You are reading voltage

---but describing a continuity check. I assume this is inadvertent on your part--or I'm misreading what you're saying. Anyway, be sure that your are indeed reading resistance and not a "ghost voltage".
Secondly, look down the barrel of the BNC with a really good light and be sure a big aluminum chip--or some other conductive material--isn't shorting the pin to the barrel. Once saw a piece of aluminum foil do this. Very hard to see if it's pressed flat in the bottom.
Sincerely hope it's something simple--outside the tank.
