Jennings em wiring

[The Swede]

Does anyone have a wiring diagram for this or the mills M? I think that machine is the same. I bought it unseen in boxes and I can't figure out the transformer and hopper wiring, feels like I'm missing a pice of harness there in between. Maybe someone has a galaxy with hopper and could help me with pictures?

The Mills M didn't have a hopper but did have an electric handle release solenoid I believe, like my Mills "Open Front."
I had the next model of the Mills that did have the hopper, but I don't think it's the same as the Jennings! I'll look around and see what I can find.

I found this right here on NLG but not sure if the diagram is for yours. I'll post the diagram and the link.

Next was from the Pennymachines UK site. This thread contains more information along with wiring photos that may help you.

That's my thread so that won't help unfortunately.
I've searched the web about this machine for several months and I haven't found anything I'm looking for, there is pretty much nothing available for this machine so I'm hoping someone has one like this that can take pictures for me or that has schematic

Oops didn't see that one from the Penny Arcade!
What about the post from NLG?

That didn't really help either unfortunately

I'll PM a couple of the other guys here.

Ok thank you!
I think David B Fowler maybe? Had one of these 10 years ago on this forum

I put an excerpt from richard bueschel's "jennings volume 2" book for the "electronic galaxy" models in https://bingo.cdyn.com/slots/jennings/ ... as usual it's too big to post here. 

The list may help you find other machines and there's other useful info in there.

looks like the voltages out of the transformer should be 50V and 6V. 

typically on machines like these the transformers could be wired for 110V (115/120V) or 220V, and a center tap was available for the 220V to connect to the fuse so the game internally had the 110V available for the hopper motor.

the games usually had a common secondary/neutral for the 50V and 6V, so it's possible the green jumper wire on your transformer is the neutral.  You'd probably want to remove the other jumper and measure resistances between other lugs to try and figure it out before connecting some power and measuring voltages.  You could connect a lower voltage AC to what you think is the primary winding and check voltages on other lugs.  An AC adapter for a laptop would work, and the secondary voltages would be proportional

if I had to guess, I'd see if:

lugs 1,5 : 220V input
lug 3: 110V center.  When using 110V input, the jumper shorts/bypasses half the winding 220V winding.
lug 7,10 : common for 6V and 50V with jumper attached
lug 2: 6V
lug 9: 50V

lug 2 and 9 voltages could be swapped.

make sense?

Thank you very much! Much appreciated! That pdf will be great to look at while moving forward
Here is how the transformer looks

[The Swede]

I looked at the schematic in there that you meant but the Jennings only have 2 lugs up top so that means only 1 voltage output maybe? I will measure the windings when I get the transformer, the old one was bad so I bought one from ebay. Fingers crossed it works 😅

[wolftalk]

below is the picture you posted on pennyarcade.  Note the numbers under/over the solder lugs.  You don't have lugs at positions 4,6 and 8

I'm guessing lugs 1,3,5 are the primary winding.  Which lugs you use/jumper depends on your input power, which for you is 230V.  If you remove the jumper between lugs 1,3 and measure the resistance between 1-3, 1-5, and 3-5, if 1-3 and 3-5 is the same and 1/2 the resistance of 1-5, then you'd likely put your mains wires on lugs 1 and 5 and lug 3 would be the motor common wire.

if lugs 1-3 measures no resistance, then I guessed wrong and you'll have to measure the resistance of all the combinations of lugs to get a better guess.

I haven't seen a schematic for a jennings.  The diagram in the patent application is generic and incomplete for an actual machine.

with the transformer out of the game, you should be able to figure out how to connect your 230V to get 115V, 6V and 50V on various transformer lugs.

the next step would be how to connect those lugs to the fuses and the neutrals.   The 115V neutral is probably one of the wire colors on the hopper motor, and some manufactures used yellow for the 6V/50V neutral.

if you want to email highest possible resolution pictures of your fuse block/wiring, the plugs/wiring and the hopper wiring to slotpics@cdyn.com, I'll stick them on the website with the pdf so people can take a look.

I'm assuming the machine never ran in sweden - or at least not without an external step-down transformer.  If the game was run in sweden on 230V with the existing transformer jumpers, life just got harder.

I'm also assuming there isn't any lugs on the other side of the transformer.

That's the old broken transformer
Ok I will do that🙂👍

[wolftalk]

if you are replacing the transformer, you just need one(s) that can give you 115VAC (probably ... it's possible the hopper motor runs on 50V or 230V), 6VAC and 50VAC

The one I bought is an original with same number for Jennings

[wolftalk]

pics are available in https://bingo.cdyn.com/slots/jennings/

looks like you have some modifications - wiring outside a tied harness is always suspicious.  Might take some reverse-engineering to figure out what is going on.

Wich one looks modifyed?😅
