thanks all for your input. I know the short is in an unaccessible place, I have isolated it to the wiring passing through the sandwiched ceiling structure. I have disconnected all of that circuits output wiring from the converter and physically followed it from the converter all the way to the ceiling area. There is an access hole in a cabinet where it passes into the ceiling. The wiring can not be pulled out in either direction, they are stuck in the ceiling, its only a 4' run, but they are stuck and wont budge in either direction. And I've tried to see if I can fish a wire through, but the ceiling sandwiched structure is filled with foam, so no go. So its battery powered led light fixture or run a wire on the ceiling and cover it with a trim piece. Thanks all for your input.
