DIAGNOSIS AND TESTING
Starter Motor Bench Test
Correct starter motor operation can be confirmed by
performing the following free-running bench test. This
test can only be performed with the starter motor
removed from the vehicle.
1. Remove the starter motor from the vehicle (See
Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Mount the starter motor securely in a soft-jawed
bench vise. The vise jaws should be clamped on
the mounting flange of the starter motor (never
clamp on the starter motor by the field frame).
3. Connect a suitable volt-ampere tester and a 12 V
battery to the starter motor in series, and set the
ammeter to the 100 ampere scale.
4. Install a jumper wire from the solenoid terminal to the solenoid battery terminal. The starter motor should oper-
ate. If the starter motor fails to operate, replace the faulty starter motor assembly.
5. Adjust the carbon pile load of the tester to obtain the free running test voltage.
6. Note the reading on the ammeter and compare this reading to the free-running test maximum amperage draw.
7. If the ammeter reading exceeds the maximum amperage draw specification, replace the faulty starter motor
assembly.
Starter Solenoid Test
This test can only be performed with the starter motor removed from the vehicle.
1. Remove the starter motor from the vehicle (See
Starter Motor Removal & Installation in Section 05
Starting and Charging).
2. Disconnect the wire from the solenoid field coil ter-
minal.
3. Check the solenoid for continuity between the sole-
noid terminal and the solenoid field coil terminal
with a continuity tester. There should be continuity.
If there is continuity, go to Step 4. If not, replace
the faulty starter motor assembly.
4. Using a continuity tester, check for continuity
between the solenoid terminal and the solenoid
case. There should be continuity. If not, replace the
faulty starter motor assembly.
