I've been working on the Cyber Lead entry on the GameSX wiki, and it's getting to be fairly comprehensive. It's wild to me how many different connectors are in use in this thing. JST (three different series!), Molex and AMP/TE... Like they owed everyone a favour when they did the wiring. Fully bizarre.

The wiki page now has pinouts and part numbers for most of the connectors in the cab.

@NFGx Any idea why the main controls harness has buttons 1-6 and then the extra button harness has 4-6? Maybe this is why my buttons are playing up after the restoration - I don’t need to plug in the extra button harness.

Well, the JVS I/O encoder, takes the 1-6 buttons and pumps them down the serial line to the board in the basement.

Whatever's down there does its own thing with the buttons. In the case of the JAMMA adaptor, it breaks the 4-6 out to a second connector because JAMMA doesn't support all six.

So the 'kick' buttons almost always have a second connection. Unless you're China and just use whatever pin you feel like. ;)

Right, so if I was using jvs only then the main buttons connector would do? You say serial but this is via the usb connectors right? I didn’t think the d-subs were serial?
 
JVS is serial communication using the USB cabling, yeah.

I'm not 100% sure what you're referring to when you say 'main buttons connector'. If you're only using JVS, then you've got all buttons to the encoder under the panel, a cable to the JVS receiver in the base of the cab. That's all you need, yes.

If you're using something else, like a CPS2 or Tekken board, you use the JAMMA/JVS to connect the JAMMA edge and the kick harness.
 
Sorry it’s a bit confusing I know. I don’t quite get why there’s a kick harness when the full 6 button signals are sent to the jvs/Jamma converter down the usb anyway. It’s obviously just now they had to design it. I’m going to be using Mistercade, but in my input testing with a Jamma test pcb which supports button 1-6 testing I’ve got various weird double button presses - the coin counter ticks over on one button, the speaker buzzes on another button press. I’ll try swapping usb cables and/or unplug the extra buttons harness.

The JAMMA connector has 3 buttons, with buttons 4 and 5 using two pins that don't have a defined function. They're for whatever the board needs. Button six uses one of the JAMMA connector's ground pins. This use of the ground pin for B6 is often called 'CHAMMA" because it's a weird Chinese use of the JAMMA connection.

The USB cable isn't likely to be the problem, if it works at all it should be working without that sort of issue. I'd love some more details about your setup. Are you going panel -> JVS in -> JVS out -> CHAMMA ? What board are you testing with?

Thanks. It was all working before with Demon Front which uses three buttons. I recall the extra button harness wasn’t connected (not required). A previous owner cut a bunch of wires - button 4,5 & G and spliced them directly into the buttons - which sounds like they were using a chamma multi board maybe. But should one of those boards work on the Cyberlead if the extra button harness is plugged in? I’ve rejoined the wires and was testing with the tester in the attached pic. Working through this is helping thanks.

That JAMMA connector will absolutely not be passing all the buttons to that board. The Jamma/JVS board sends only 1-3 to the JAMMA connector, 4-6 are only on the kick harness. Since your kick harness isn't plugged into that board... I can see there's something plugged into it. Where does it go?

That kick harness connector on the board in your photo is OUTPUT ONLY. It goes to the game board. Whatever else you're connecting it to is wrong. I think we found your problem. ^__^

It’s going into the IO board.

That's wrong. The JVS I/O board runs all panel signals to the JAMMA adaptor board. The kick harness plug you're using connects to the JAMMA board, it doesn't go back up to the panel bay. You're treating it as an input. It's an output.
 
Cool thanks. I’ll change that tomorrow. So what plugs into the IO board once it’s removed? What is the purpose of that connector?

I’m assuming then I’ll remove the plug from the IO and plug it into the kick harness connector on the test board.

Thanks so much @NFGx - it was plugged in there when I got the machine so that threw me. Thanks for the link. I didn’t see that anywhere on the cyber lead page on Arcade Otaku. I’ll report back tomorrow how it goes. 👍🏼
 
Yes, that's the place you want to plug it in. BUT! I don't know the pinout of that connector. It would be weird in nine ways if it was the same as the JAMMA/JVS board. I can't find the details on the website you linked. Did it come with a manual?

Kind of irrelevant honestly - you'll need to use a Capcom compatible kick harness for your mistercade. So Namco 10pin < - > Capcom kick connector.

Okay I’ll take care. The pinout on the test board is the same as an SF2 kick harness. So the namco 10 pin would have originally gone to a namco board would it - that required extra buttons?
 
I think it was more general purpose. I don't know of many six button Namco games off the top of my head. Soul Calibur and Tekken were four button games...
 
I discovered the the V MINI cable originally went to a board that shipped with the cabinet. The manual says to remove it and then put in a JVS PCB and plug everything else back in except the EL connector. So that explains the left over cable. I’m guessing they had to ship the cabinet with some very rudimentary game in it perhaps?

That seems to ring a bell, yeah. All the manufacturers did that at one point, I think.

Geez if it's not used for anything I might as well cut it in half and wire up my kick harness with it. But I just ordered eighty bucks worth of parts to build one from scratch. =/

Funny stuff. Me too but over $100 bucks worth because I want have CPS 1 and 2 connectors - but could I get them all from the one place? No. Had to go to RS and Mouser.
