BadO/L:
Little or infinite ohm reading (no needle movement)
between pins 43 and 44, 43 and 45 Set multimeter to
ohms
Standard readings:
Between pins 44 and 45 = 11 ohms
Between pins 44 or 45 and 43 = 55 ohms
Open Winding:
Infinite ohms (no needle movement) between pins 44
and 45 Check between pins 44 and 43 or 45 and 43 to
determine which winding is open
Mechanical Binding:
Motor hums Motor leads show continuity between all
windings Shaft does not move Reads 65 amps at pin 43
on both rotations
