Starting System: Description and Operation

Power is supplied at all times:
^ through 30 A fusible link (letter (h) ,located in the fuse and fusible link box)
^ to ignition switch terminal (1).
With the ignition switch in the START position, power is supplied:
^ from ignition switch terminal (5)
^ to inhibitor relay terminal (7)
With the ignition switch in the ON or START position, power is supplied:
^ through 10 A fuse (No. (30) ,located in the fuse block)
^ to inhibitor switch terminal (2).

For models with theft warning system
With the selector lever in the park ("P") or neutral ("N") position, power is supplied:
^ from inhibitor switch terminal (1)
^ to theft warning relay terminal (4)
^ through theft warning relay terminal (3)
^ to inhibitor relay terminal (1).
If the theft warning system is triggered, ground is supplied to theft warning relay terminal (1). This removes power from theft warning relay terminal (4), which disengages the inhibitor relay and the starter motor will not operate.

For models without theft warning system
With the selector lever in the park ("P") or neutral ("N") position, power is supplied:
^ from inhibitor switch terminal (1)
^ to inhibitor relay terminal (1).
Ground is supplied to inhibitor relay terminal (2), through body grounds (E3) , (E14) and (E53).
With power and ground supplied, the inhibitor relay is energized and power is supplied:
^ from inhibitor relay terminal (6)
^ to starter motor windings terminal (1).
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor.
The starter motor is grounded through the engine block. With power and ground supplied, cranking occurs and the engine starts.
