33.7.3 Inspecting the stator coil
1. Check for continuity between lead wires of the
stator coil. If there is no continuity, the stator coil is
suspected to be broken. Replace the stator coil.
2. Check for continuity between each lead wire and
stator core. If any continuity is found, the stator coil
is suspected of grounding. Replace the stator coil.
33.8 Assembly of alternator
Reassemble the alternator in the reverse sequence of
disassembly and pay attention to the following:
1. The rear bearing has an eccentric groove. Install
the snap ring so that its protrusion fits to the
deepest part of the groove.
2. When installing a new rear bearing, press-fit the
bearing with its groove facing to the slip ring side.
3. When press-fitting the rear bearing into the rear
bracket, heat the bracket.
CAUTION
Before installing the rotor to the rear bracket, insert a
wire through the small hole in the rear bracket to lift
the brushes. Remove the wire after the rotor is
installed.
