S TERMINAL CIRCUIT
DescriptionINFOID:0000000003860527
The output voltage of the alternator is controlled by the IC voltage regulator at the “S” terminal detecting the
input voltage.
The “S” terminal circuit detects the battery voltage to adjust the alternator output voltage with the IC voltage
regulator.
Diagnosis ProcedureINFOID:0000000003860528
1.CHECK “S” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “S” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “S” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “S” TERMINAL CIRCUIT
Check voltage between alternator harness connector and ground.
Is the inspection result normal?
YES >> Refer to CHG-2, "Work Flow".
NO >> Check harness for open between alternator and fuse.

 Temporarily tighten all of alternator bolt and nuts. And then
tighten them in numerical order shown in the figure.
 Be sure to tighten “B” terminal nut carefully.
 Install alternator and check tension of belt. Refer to EM-12, "
Checking".
 For this model, the power generation voltage variable control system that controls the power gener-
ation voltage of the alternator has been adopted. Therefore, the power generation voltage variable
control system operation inspection should be performed after replacing the alternator, and then
make sure that the system operates normally. Refer to CHG-20, "
Inspection Procedure".
Disassembly and AssemblyINFOID:0000000003860540
DISASSEMBLY
Rear bracket assembly
NOTE:
Rear bracket assembly may be hard to remove because a ring is
used to lock outer race of rear bearing. To facilitate removal of rear
bracket assembly, heat only the bearing box section until the temper-
ature increases to approximately 30°C (86°F) with a soldering iron
(200W capacity).
CAUTION:
Never use a heat gun, as if can damage diode assembly.
Front Cover
1. Set rotor to the vise.
CAUTION:
 Be careful not to damage the rotor.
 Use copper plate or thick cloth for rotor in the vise.
2. Remove pulley cap, using suitable tool.

3. Remove alternator pulley, using alternator pulley adaptor (A)
[SST:KV10118200].
ASSEMBLY
Rear Bearing
CAUTION:
 Never reuse rear bearing. Replace with a new one.
 Never lubricate rear bearing outer race.
Rear bracket assembly Installation
1. Fit brush assembly, diode assembly, regulator assembly and
stator.
2. Push brushed up with fingers and install them to rotor.
NOTE:
Take care not damage slip ring sliding surface.

4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to CO-10, "
Flushing".
RefillingINFOID:0000000003793168
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-110, "
Dis-
assembly and Assembly".
2. Check that each hose clamp has been firmly tightened.
3. Remove air duct assembly and air cleaner cases (upper and lower) assembly. Refer to EM-26, "
Exploded
View".
4. Disconnect heater hose (1) at the position ( ) in the figure.
5. Fill radiator, and reservoir tank if removed, to specified level.
CAUTION:
Never adhere the engine coolant to electronic equipments.
(alternator etc.)
Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.
When engine coolant overflows disconnected heater
hose, connect heater hose, and continue filling the engine
coolant.
Use Genuine NISSAN Engine Coolant or equivalent in its
quality mixed with water (distilled or demineralized). Refer
to MA-11, "
Fluids and Lubricants". Tightening torque : Refer to CO-13, "

6. Install air duct assembly and air cleaner cases (upper and lower) assembly. Refer to EM-26, "Exploded
View".
7. Install radiator cap.
8. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at
3,000 rpm.
 Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
9. Stop the engine and cool down to less than approximately 50°C (122°F).
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
CAUTION:
Never adhere the engine coolant to electronic equipments. (alternator etc.)
10. Refill reservoir tank to “MAX” level line with engine coolant.
11. Repeat steps 7 through 10 two or more times with radiator cap installed until engine coolant level no
longer drops.
12. Check cooling system for leakage with engine running.
13. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to
3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
 Sound may be noticeable at heater unit.
14. Repeat step 13 three times.
15. If sound is heard, bleed air from cooling system by repeating step 5, and steps from 7 to 14 until engine
coolant level no longer drops.
