Hooking up a "Wei-Ya" (Ultimarc) Coin Selector

[Dreamwriter]

So, I just received my electronic coin selector (and door and lock) from Ultimarc and I am an almost total electronics n00b and can't get it to work.  The internal LED isn't coming on so I think the problem is with power.  This particular coin selector has 4 pins: Counter(+/-), DC+12v, Coin Signal, Ground, Counter(+/-).  What I am doing (for now) is taking the DC+12v cable and just sticking the exposed wire into the yellow-wire molex connector from the computer power supply, and the Ground cable and sticking the exposed wire into the black-wire from the same molex connector.   This of course won't send anything to the computer, but at least should accept coins and light up the internal LED, but it doesn't.

Another thing I was wondering about (and here my n00bness really shows), when connecting the coin wire to the iPAC (actually to an X-Arcade controller), does that need to connect to the ground pin on the coin selector, or can it connect to the ground in the X-Arcade board?  Ground is ground, right?  And where does the Zener Diode go, between the coin wire and coin selector pin?

Thanks!

Does the computer power supply even come on?
I can only assume you are talking about an ATX type power supply?

You may need to jumper pins 14 & 15 on the mother board connector. (which you aren't actually plugging into a motherboard)
Usually the pin with a green wire jumped to the black one next to it.

This is the same power supply the rest of the computer is hooked up to (and it works fine).  I just have one of the power connectors sticking out one of the slots in the back.

Aha, I tried a different power connector from the power supply, and it works!  Well, when I turn on the power, it goes clang, and when I shut down the power the LED blinks.  Now to get it to stop rejecting all coins...

Got it fully working and setup now, thought I'd update this for future electronic n00bs like me   First off, all Ground wires going into the computer power supply go to the same point - including ground from keyboard and mouse jacks.  So yes, you can have the ground from the power supply's molex connector going to the coin box for its power, and the iPac/X-Arcade "button" ground grounding the coin wire.  And while it doesn't make sense to me, the Diode connects directly to the coin wire and ground (at either end), and that does not cause a continual connection.

So my setup is: X-Arcade button wire with two connectors on it (for two buttons going to the same input), end connector connecting to Coin wire from coin accepter, middle connector connecting to one end of the Diode.  X-Arcade ground wire, end connector connecting to other end of Diode.  Coin accepter Power wire going into the yellow-wire (12v) pin of the Molex connector, Coin acceptor Ground wire going into one of the black-wire (ground) pins of the Molex connector.

If it's hooked up correctly, you'll hear a "clang" come from it when the power is turned on.  Oh, and it'll only accept coins if it's mostly level - otherwise it just rejects them (took me a bit to figure that out).

Is it possible to take the front metal cover off this mech?
Can you make some measurements for me? it looks the same size and compatable with a S10 mech gap but i'd want to make sure before I get one.
