DSG-423 STARTER
07-3
GENERAL INFORMATION
Description
The starter motor provides the rotation of the engine
crankshaft, through the flywheel, that is needed to start
the engine.
The starter system consists of:
• starter motor
• starter solenoid
• starter relay
• battery.
The starter motor is a permanent magnet, gear
reduction type. It runs on 12 volts DC current. The
starter solenoid is integral to the motor and a relay is
also used. Refer to section 6 for information on the
battery.
Operation
When the ignition is turned to the start position, the
starter relay switches power to the starter solenoid,
causing the starter motor to engage (transmission must
be in PARK or NEUTRAL).
Battery power is always present at the starter motor B+
terminal. The starter motor relay, when energized,
sends current to the starter motor “S” terminal, which
causes the motor’s shaft to rotate. When the starter
switch is released, a spring returns the solenoid to the
released position.
