B TERMINAL CIRCUIT

Description

INFOID:0000000001724526

The terminal “1” (B) circuit supplies power to charge the battery and operate the vehicles electrical system.

Diagnosis Procedure

INFOID:0000000001724527

1.

CHECK TERMINAL “1” CONNECTION

1.

Turn ignition switch OFF.

2.

Verify terminal “1” is clean and tight.

Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair terminal “1” connection. Confirm repair by performing complete Starting/Charging system

test. Refer to Technical Service Bulletin.

2.

CHECK TERMINAL “1” CIRCUIT

Check voltage between generator connector F2 terminal 1 and
ground.

Is voltage reading as specified?

YES

>> GO TO 3.

NO

>> Check harness for open between generator and fusible

link.

3.

CHECK TERMINAL “1” CONNECTION (VOLTAGE DROP TEST)

1.

Start engine, then engine running at idle and warm.

2.

Check voltage between battery positive terminal and generator
connector F2 terminal 1.

Is the voltage reading as specified?

YES

>> Terminal “1” circuit is normal. Refer to 

CHG-33, "Work

Flow"

.

NO

>> Check harness between battery and generator for high resistance.

L TERMINAL CIRCUIT

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 

CHG-33, "Work

Flow"

.

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.
