I have no idea about pin numbers; Sega didn't really do a good job with
labeling the board pins or connector pins or keying the connectors...my FAQ
covers the correct hookup for these. All I know is for 4-pin sound
connectors, ground/shiled wires go nearest the card cage.

One end of resistor goes to leg 3 of 10k pot...the other end goes to the
shielding/gnd

Does not sound good, something is wrong; probably not the sound board,
though. More likely the CPU or XY pair are causing a problem. Make sure
the voltages are all good.

This is regular behavior for test mode, though seeing the picture would
help...

This should be covered in my Sega XY FAQ:

Sounds like you have it correct.

I haven't ever hooked up a Sega XY set to a WG6100, but I would suspect the
necessary info would be in this document:
