System DescriptionNJSC0004M/T MODELSNJSC0004S01Power is supplied at all times
+through 40A fusible link (letterB, located in the fuse and fusible link box)
+to ignition switch terminal 1.
With the ignition switch in 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 MODELSNJSC0004S02Power is supplied at all times
+through 40A fusible link (letterB, 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 ON or START position, power is supplied
+through 10A fuse [No. 20, located in the fuse block (J/B)]
+to park/neutral position (PNP) 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
+from 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.
STARTING SYSTEM
System Description
SC-13

System DescriptionNJSC0009SEDANNJSC0009S01The 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 to alternator terminal 4 (S) through:
+10A fuse (No. 33, located in the fuse and fusible link box).
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 80A (A/T models with QG13DE engine and M/T models with gasoline engine) or 100A (A/T models
except QG13DE engine and diesel engine models) fusible link.
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. 30, located in the fuse block (J/B)]
+to combination meter terminal 17 (Models with tachometer) or 22 (Models without tachometer) for the
charge warning lamp.
Ground is supplied to terminal 62 (Models with tachometer) or 61 (Models without tachometer) of the combi-
nation meter through terminal 3 (L) of the alternator. With power and ground supplied, 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 fault is indicated.
HATCHBACKNJSC0009S02The 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 to alternator terminal 4 (S) through:
+10A fuse (No. 33, located in the fuse and fusible link box).
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 80A (Gasoline engine models without daytime light system) or 100A (A/T models, diesel engine mod-
els and gasoline engine models with daytime light system) fusible link.
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. 30, located in the fuse block (J/B)]
+to combination meter terminal 40 or 1
Ground is supplied to terminal 1 or 28 of the combination meter through terminal 3 (L) of the alternator. With
power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing suffi-
cient 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 fault is indicated.
