CHARGING SYSTEM
CHARGING SYSTEM
System DescriptionINFOID:0000000001704352
The generator 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 generator terminal 3 through
• 10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the battery and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
• to generator terminal 5
• through body ground F5, and
• through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 3, located in the fuse block (J/B)]
• to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes available at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient
voltage, 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.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001704254
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. Information necessary to service the system safely is included in the SR and SB section 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 SR section.
• 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.
Service NoticeINFOID:0000000001704255
• When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
• Handle trim, molding instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.
• Apply sealing compound where necessary when installing parts.
• When applying sealing compound, be careful that the sealing compound does not protrude from parts.
• When replacing any metal parts (for example body outer panel, member, etc.), be sure to take rust preven-
tion measures.
PrecautionINFOID:0000000001704256
• When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
• When removing parts with a screwdriver or other tool, protect parts by wrapping tools with vinyl or tape.
• Keep removed parts protected with cloth.
• If a clip is deformed or damaged, replace it.
• If an unreusable part is removed, replace it with a new one.
• Tighten bolts and nuts firmly to the specified torque.
• After re-assembly has been completed, make sure each part functions correctly.
• Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.
• Do not use any organic solvent, such as thinner or benzine.
