Hold-In Coil Open Circuit Test
Check for continuity across magnetic switch ‘S’ terminal (1) and
coil case. If no continuity exists, coil is open and should be re-
placed.
BRUSH
Measure length of brushes and replace them as necessary.
Brush length
Limit : 6.0 mm (0.236 in.)
BRUSH HOLDER
Check brush springs for rust or breakage. Also check brush holder
for rust and insulation. Replace it as assembly, if required.
ARMATURE
Ground Test
Between commutator segment and armature core should be in-
sulated. Use ohmmeter for inspection.
Open Circuit Test
Check for continuity between segments. If there is no continuity
at any test point, there is an open circuit and armature must be
replaced.
