John,
I was not suggesting that a transformer with a shorted winding could be used simply by disconnecting the load from that winding. I was merely trying to suggest a troubleshooting technique. A shorted socket, or other circuit fault can make the transformer look like it has a shorted winding unless disconnected from the transformer.
Are my communications skills that bad?
Rob
Addendum: Oh, I see that you must have been referring to CharlieT's reply. John is right Charlie. If any individual winding within the xfmer has an internal short to itself, the transformer cannot be used at all, unless this short can be found and cut open. Otherwise smoke will come out. Just disconnecting that winding from the circuit won't help.
Sure reduces confusion by addressing people by name don't you think?
