Models Without Theft Warning System

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 ON or START position, power is supplied
^ through 10 A fuse [No. (17), located in the fuse block (J/B)]
^ to inhibitor relay terminal (1).
Also, with the ignition switch in the START position, power is supplied
^ from ignition switch terminal (5)
^ to inhibitor relay terminal (6)
With the selector lever in the P or N position, ground is supplied
^ to inhibitor relay terminal (2) through the inhibitor switch and body grounds (F18) and (F19).
Then inhibitor relay is energized and power is supplied
^ from ignition switch terminal (5)
^ through inhibitor relay terminals (6) and (7)
^ to terminal (1) of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates. If the theft warning system is triggered, terminal (2) of the theft warning relay is grounded and power to the inhibitor relay terminal (1) is interrupted.
