d. Motor Windings (Compressor, Blower, or Fan). Using a multimeter set to measure continuity, check continuity
between the associated contactor output terminals T1, T2, and T3. Continuity should be indicated by a nominal
resistance reading between any combination of these terminals. Check continuity between each of these
terminals and the FDECU frame (ground). No continuity should be indicated. Note that if a motor winding shows
a dead short (no resistance) or open condition the interconnecting wiring or connectors could be damaged and
not the motor.
