I have a King KT76 transponder I bought about a year ago through e-bay. It has a yellow card, with repair information dated just before I bought it. I had no reason to think it wouldn't work. I haven't wired it yet. I was wiring my Com coax and ohmed it to make sure of no shorts. Then I happened to seen the Xponder cable and just stuck the ohm meter to it. Dead short!!! Replaced the BNC ends on the cable, no help. Pulled the xponder out of the shelf, ohmed the cable input, it was shorted or closed. My question is, is it possible that the coax is normally closed when no power is to it? I pretty sure I know the answer, but just double checking before I take it to a avionics shop.

Yes, it is possible for a coax connected to an antenna to read a dead short at D.C.. It depends on how the feed to the antenna is designed. If the coax is indicating a short with both ends disconnected then you've definitely got a problem. If one end is attached to the antenna then you may or may not have a problem. You'll need to consult with the antenna manufacturer or have a radio shop measure the antenna impedance at the operating frequency it is intended to be used at as several antenna feed schemes will read a D.C. Short but at R.F. Frequencies will exhibit a significant impedance. Don't try and perform that measurement with the transponder (or any radio) connected to the feedline (coax)!
