CHARGING SYSTEM

CHARGING SYSTEM PFP:00011
System Description EKS00316
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times

through 10A fuse (No. 34, located in the fuse and fusible link box)

to alternator terminal 4 (S).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (S) detecting the input voltage. The charging circuit is protected by
the 120A (Gasoline engine models) or 100A (Diesel engine models) fusible link (letter A, located in the fuse
and fusible link box).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 11, located in the fuse block (J/B)]

to combination meter terminal 2 for the charge warning lamp.
Ground is supplied with power and ground supplied

to terminal 5 of the combination meter

through alternator terminal 3 (L)

to alternator terminal E (Gasoline engine models) or through body ground (Diesel engine models)

through body ground E30 (Gasoline engine models).
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Power is supplied at all times

through 30A fusible link (letter J, 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 starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
A/T MODELS
Power is supplied at all times

through 30A fusible link (letter J, 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 park/neutral position relay terminal 5.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 13, located in the fuse block (J/B)]

to park/neutral position relay terminal 1.
With the selector lever in the P or N position, ground is supplied

to park/neutral position relay terminal 2

through the park/neutral position switch terminals 1 and 2, and

through body grounds F9 and F10.
Then park/neutral position relay is energized and power is supplied

from park/neutral position relay terminal 3

to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
