InspectionEKS00MZH
ROTOR CHECK
1. Resistance test
lNot within the specified values... Replace rotor.
2. Insulator test
lContinuity exists... Replace rotor.
3. Check slip ring for wear.
lNot within the specified values... Replace rotor.
BRUSH CHECK
1. Check smooth movement of brush.
lNot smooth... Check brush holder and clean.
2. Check brush for wear.
lReplace brush if it is worn down to the limit line.
PULLEY CHECK (WITH CLUTCH TYPE)
1. Check for locking (Outer ring is turned counterclockwise when
viewed from the rear).
lIf it rotates in both directions... Replace pulley.
2. Check for dragging (Outer ring is turned clockwise when viewed
from the rear).
lIf it locks or unusual resistance is felt... Replace pulley.
STATOR CHECK
1. Continuity test
lNo continuity... Replace stator.Resistance : Refer to SDS.SC-37,
"Alternator"
