L TERMINAL CIRCUIT (OPEN)
L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000003860523
The “L” terminal circuit controls the charge warning lamp. The charge warning lamp illuminates when the igni-
tion switch is set to ON or START. When the alternator is providing sufficient voltage with the engine running,
the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis ProcedureINFOID:0000000003860524
1.CHECK “L” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “L” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair “L” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2.CHECK “L” TERMINAL CIRCUIT (OPEN)
1. Disconnect alternator connector.
2. Apply ground to alternator harness connector terminal.
3. Check condition of the charge warning lamp with the ignition switch in the ON position.
Does it illuminate?
YES >> “L” terminal circuit is normal. Refer to CHG-2, "Work Flow".
NO >> GO TO 3.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the battery cable from the negative terminal.
2. Disconnect the combination meter connector.
3. Check continuity between alternator harness connector and combination meter harness connector.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair the harness or connector.
4.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check continuity between combination meter harness connector and fuse block.
Is the inspection result normal?
YES >> GO TO 5.

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.
