A reading of zero means the fan motor winding is likely shorted and causing the breaker to trip or blow. Create a parallel circuit by placing the leads on. Step 2 test the thermostat. As you probably know fan motors can be designed for several different purposes most common of these are single phase motors.
Once done test that the motor still works by. Look for a resistance reading.
