Removal and InstallationNKS0000C
REMOVAL
1. Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.
CAUTION:
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.
2. Remove engine undercover, using power tools.
3. Disconnect steering lower joint (1), then remove it. Refer to PS-
17, "REMOVAL" .
4. Remove “B” terminal mounting nut (A).

Disassembly and Assembly NKS0000D
TYPE: S114-928
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.

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.
