Re: Wiring a desk electric fan.
If you have a multimeter, it may be helpful to measure the DC resistance between each of the wires (after labelling any that aren't otherwise distinguishable from each other). Although this won't necessarily indicate the impedances at 50/60 c/s (Hz), it may at least give some clue as to how it is wired.
