Brought home a 1969 Bally Joust from the York show...a known project. Game will not boot/cycle or even light up. Plug it in it does nothing. Transformer looks satisfactory. Jones plugs look good with no broken connections. Do need a schematic if anybody can assist (it didn't come with one), and I don't see one on IPDB.

Anybody have an idea where to start to get some juice to this thing? Would like to get the game up and running, and perhaps a restoration in this little guy's future. Any help is always appreciated.

Transformer...

Found a few hacks (not that would prevent it from at least powering up as far as I know). Geez...looks like they used wire from a lamp or old extension cord.

Another hack? A leaf switch in the ball gate? Looks like they just ran some more extension cord behind the playfield.

Thanks for chiming in. I've never tested a transformer. Looking up something to guide me now.

Yep.

Thanks Chas, I’ll check out PBR. The fuse in front of the transformer should be an 8A FA or SB?

So if I push on the metal tab on the other side of the coil of the anti-cheat relay, the lights do go on. But I have to hold it down.

In your pictures, you have the Jones plug receiver grounded correct? And you have the black COM lead from the meter on the proximal lug of the coin bounce? And I should get a reading of 1 when testing the two pins on the Jones plug that you are?

Does your game have a toggle switch? This one doesn’t and it looks like I’m pushing directly on that coin bounce switch with the button under the cabinet. And this one is a pushbutton like a Gottlieb. It looks different than the inside of my Vampire (3rd pic below), which has a toggle.

I’m getting continuity also on the Jones as you had it.

So you were plugging the machine in every time you wanted to play it?

No, bought from Don. Deal done before York, and he brought the game for me. Nice to meet you at the show.

All the slam switches should be closed, correct?

Cool. I was going to look at it again tonight. I’ll get back to the thread later. Thanks.

So I count 6 slams. All of these should be closed?

Back to it...so bottom PF slam open and all other 5 closed? Checking and adjusting now. I think others were open.

I’m pretty sure it was good, but I’ll check that out too.

Cleaning up nice even after the first light round...this thing was filthy. Didn’t even strip the playfield yet. My little helper was pitching in too. A little before and after...

I noticed that. You or your buddy at Pinball Parts carry new ones? I want to replace them anyway.

So that 10A fuse was bad. Is that supposed to be FA? I replaced it, and a few solenoids are firing when I engage the stopper on each coil manually on the transformer board, but a lot of them still aren’t, including the flippers.

And the game GI still isn’t lighting up unless I manually engage the anti-cheat coil.

And...if anybody could send me some hi-res pics of their cabinet I would really appreciate it. This one was painted over, and I want to restencil it.

I do, but they are nearly black. I can see the values. Just replaced all fuses through the whole game.

Replacing that now. The fuse clip snapped off, so I had to replace the holder.

I saw those pics. Looks like the same ones from IPDB. I was trying to get a straight on shot so I could gauge the dimensions of the artwork to redraft for the stencil. I guess I might have to just use those. The backbox will be tricky from those crappy photos. It’s a little more intricate with the shield.

And there is life!! One of the score reels is buzzing, so a switch must be stuck on the playfield somewhere. Thanks for all the help so far guys. Much appreciated.

Unfortunately I do not. Any shot of you hooking me up with a PDF version of it?

Also, when I plug the game in it automatically turns on. At least the G.I. does and it begins normally when I hit the start button. My left flipper by itself does nothing. Not sure if it is bypassed somehow.

On my Vampire, you flip the toggle, then hit both flipper buttons and the G.I. lights. Then you can start a game.
