2001 NISSAN ALMERA N16 alternator

Trouble DiagnosesNJSC0011Before 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.
+Before starting, inspect the fusible link.
+Use fully charged battery.
WITH IC REGULATORNJSC0011S01
SEL338V
NOTE:
+If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque.)
+When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary, replace faulty
parts with new ones.
MALFUNCTION INDICATORNJSC0011S02The IC regulator warning function activates to illuminate ªCHARGEº warning lamp, if any of the following
symptoms occur while alternator is operating:
+Excessive voltage is produced.
+No voltage is produced.

System DescriptionNJEL0351The headlamp system on vehicles for North Europe contains a daytime light unit. The unit activates the fol-
lowing whenever the engine is running with the lighting switch in the OFF position:
+Low beam headlamps
+Parking, license, tail and illumination lamps
Power is supplied at all times
+through 10A fuse (No. 38, located in the fusible link and fuse box)
+to daytime light unit terminal 1 and
+to lighting switch terminal 11.
Power is also supplied at all times
+through 15A fuse (No. 39, located in the fusible link and fuse box)
+to daytime light unit terminal 3 and
+to lighting switch terminal 5.
Power is also supplied at all times
+through 15A fuse (No. 40, located in the fusible link and fuse box)
+to daytime light unit terminal 2 and
+to lighting switch terminal 8.
With the ignition switch in the ON or START position, power is supplied
+through 10A fuse [No. 20, located in the fuse block (J/B)]
+to daytime light unit terminal 7.
With the ignition switch in the START position, power is supplied
+through 10A fuse [No. 21, located in the fuse block (J/B)]
+to daytime light unit terminal 6.
Ground is supplied to daytime light unit terminal 9 through body grounds E30 and E73.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)NJEL0351S01When the lighting switch is turned to the 1st or 2nd position, power is supplied
+through lighting switch terminal 12,
+to daytime light unit terminal 11.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATIONNJEL0351S02With the engine running and the lighting switch in the OFF position, power is supplied
+from alternator terminal 3
+to daytime light unit terminal 8,
+through daytime light unit terminal 5
+to terminal 3 of headlamp LH,
+through daytime light unit terminal 4
+to terminal 3 of headlamp RH and
+through daytime light unit terminal 10
+to tail lamp and illumination.
Ground is supplied to terminal 2 of each headlamp through body grounds E30 and E73.
