DESCRIPTION
The starting system has (Fig. 1):
• Ignition switch
• Starter relay
• Transmission Range Sensor or Park/Neutral
Switch
• Wiring harness
• Battery
• Starter motor with an integral solenoid
• Powertrain Control Module (PCM)
OPERATION
These components form two separate circuits. A
high amperage circuit that feeds the starter motor up
to 300+ amps, and a control circuit that operates on
less than 20 amps.
The PCM controls a double start over-ride safety
that does not allow the starter to be engaged if the
engine is already running.
