Thanks John, the photo loaded upside down. The next time I'm near the electronic surplus I'll get you some cable. Hopefully they still have it, it was on a spool probably 100s of feet and has 30 wires.

Using that multi-strand wire cable looks like it makes an easy job of making an extention cable. I bought a bunch of 18 gauge wire when I built mine. Made mine all 6ft long. I still need to make a couple 30 cords

Checked the female side of the cinch plug and it looks to be fine.
But in the process I have realised more parts are missing from the door. Argh...

The latching mech has been removed (not overly concerned about replacing, would be nice).

And the coin reject switch has been removed as well. (looks like the wires are still in harness)

Found a Aussie 5c coin mech one of my local suppliers had stashed away!

Until I get the hopper cinch-plug this project will have to be on hold. A massive thanks must go out to all that have contributed on the forum. Especially Jon (ovenguy10) who has been awesome, I can't thank him enough, without his help this project would have sat idle for a lot longer. Thanks Jon.

I will be back with some updates once the parts have arrived.

And for anyone interested. My background is in PCB repairs as a hobbyist (pinball, arcade and anything in-between). This is the first Bally machine I have ever worked on; done a few aristocrats, but this older tech I must admit is a lot more fun, some really clever stuff the designers have done. (I was born around the time intel released the 80286, so a lot of this is new to me)

Wow you're just a kid I was born when we had vacuum tubes and more vacuum tubes

Hey All,

Parts arrived (Thanks Jon!). The gearbox is now free on hopper and the new cinch connector is installed.
Some progress at least...

DavidLee · « **Reply #66 on:** February 22, 2016, 07:23:13 AM »

Making progress, that's good. What's next?

nauseous · « **Reply #67 on:** February 23, 2016, 12:33:18 AM »

Got these today. Need one for under the lowest coin chute. Need to install and mark throw, then bend accordingly. Quick and easy one really.
After that just need to install the lockout armature (thanks jon) under coil.

Then it's time to fire it up with all the parts installed. Have rebuilt reel mechanism and hopper, so everything should be happy days (in that regard).

Wiring Question:

The other side of the molex plug shown earlier. Orange wire is 50V and brown wire goes to lower coin switch on front door.
Orange wire runs to switch on rear of hopper - what is the name of this switch so i can ID in schematic? I assume this is the 50v input for the hopper?

Jon · « **Reply #69 on:** March 06, 2016, 09:33:16 AM »

the switch on the hopper is the zero set switch

the molex plug goes to the coin to cash box meter on your schematic

Jon · « **Reply #70 on:** March 07, 2016, 04:44:42 AM »

ok the molex connector in your hand goes to a meter like the one circled in this picture of which would mount to the bracket circled in the other part of the picture your meter is missing on the machine does not matter...

I will go up to the shop when the rain breaks and look at the schematic I believe that one is like an 8 91 and I will talk you through wear that red black wire goes it goes up to the real machine

the black white wire on that switch should go to a solenoid almost directly behind it. Also has a 70 orange wire going to it

Jon · « **Reply #71 on:** March 07, 2016, 05:04:33 AM »

take the schematic down and have it printed it will be much easier

I believe this is what you're looking for on the schematic I will get the original out and see what that wire is supposed to be

nauseous · « **Reply #72 on:** March 07, 2016, 01:22:41 PM »

Thanks Jon; this was the molex connector that runs to the set zero pay switch.
I have now terminated it onto the cinch plug. Alas couldn't find the other end, ID'ing the switch for me in that schematic is a good help.

Jon · « **Reply #73 on:** March 07, 2016, 01:56:43 PM »

I have seen wires in the harness shorted and people put wires and Molex connectors like that this is where it goes to on the real machine

nauseous · « **Reply #74 on:** March 09, 2016, 02:32:04 AM »

Unfortunately the reel unit wiring looks a little different to the one in your photo... I don't have a common wire between all 3 switch banks.
And it seems to have an extra switch in position B..?

Jon · « **Reply #75 on:** March 09, 2016, 08:06:26 AM »

yes but knowing the wiring that orange black wire at the hopper goes to that orange black wire on the real machine Chase it down it is cut off somewhere or disconnected somewhere for some reason between the real machine and the hopper that is where the wire goes right there to the B switch

OldReno · « **Reply #76 on:** March 09, 2016, 01:00:43 PM »

You don't need a common wire between all switch banks. They each have their own functions.
Also, the extra stack on your 'B' switch I would bet goes to a resettable win meter, probably somewhere on the door so it can be seen by customer.

nauseous · « **Reply #77 on:** March 09, 2016, 01:04:10 PM »

OK so tracing the orange/black wire from reel through harness it runs to the credit board (100 terminal) on hopper..

OldReno · « **Reply #78 on:** March 09, 2016, 01:18:57 PM »

Use your meter, don't just use your eyes, sometimes the same color wire is used twice in the machine.
I recall the 100 pay wire being a black/red trace....

?
It makes little sense having the 100 pay wire go through the hopper reset B switch, as pays are disabled during reel spin, which is when that switch closes.

nauseous · « **Reply #79 on:** March 09, 2016, 01:35:41 PM »

Yeah i buzzed it out with a multimeter.
I still suspect the hopper is from a different machine.

So where should the 100 pay wire terminate on the reel ?
