What's the voltage supposed to be to pin one of connector AB? Is it +12? I'm trying to use one for another monitor, and the schematic just lists the signal as "AS"...
 
So, let's go with a longer question this time:

I built a JAMMA adapter to test DKjr boards. I have the video coming out on the DK side to the inverter board and then from the Invert Out back to the JAMMA side of the adapter, then through the harness to a K7000.

I am using a DKjr board that was tested and found to be working 100% in a DK cab, using the little ribbon cables. I'm using the edge connector and getting no picture. I have voltages on the board in the right range, and have voltage out on the color outputs, to the inverter, and then back out the inverter to the monitor. Power input to the inverter is steady at about 14.4vdc.

Any ideas as to why I don't have a picture?
 
Okay, dug through my big bag of Nintendo cables and found a 10-pin connector cable. Plugged it in and have a perfect picture!

Thanks again.

Now I just have to hook up a quickie computer speaker connection for the sound and I can play on my bench....
