Diagnosis Procedure
INFOID:0000000010431022
1.
CHECK “B” TERMINAL CONNECTION
1.
Turn ignition switch OFF.
2.
Check if “B” terminal is clean and tight.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair “B” terminal connection.
2.
CHECK “B” TERMINAL CIRCUIT
Check voltage between alternator “B” terminal and ground.
R9M engine
HR engine
K9K engine
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Check harness for open between alternator and fusible link.
3.
CHECK “B” TERMINAL CONNECTION (VOLTAGE DROP TEST)
1.
Start engine, then engine running at idle and warm.
2.
Check voltage between battery positive terminal and alternator “B” terminal.
