Testing the continuity of contacts
Test equipment
0 to 20 V dc voltmeter
Test the continuity of contacts as follows:
1. Open the hood.
2. Remove the protective cover (13), the nut (12)
and the cover (14).
3. Connect the voltmeter between motor and sole-
noid negative terminals and operate starter
switch.
4. No voltage indicates a faulty solenoid. Replace
the solenoid.

5. 12 V registered but motor fails to operate indi-
cates faulty motor. Replace the starter motor.
6.12 V registered and motor operates, test the
voltage drop across the contacts.
Testing the voltage drop across the con-
tacts
Test equipment
0 to 20 V dc voltmeter
Test the voltage drop across the contacts as follows:
1. Connect the voltmeter across the solenoid termi-
nals and operate starter switch.
2. Voltage across the terminals should be zero, if
more, the solenoid is faulty and must be
changed.
3. If solenoid is satisfactory, service the starter
motor.
