How to Handle BatteryNKS00006
CAUTION:

If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.

After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging
a battery.

The battery surface (particularly its top) should always be kept
clean and dry.

The terminal connections should be clean and tight.

At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.

When the vehicle is not going to be used over a long period of
time, disconnect the battery cable from the negative terminal.

Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.

CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Remove the cell plug using a suitable tool.

Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.

CHARGING THE BATTERY
CAUTION:

Never “quick charge” a fully discharged battery.

Keep the battery away from open flame while it is being charged.

When connecting the charger, connect the leads first, then turn on the charger. Never turn on the
charger first, as this may cause a spark.

If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Always charge battery
at a temperature below 55 °C (131 °F).
Charging Rates
Never charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps
indicated above refer to initial charge rate.

If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be
replaced.

3. CHECK GROUND CIRCUIT STATUS (VOLTAGE DROP TEST)
1. Turn ignition switch OFF.
2. Shift A/T selector lever to “P” or “N” position. (A/T models)
Keep depressing clutch pedal fully. (M/T models)
3. Check voltage between starter motor case and battery negative
terminal.
OK or NG
OK >> “B” terminal circuit is OK. Further inspection necessary. Refer to SC-13, "Trouble Diagnoses with
Starting/Charging System Tester (Starting)" .
NG >> Check the starter motor case and ground for poor continuity.

Check “S” Connector Circuit
CAUTION:
Perform diagnosis under the condition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.

CHARGING SYSTEM
Revision: 2006 November2007 350Z
CHARGING SYSTEMPFP:23100
System DescriptionNKS0000E
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. 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 charging circuit is protected by the 140A fusible link (letter A , located in the fusible link holder).
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 23 for the charge warning lamp.
Ground is supplied with power and ground supplied

to terminal 17 of combination meter

through alternator terminal 3 (“L” terminal)

through case ground.
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.
