L TERMINAL CIRCUIT (SHORT)
L TERMINAL CIRCUIT (SHORT)
Description
INFOID:0000000006274872
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 Procedure
INFOID:0000000006274873
1.
CHECK “L” TERMINAL CIRCUIT (SHORT)
1.
Turn ignition switch OFF.
2.
Disconnect alternator connector.
3.
Turn ignition switch ON.
Does charge warning lamp illuminate?
YES
>> GO TO 2.
NO
>> Refer to
2.
CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
1.
Turn the ignition switch OFF.
2.
Disconnect the battery cable from the negative terminal.
3.
Disconnect combination meter connector.
4.
Check continuity between combination meter harness connector and ground.
Is the inspection result normal?
YES
>> Replace combination meter.
NO
>> Repair the harness or connector.

S TERMINAL CIRCUIT
Description
INFOID:0000000006274874
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 Procedure
INFOID:0000000006274875
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
NO
>> Check harness for open between alternator and fuse.
