2.
Inspect reduction gear teeth.
I
Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)

System Description
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
q
S
through:
I
120A fusible link (letter
a
, located in the fuse, fusible link and relay box), and
I
7.5A fuse (No.
62
, located in the fuse, fusible link and relay box).
Terminal
q
B
supplies power to charge the battery and operate the vehicle’s electrical system. Output voltage
is controlled by the IC regulator at terminal
q
S
detecting the input voltage. The charging circuit is protected by
the 120A fusible link.
Terminal
q
E
of the alternator supplies ground through body ground
E112
.
With the ignition switch in the ON or START position, power is supplied
I
through 7.5A fuse [No.
4
, located in the fuse block (J/B)]
I
to combination meter terminal
q
41
for the charge warning lamp.
Ground is supplied to terminal
q
25
of the combination meter through terminal
q
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.
