DescriptionINFOID:0000000001724477
The terminal “2” (L) circuit controls the charge warning lamp. The charge warning lamp illuminates when the
ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine run-
ning, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a
malfunction is indicated.
Diagnosis ProcedureINFOID:0000000001724478

S TERMINAL CIRCUIT
DescriptionINFOID:0000000001724479
The output voltage of the generator is controlled by the IC regulator at terminal “3” (S) detecting the input volt-
age. Terminal “3” circuit detects the battery voltage to adjust the generator output voltage with the IC regulator.
Diagnosis ProcedureINFOID:0000000001724480
1.CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION
Check to see if connector F2 terminal 3 is clean and tight.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair terminal connection. Confirm repair by performing complete Starting/Charging system test.
Refer to Technical Service Bulletin.
2.CHECK VOLTAGE REGULATOR CIRCUIT
Check voltage between generator harness connector F2 terminal 3
and ground.
Does battery voltage exist?
YES >> Refer to CHG-33, "Work Flow".
NO >> Check harness for open between generator and fuse.3 - ground Battery voltage

REMOVAL
1. Disconnect the battery cable from the negative terminal.
2. Remove drive belt. Refer to EM-16, "
Removal and Installation".
3. Disconnect generator connector (1).
4. Remove “B” terminal nut (2) and “B” terminal harness.
5. Remove upper generator bolt (3) and generator lower bolt (4).
6. Remove generator upward from the vehicle.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Be sure to tighten “B” terminal nut carefully.
 Temporarily tighten the generator bolts in order from the lower to the upper, and then tighten them in order
from the upper to the lower.
CAUTION:
For the generator, the front side (pulley side) surface is the reference surface. Fit the reference sur-
face to the generator mating part, and then tighten the bolts.
 Install generator, and check tension of belt. Refer to EM-15, "
Checking".

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001731368
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
