Coil windings are so short that they have very little DC resistance, so getting a reading with an ohmmeter is all but impossible. However, you could build a simple oscillator (555 timer based) running at ~20kHz. Add a little "current amplifier" to the output (1A max), and hook each motor lead to it with a precision 1ohm resistor in series. The voltage drop on the resistor should be equal on all phases.

In all honesty it kind of has that burnt motor smell . But it's not a very stronge smell .
