1  Determine, with an ohmmeter, which three of the six motor leads are common (one phase). 

2. Label each one of these three motor leads A. 

3. Using the ohmmeter, verify that the remaining three leads are common.

4. Label the remaining three leads B. 

5. Set the ohmmeter range to the 100 ohm scale (approximately). 6. Connect the ohmmeter’s negative lead to one of the motor leads labeled A. Alternately measure the resistance to the two remaining motor leads also labeled A. The resistance measurements will reflect one of the following two scenarios.

Scenario #1 

The resistance measurements to the two remaining motor leads are virtually identical. Label the two remaining motor leads A+ and A–. Label the motor lead connected to the negative lead of the ohmmeter A CENTER TAP (this is the center tap lead for Phase A of the motor). Scenario #2 — The resistance measurement to the second of the three motor leads measures 50% of the resistance measurement to the third of the three motor leads. Label the second motor lead A CENTER TAP (this is the center tap lead for Phase A of the motor). Label the third motor lead A–. Label the motor lead connected to the ohmmeter A+.
