that playfield wear is, not surprisingly. Is the kickout assembly maybe a bit off kilter? Should it be adjusted so the same spot doesn't continue to get disproportionate wear? Or would that be tampering with the intended design of the gameplay?
It's actually designed like that, so that the ball heads to the pop bumper instead of straight down the middle.... if you look at pictures of other ones you'll see they all have that same wear there on the right. You could adjust it but then you'd end up with another wear spot eventually :) If you keep the playfield waxed it shouldn't wear like that, it's usually a sign that the machine was played for a long time without being rewaxed. Basically the ball wears through the wax, then starts in on the paint!
I'm finally to the point where I need to get new rubber rings for my grand prix machine curious what you went with ?? I'm new to rebuilding machines and I'm finding there are a couple different choices to be made. Curious to know what you went with and why? I'm a fan of keeping the machine original. 🙂
I would just order regular white rubber rings for it, usually there is a kit you can buy with all the rings in it, I usually get all my stuff from Marco Specialties... I don't order ring kits, I just order multiple quantities of all the rings and have them in stock, so when we do a machine we just have stock of all the rings they need.
Rolla rolla ding ding !
Great video! I just purchased a Williams Grand Prix and it's set to free play. I'm thinking about returning it to coin operation. It has all the guts on the coin door. How would this machine have been turned into free play so I can reverse it?
Usually there is a switch on the play unit or credit unit (in the backbox with the credit number on it, the big wheel)... .there's a switch that opens when it gets to 0... if that switch is bent so it never opens, it will be on freeplay. So you have to get that big stepper unit working where when it gets to 0 the switch opens, and when it gets to 1 the switch closes. Sometimes they did it by cutting the wires to the coils that move the stepper unit.
What kind of wax do you use on the play field?
A car wax or floor wax?
Or does it have to be a special kind of wax?
I use a Carnuba car wax. The secret is if you do an old playfield, if you use a white wax you'll see all the cracks in the playfield... but if you use Carnuba it's yellow and any wax on the playfield in cracks will be invisible.
Any idea how best to adjust the height of the little plastic covers over the bonus lights on the play field? They cause the ball to shift around quite a bit on my machine..

I made the flipper gap larger on mine by putting a shorter vertical wireform in the inlane so it's very evil if you try to trap the ball on the flipper.
LOL that's awesome. I was playing a game not too long ago setup like that....
Thanks for great video. Question - when you re-cleaned the contacts on the bonus stepper to make them super shiny, how did you clean them? Thanks!
Fine sandpaper, just don't go crazy with it. You don't want to eat down the points, just get them shiny...
thanking ye! Something like 220 grit do it?
You can also use the green scotch brute scouring pads. They are also great for cleaning the Jones plugs!
Sorry, scotch brute......fat fingers error.
Brite! Scotch brite!
8:30 you know what, i don't have a ball in it. minor oversight!
Whoops!
How do you clean the art work without damaging it? I have same tiger handhelds that are just terrible. I needs helps
The wood we clean with magic erasers, the plastic just with windex. Novus works great too.
@@LyonsArcade thanks! one more question, what do you guys use to disinfect really dirty machines? is it novus? where can I find novus.
What do you use to clean the plastics and inside back glass that doesn't destroys anything ??
We literally clean them with Windex.
@@LyonsArcade and it doesn't any of the graphic ?? 👍
If they're in good shape nope it just cleans it up. If it's worn we just take it easy to make sure it doesn't come off.
Jokes aside Ron.. looking forward to the next time you and Donnie have a Livestream..missed the last one due to having COVID..heard this morning some nutter invaded my son's high school..cops managed to subdue the twit and arrest him
What did you clean it with?
We clean all the dirt off with 409 and magic eraser then wax.
If it's blood, some fool probably got his finger caught in the one-way switchover relay while the juice was on...
