2004 NISSAN TERRANO Service Repair Manual

Trouble Diagnoses
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.
IBefore starting, inspect the fusible link.
I Use fully charged battery.
WITH IC REGULATOR
NOTE:
IIf 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
The IC regulator warning function activates to illuminate ªCHARGEº warning lamp, if any of the following
symptoms occur while alternator is operating:
IExcessive voltage is produced.
I No voltage is produced.

Disassembly
REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used to
lock outer race of rear bearing. To facilitate removal of rear
cover, heat just bearing box section with a 200W soldering
iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARING
CAUTION:
IDo not reuse rear bearing after removal. Replace with a
new one.
I Do not lubricate rear bearing outer race.
Inspection
ROTOR CHECK
1. Resistance test
Resistance: Refer to SDS (SC-30).
I Not within the specified values ... Replace rotor.
2. Insulator test
I Continuity exists ... Replace rotor.
3. Check slip ring for wear. Slip ring minimum outer diameter:Refer to SDS (SC-30).
I Not within the specified values ... Replace rotor.
BRUSH CHECK
1. Check smooth movement of brush.
INot smooth ... Check brush holder and clean.
2. Check brush for wear.
I Replace brush if it is worn down to the limit line.

STATOR CHECK
1. Continuity test
INo continuity ... Replace stator.
2. Ground test
I Continuity exists ... Replace stator.
Assembly
RING FITTING IN REAR BEARING
IFix ring into groove in rear bearing so that it is as close to the
adjacent area as possible.
CAUTION:
Do not reuse rear bearing after removal.
REAR COVER INSTALLATION
1. Fit brush assembly, diode assembly, regulator assembly and stator.
2. Push brushes up with fingers and install them to rotor.
Take care not to damage slip ring sliding surface.
