InspectionNJSC0019MAGNETIC SWITCH CHECKNJSC0019S01+Before starting to check, disconnect battery ground cable.
+Disconnect ªMº terminal of starter motor.
1. Continuity test (between ªSº terminal and switch body).
+No continuity ... Replace.
2. Continuity test (between ªSº terminal and ªMº terminal).
+No continuity ... Replace.

PINION/CLUTCH CHECKNJSC0019S021. Inspect pinion teeth.
+Replace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).
+Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
+If it locks or rotates in both directions, or unusual resistance is
evident. ... Replace.

System DescriptionNJSC0009The 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 for Europe without daytime light system) or 100A (Except gasoline engine
models for Europe without 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 1
Ground is supplied to terminal 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 sufficient volt-
age 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.
