You're on the right track. The resistance between the rings of the rotor must be between 4 - 6 ohms. Any less and the windings are shorted out and the rotor has to be replaced.

The sad side effect is that the regulator will try to send current to the rotor to excite the stator in excess of its capacity and will frequently fry itself trying to accomplish the impossible.

If the rotor is shorted, check the regulator to make sure its still okay.
