Yeah, but this is NOT brain surgery, nor does justify a dozen posts to the 
reflector. Haul out your wire tables that show resistance per foot for various 
wire sizes, use your VOM to measure the current with a short cable connecting 
the rotor to the controller (or look at the manufacturer's specs for current), and 
use Ohm's law.
