CHARGING SYSTEM

System Description
NKS001MK
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
●
through 10A fuse (No. 33, 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 terminal 20 for the charge warning lamp.
Ground is supplied
●
to combination meter terminal 4
●
through alternator terminal 3 (“L” terminal)
●
to alternator terminal 2 (“E” terminal)
●
through ground E29.
With power and ground supplied, the charge warning lamp will illuminate. When the alternator is providing suf-
ficient 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)
NKS001MM
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-22, "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.

10. 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 be displayed. Press
“ENTER” to restart the test.
11. Diagnostic result is displayed on the tester. Refer to
"DIAGNOSTIC RESULT ITEM CHART"
.
12. Press “ENTER” then test output code is displayed. Record the
test output code on the repair order.
13. Toggle back to the “DIAGNOSTIC SCREEN” for test results.
