INSPECTION AFTER DISASSEMBLY
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

NKS000F2

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

●

10A fuse (No. 36, located in the fuse and fusible link block)

●

to alternator terminal 4 (“S” terminal).

“B” terminal 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” terminal) 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

●

through 10A fuse [No. 14, located in the fuse block (J/B)]

●

to combination meter terminals 22 and 23 for the charge warning lamp.

Ground is supplied

●

to combination meter terminal 41

●

through alternator terminal 3 (“L” terminal)

●

to alternator terminal 2 (“E” terminal)

●

through grounds E212 and E213.

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.

MALFUNCTION INDICATOR

The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

●

Excessive voltage is produced.

●

No voltage is produced.

Trouble Diagnosis with Battery/Starting/Charging System Tester (Charging)

NKS000F4

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done
as a set from start to finish.
Before starting, perform the preliminary inspection. Refer to 

SC-26, "PRELIMINARY INSPECTION"

 .

1.

Turn off all loads on the vehicle electrical system.

2.

Perform battery and starting system test with Battery/Starting/
Charging system tester.

3.

Press “ENTER” to begin the charging system test.

4.

Start engine.

5.

Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.

6.

Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.

NOTE:

●

If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.

●

Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect
this without any other action being taken. If this occurs, con-
tinue on with the testing process. The final results will not be affected.

7.

The tester now checks the engine at idle and performs the
“DIODE/RIPPLE” check.

8.

When complete, the tester will prompt you to turn on the follow-
ing electrical loads.

●

Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.

●

Headlamp high beam

●

Rear window defogger

NOTE:
Do not run the windshield wipers or any other cyclical loads.

9.

Press “ENTER” to continue.
