This makes sense if you figure that your test leads, connections to the motor
wires, etc. have 0.5 ohms of resistance (not too far from the 0.4 ohms I
typically see with mine). That gives you about 0.5 ohms for each half of a
winding and 1.0 for the whole thing.

Yes.

Are they identical units? If not, the one with the lower voltage rating is
going to be your limit for the pair.
