STARTING SYSTEM
Check for continuity between the commutator and
armature coil core.
If continuity exists, replace the armature.
Check for continuity between the commutator and
armature shaft.
If there is continuity, replace the armature.
Place the armature in an armature tester (commercially
available).
Hold a hacksaw blade close to the armature core. If the
blade is attracted to the core or vibrates when the core
is turned, the armature is shorted. Replace the
armature.
OVERRUNNING CLUTCH
Check the overrunning clutch (1) for smooth axial
(1)
movement.
Clean and apply grease to the spline, if necessary.
If the overrunning clutch does not move smoothly after
cleaning or coated with grease, replace the overrunning
clutch.
