STARTER MOTOR INSTALLATION

1. Inspect and replace starter motor O-ring if needed.
2. Lubricate starter motor O-ring with fresh engine oil.
3. Install the starter motor onto the engine case.
4. Hand tighten the upper starter mounting bolt / stud.
5. Install and torque the upper mounting bolt to
specification.
NOTICE
Tighten the upper starter bolt first, as the upper hole
acts as a pilot hole to properly align the starter drive
(bendix) with the flywheel. This helps prevent binding
and starter damage.
6. Torque lower starter mounting screw to specification.
7. Install (-) negative battery cable to the upper starter
mounting bolt / stud. Torque nut to specification.

STARTER SOLENOID BENCH TEST

Test the start solenoid by powering the solenoid using
battery voltage for a maximum of 5 seconds. With the
solenoid energized, resistance should read about 0 - 0.5
ohms between terminals (A) and (B). If resistance
measurement is out of specification, replace the starter
solenoid.

STARTER SOLENOID OPERATION

To energize the Starter Solenoid the following must
occur:
• The brake must be applied to provide a ground path
via the Orange wire.
• The key switch must be turned to the "start" position to
provide 12V power via the Green / White wire.
• Once the pull-in coil is energized, the solenoid
provides a current path for 12V power to reach the
starter motor.
