Starting System: Description

2000 Saturn LW1 AutomaticSECTION Description

Cranking circuit consists of battery, ignition switch, starter/solenoid, clutch start switch (M/T), transaxle position switch (A/T) and related wiring. When ignition switch is turned to START position, starter solenoid windings are energized. This causes plunger to move shift lever, which engages pinion with engine flywheel ring gear. Movement of plunger also closes main contacts, applying battery voltage to starter.

When engine starts, pinion will overrun, protecting armature from excessive speed and flywheel from damage. When ignition switch is released, plunger return spring disengages pinion.
