OK, since I have Will's fully functioning VP, I had a test mule to compare to. No wires are out of place as far as I can see, BUT I do have a strange difference that I believe is the issue or symptom of the issue.
So, on Will's, test continuity from the center lug on a volume pot to each leg of the jack. When volume is on, there is continuity to the hot leg on the jack and nothing on the ground. Turn off the volume and it reverses.
OK, same result on my bridge pot and jack, BUT with volume up on the neck pot, I get continuity to both legs of the output jack. That seems to me that I have a bridge between hot and ground on that pot...I just don't see it.
Help me Mr. Wizard.
