Starting System: Description and Operation

M/T Models

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
^ through terminal (5) of the ignition switch
^ to clutch interlock relay terminal (3)
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 theft warning relay terminal (1).
With the ignition switch in the START position, power is supplied
^ through 7.5 A fuse [No. (33), located in the fuse block (J/B)]
^ to theft warning relay terminal (3).
If the theft warning system is not triggered, power is supplied
^ through theft warning relay terminal (4)
^ to clutch interlock relay terminal (1).
When the clutch pedal is depressed, ground is supplied to clutch interlock relay terminal (2) through the clutch interlock switch and body grounds (M13), (M73) and (M103).
The clutch interlock relay is energized and power is supplied
^ from terminal (5) of the clutch interlock relay
^ 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 clutch interlock relay is interrupted.

A/T Models

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 theft warning relay terminals (1) and (3).
Also, with the ignition switch in the START position, power is supplied
^ from ignition switch terminal (5)
^ to inhibitor relay terminal (6)
If the theft warning system is not triggered, power is supplied
^ through theft warning relay terminal (4)
^ to inhibitor relay terminal (1)
Ground is supplied, with the selector lever in the P or N position
^ to inhibitor relay terminal (2)
^ through inhibitor switch.
The 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 switch is interrupted.
