Dynamic Testing
NOTE: Be sure the engine crankshaft turns freely
before proceeding. Use a digital multimeter during
tests.
Static Testing
1. Remove starter motor and disassemble. (See page
11.11 for exploded view) Mark end covers and
housing for proper reassembly.
2. Remove pinion retaining snap ring, spring and pinion
gear.
3. Remove brush end bushing dust cover.
4. Remove housing through bolts.
5. Slide brush end frame off end of starter.
NOTE: The electrical input post must stay with the
field coil housing.
6. Slide positive brush springs to the side, pull brushes
out of their guides and remove brush plate.
7. Clean and inspect starter components.
NOTE: Some cleaning solvents may damage the
insulation in the starter. Care should be exercised
when selecting an appropriate solvent. The brushes
must slide freely in their holders. If the commutator
needs cleaning, use only an electrical contact cleaner
and/or a non-metallic grit sandpaper. Replace brush
assembly when worn to 5/16, (.8 cm) or less.
Test battery voltage. Is the battery voltage equal to or greater
than 12.8 Vdc?
NO
Remove battery, test and/or service. Install a fully
charged shop battery to continue the test and
continue with left column
YES
Disconnect two-pin harness from starter solenoid. Connect
black multimeter probe to the engine or ground, then the red
probe to the red harness wire at solenoid. Rotate ignition key
to the start position. Meter should read battery voltage. Does
it?
NO
With black tester lead on ground, check for voltage
at large relay terminal, circuit breaker in and out
terminals, and across both sides (red and red/
white) of the ignition switch with switch on start.
Repair or replace any defective parts.
YES
Reconnect the solenoid harness. Connect black probe to
battery positive terminal and red probe to solenoid end of
battery to solenoid cable. Turn key to start position. The
reading must be less than.1V DC. Is it?
NO
Clean battery to solenoid cable ends or replace
cable.
YES
Connect black tester lead to solenoid end of solenoid to
starter cable and red tester lead to starter end of same cable.
Turn key to start position. The reading must be less than.1V
DC. Is it?
NO Replace starter solenoid.
YES
Connect black tester lead to starter frame. Connect red
tester lead to battery negative (-) terminal. Turn key to start
position. The reading should be less than.1V DC. Is it?
NO
Clean ends of engine to battery negative cable or
replace cable.
If all these tests indicate a good condition, yet the starter still fails to turn, or turns slowly, the starter must be remove
for static testing and inspection.
