Starter Solenoid (013-019)
Initial Check
Before troubleshooting the starter motor, make sure the
battery terminals are not loose or corroded. Refer to
Procedure 013-007 and Refer to Procedure 013-009
Voltage Check
Digital Multimeter, Part Number 3377161
Set the digital multimeter, Part Number 3377161, to
measure DC volts.
Connect the multimeter positive (+) lead to the starter
solenoid positive cable terminal and the negative (-) lead
to a chassis or engine ground location.
The multimeter must show voltage with the keyswitch in
the OFF position to be normal.
If the multimeter does not indicate voltage, check the
cable connecting the starter solenoid and battery for
breaks. Also, check for loose or corroded connections.
If the multimeter indicates voltage but the starter will not
operate, check the wire connecting the starter solenoid to
the keyswitch for breaks; and also check for loose or
corroded connections.
In addition, be sure to check for:
• Fuses
• Application engine shutoff systems.
