Score Motor Problems On A 1977 Sonic Prospector Pinball Machine - Schematic Reading And Repair 

Thank you for watcihng Mark! Happy Thanksgiving, even though you're not American I'll bet you've got some things you're thankful for :)

That's cool Dan, that's why we make videos like this with the hopes that somebody will be able to use it to fix a game somewhere I can't reach :) Thanks for watching, see you on the next video!

Notice how the end of the ball is actually controlled by the bonus units, Grand Prix works the same with with that 0 position switch that opens and closes, you'll see when you get into it. Same exact bonus unit too, there's just two identical ones on Grand Prix and each ball it changes back and forth. You've got your work cut out for you, Grand Prix was the most complicated one I've worked on!

Hmmm, its on player 1 ball 1 pressing start button doesn’t move to two player game? Playfield is removed. Can’t find start button on schematic. Yikes.

Thank you for bringing them up Big Bob, if you need any help on those EM's let us know. If you get in any more machines for sale we're always buyin' ! Thanks for watching!

I just don't film the next part until i've figured it out, I'm cheating :)

@@LyonsArcade you still do it and to be fair there must be a lot of head scratching we don't want to see, and the walk through is just fine !....cheers.

Yes I've been trying to explain to people that they're almost identical to how modern PCB's work it's just all condensed into one chip. It's all 0's and 1's!

Thank you T.C. Bowling!

Thank you for watcing Rene as always!

Thank you v8nagrom! See you on the next one, eat a lot!

Thank you RC!

Thank you Petri547, happy thanksgiving!

When the Pilgrims came over they started a communist villiage and half the free loaders wouldn't work so they about starved to death. The Natives taught them how to hunt and fish, etc. but half of the Pilgrims wouldn't work, because that's what Communism is all about. They eventually divided the property up into a more democratic system where you work your own land and prospered, they had made peace with the Natives and invited them over to have a big party to thank God for bringing them all prosperity, food and a new land. Later down the line we killed all the Natives and took their land. Here's a story about it from Rush - officialrushlimbaugh.com/the-true-story-of-thanksgiving/ And here's a story about Osceola, years later, who was imprisoned and was involved with the loss of Florida, the whole country was stolen in big swatches. Most countries were founded this way.... - nativeheritageproject.com/2014/05/10/seminole-chief-osceola-billy-powell/

@@LyonsArcade I'm quite familiar with communism..the PM here is one

@@LyonsArcade further more..each and every NZ business is crying out for staff..shit ton of vacancies and nobody applying..job seekers market you'd think but thanks to farkin socialism..nobody is applying for any of those positions

@@LyonsArcade What would the Duke think of his USA if he was still around today..I think we can all guess that

Thank you Dano!

Yes it's in very nice shape, they did a good job making it durable! Thank you for watching Kate!

I put a sink order to Donnie on your behalf Kate..you're welcome:)

Who's Donnie? 😏

@@naytch2003 I have no idea. Perhaps a few mentions but never an appearance.

@@gorillaau sounds like an interesting character 😆

I think ours is stuck up now that I look at it! Thanks for watching Paul!

Probably. There's usually half a dozen or so on each machine that aren't touching anymore.

I thought it was designed like that but there's a gate up there that's stuck open!

By 'covered' do you mean, like you can't see through it, or you see spots all over the place? I'd probably save it personally but i'm much more tolerant of that stuff than a lot of people, might not be a good idea.

By "Index" they mean that's where it starts, so for instance if you read the index of a book, it tells you what page everything else is on... you start looking there. So that cam is called the Index, because when it gets to that dip you're talking about in the wheel, that is the starting point... so it turns around until that point, and stops. It does this so that it always starts in the same place, that's why they call it the Index. Thank you for watching Wayne, happy Thanksgiving!

@@LyonsArcade Thanks, I didn't know that the Index CAM is the starting point that all other relays/coils are "referenced" off of the index CAM and Index relays/coils

On these it's never a problem because of the way the cams are bolted on... on the Chicago Coin ones the hub holds everything and the upper cams are just screwed to the bottom cam, you never have a problem with anything but the hub. This cam system was used by Williams and Bally and doesn't really have any problems even though they're nylon. Yes on the Chicago Coin ones they changed a couple times but were used for many machines before they changed slightly, probably because the games got more complex as time went on and they needed a slightly different cam. I think this score motor has an Index, a "Long Dwell", a Impulse, another Impulse, and 5 position cams, so 9? Very complex game!

Yes it plays very fairly! Happy Thanksgiving OCSRC!

ours is stuck up (like some of the viewers hahahaha)

Flappers in the day were known for outrageous things 😁

Come on now Mike, that.... you can..... come on now, you can't tell if .... you can't tell if it's Broke come on now Joe ain't here right now come on people... you can't tell if it's broke, come on now

@@LyonsArcade this machine is great! Thanks for the uploads, Ron!

Happy Thanksgiving Lil Everette!

Absolutely! I see you've worked on one before :)

Mine too!

You're quick today :)
