6-3. ALTERNATOR - REPAIR/TEST (Contd)
d. A high (infinite) resistance
reading in STEP c indicates an open
rotor winding and rotor (7) must
4. TEST STATOR (8) FOR OPEN OR GROUNDED
a. Using an ohmmeter set to low scale,
measure resistance through stator
windings. Connect ohmmeter to
terminal clips (17), from each
outside clip to center clip and
then between two outside clips.
b. Measure resistance from each
terminal clip (17) to stator frame
to check for grounded windings. A
low resistance reading between any
terminal clip (17) and stator frame
indicates a grounded winding, and
stator (8) must be replaced as a
1. INSTALL ROLLER BEARING (39) TO SLIP
RING END FRAME (5).
a. Press new roller bearing (39) into
slip ring end frame (5) from
outside to inside, to a depth of
7/32 inch as shown.
b. Fill plug (40) with Delco-Remy
lubricant to a level sufficient to
fill grease reservoir
approximately one-half full.
c. Install plug (40), making sure that
some lubricant touches roller
d. Press new seal (41) into slip ring
end frame (5) bore to a depth of
3/16 inch, as shown.
