Description
INFOID:0000000001724528
The terminal “2” (L) circuit controls the charge warning lamp. The charge warning lamp illuminates when the
ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine run-
ning, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a
malfunction is indicated.
Diagnosis Procedure
INFOID:0000000001724529
1.
CHECK CHARGE WARNING LAMP CIRCUIT CONNECTION
Verify generator connector F2 terminal 2 is clean and tight.
Is the connection secure?
YES
>> GO TO 2
NO
>> Repair the connection. Confirm repair by performing complete Starting/Charging system test.
Refer to Technical Service Bulletin.
2.
CHECK CHARGE WARNING LAMP CIRCUIT
1.
Disconnect generator connector F2.
2.
Apply ground to generator harness connector F2 terminal 2 with
the ignition switch in the ON position.
Does the charge lamp illuminate?
YES
>> Check generator function. Refer to
NO
>> GO TO 3
3.
CHECK HARNESS CONTINUITY
1.
Turn ignition switch OFF.
2.
Disconnect the generator connector F2 and combination meter
connector M24.
3.
Check continuity between generator harness connector F2 (A)
terminal 2 and combination meter harness connector M24 (B)
terminal 38.
4.
Check continuity between generator harness connector F2 ter-
minal 2 and ground.
Are the continuity results as specified?
YES
>> Replace the combination meter. Refer to
XX-XX, "*****"
.
NO
>> Repair the harness or connector.
