If you have a sensitive enough ammeter (clamp on), just open all the breakers. Turn on one at a time until you see a current draw. You could probably go out to the meter and see if the rotor is turning, if yours still has one. Lots of appliances draw some current even when off. You may have to unplug everything to eliminate the trickle.

I think I could make one of those for about three dollars. (Not including meter, but I've got half a dozen meters...) A plug, current sense resistor, and outlet would be all one needs in addition to a meter.
