TESTING - CONTINUED
12.
To test stator assembly (10) for open or grounded
10
windings, use a multimeter set to ohms, low scale,
measure resistance through stator windings. Connect
61
multimeter to terminal clips (61 thru 63), from each
outside clip to center clip and then between two out-
62
side clips.
13.
Measure resistance from each terminal clip (61 thru
63) to stator frame to check for grounded windings. A
63
low resistance reading between any terminal clip and
stator frame indicates a grounded winding, and stator
(10) must be replaced as a unit.
