DIAGNOSIS AND TESTING (Continued)
tighten the battery cable connection at the solenoid.
Repeat the test. If the reading is still above 0.2 volt,
replace the faulty battery positive cable.

(4) Connect the voltmeter to measure between the
battery negative terminal post and a good clean
ground on the engine block (Fig. 5). Rotate and hold
the ignition switch in the Start position. Observe the
voltmeter. If the reading is above 0.2 volt, clean and
tighten the battery negative cable attachment on the
engine block. Repeat the test. If the reading is still
above 0.2 volt, replace the faulty battery negative
cable.

(5) Connect the positive lead of the voltmeter to
the starter housing. Connect the negative lead of the
Typical
voltmeter to the battery negative terminal post (Fig.
6). Rotate and hold the ignition switch in the Start
position. Observe the voltmeter. If the reading is
above 0.2 volt, correct the poor starter to engine
block ground contact.

If the resistance tests detect no feed circuit prob-
lems, refer to Starter Motor in the Diagnosis and
Testing section of this group.
CONTROL CIRCUIT TESTING
The starter control circuit components should be
tested in the order in which they are listed, as fol-
lows:
• Starter Relay - Refer to Starter Relay in the
Diagnosis and Testing section of this group for the
procedures.
• Starter Solenoid - Refer to Starter Motor in
the Diagnosis and Testing section of this group for
the procedures.
•
Ignition Switch - Refer to Ignition Switch
and Key Lock Cylinder in the Diagnosis and Test-
ing section of Group 8D - Ignition System for the pro-
cedures.
•
Park/Neutral Position Switch - Refer to
Park/Neutral Position Switch in the Diagnosis
and Testing section of Group 21 - Transmission for
the procedures.
•
Wire harnesses and connections - Refer to
Starting System in the Contents of Group 8W -
Wiring Diagrams for complete circuit diagrams.
STARTER MOTOR
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. Refer to Starting
STARTING SYSTEMS 8B - 7
