Inspection After Disassembly 

AKS002EP

PINION/CLUTCH CHECK 

1.

Inspect pinion teeth.

●

Replace pinion if teeth are worn or damaged. (Also check condition of ring gear teeth.)

2.

Inspect reduction gear teeth.

●

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 Description 

AKS002EF

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 to alternator terminal 4 (S) through:

●

15A fuse [No. 56, located in the fuse, fusible link and relay block (J/B)].

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 alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied

●

10A fuse [No. 9, located in the fuse block (J/B) No.1]

●

to combination meter terminals 40 and 42 for the charge warning lamp.

Ground is supplied to combination meter terminal 64 through alternator terminal 3 (L). 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 malfunction is indicated.
