Coin 1

That's the thing, it doesnt work properly with just a button as Coin 1.  If I have a button connected to the 'Coin 1' slot in the Jamma cable or I have the wire cut 8 inches from the Jamma connector, regardless, this damn thing registers a '1' value as if it is always activated.  'Coin 1' is in no way connected to the coin mechanism itself that I can see. 

Its weird that when I run a wire from the 'Coin 2' slot to a button it works perfectly, if I cut that wire and dont attach a button, it registers a '0'.   That makes me think that somewhere in this game something else affects player 1's credits in some way besides the 'Coin 1' slot in my Jamma cable

If you're registering a "1" with only a bare wire coming off the JAMMA harness, there's something in either the harness, or board, that is causing that "1".

The harness is rather unlikely because it's about 7-8 pins from ground, IIRC.
The first thing I'd check is the Coin 1 pin itself though.
Is there anything near it that could be creating a connection somehow?
(Solder bridge, another bare wire, etc...)

Next, I would try disconnecting the harness, and slap a multi-meter onto the Coin1 pin, and ground.
If you're getting connection, the problem is in the harness; if not, it's in the board.

I don't know what would cause it though?
If it is the board, I'd wait for the other one you have coming, and check it there.

Thanks, you are the man.  I'll do my best to check it out in the next few days, i'll come back if its problematic

Unfortunately all I can offer is general troubleshooting.
Maybe someone else can offer up some game-specific suggestions.

Did you connect the wires to the N/C tab instead of the N/O tab?
