Nissan Almera Tino V10. Manual — part 53
System Description
NLSC0009
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 to alternator terminal 4 (S) through:
I
10A fuse (No. 39, located in the fuse and fusible link box).
Terminal B 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) detecting the input voltage. The charging circuit is protected
by the 100A fusible link.
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied
I
through 10A fuse [No. 30, located in the fuse block (J/B)]
I
to combination meter terminal 2
Ground is supplied to terminal 46 of the combination meter through terminal 3 (L) of the alternator. With power
and ground supplied, the charge warning lamp will illuminate. When the alternator is providing sufficient volt-
age 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 fault is indicated.

Trouble Diagnoses
NLSC0011
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspec-
tion Table.
I
Before starting, inspect the fusible link.
I
Use fully charged battery.
WITH IC REGULATOR
NLSC0011S01
SEL338V
NOTE:
I
If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
I
When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace faulty
parts with new ones.
MALFUNCTION INDICATOR
NLSC0011S02
The IC regulator warning function activates to illuminate “CHARGE” warning lamp, if any of the following
symptoms occur while alternator is operating:
I
Excessive voltage is produced.
I
No voltage is produced.
