L TERMINAL CIRCUIT (OPEN)

Description

INFOID:0000000009269531

The “L” terminal circuit controls the charge warning lamp. The charge warning lamp turns ON when the igni-

tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,

the charge warning lamp turns OFF. If the charge warning lamp illuminates with the engine running, a malfunc-

tion is indicated.

Diagnosis Procedure

INFOID:0000000009269532

Regarding Wiring Diagram information. Refer to 

CHG-8, "Wiring Diagram"

.

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 Charging system test

using EXP-800 NI or GR8-1200 NI (if available). Refer to applicable Instruction Manual for proper

testing procedures.

2.

CHECK “L” TERMINAL CIRCUIT (OPEN)

1. Disconnect the generator connector.

2. Apply ground to generator 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-13, "Work Flow (With EXP-800 NI or GR8-1200 NI)"

 or

CHG-16, "Work Flow (Without EXP-800 NI or GR8-1200 NI)"

.

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 generator harness connector and combination meter harness connector.

Description

INFOID:0000000009269533

The terminal “L” circuit controls the charge warning lamp. The charge warning lamp turns ON when the igni-

tion switch is set to ON or START. When the generator is providing sufficient voltage with the engine running,

the charge warning lamp turns off. If the charge warning lamp illuminates with the engine running, a malfunc-

tion is indicated.

Diagnosis Procedure

INFOID:0000000009269534

Regarding Wiring Diagram information, refer to 

CHG-8, "Wiring Diagram"

.

1.

CHECK “L” TERMINAL CIRCUIT (SHORT)

1. Turn ignition switch OFF. 

2. Disconnect generator connector.

3. Turn ignition switch ON.
Does charge warning lamp illuminate?

YES

>> GO TO 2.

NO

>> Refer to 

CHG-13, "Work Flow (With EXP-800 NI or GR8-1200 NI)"

 or 

CHG-16, "Work Flow (With-

out EXP-800 NI or GR8-1200 NI)"

. 

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

1. Turn ignition switch OFF.

2. Disconnect the battery cable from the negative terminal. 

3. Disconnect combination meter connector.

4. Check continuity between the combination meter harness connector and ground.

Is the inspection result normal?

YES

>> Replace the combination meter. Refer to 

MWI-104, "Removal and Installation"

 (Type B) or 

MWI-

S TERMINAL CIRCUIT

S TERMINAL CIRCUIT

Description

INFOID:0000000009269535

The output voltage of the generator is controlled by the IC regulator at terminal “S” detecting the input voltage

from battery. 

The “S” terminal circuit detects the battery voltage to adjust the generator output voltage with the IC voltage

regulator.

Diagnosis Procedure

INFOID:0000000009269536

Regarding Wiring Diagram information. Refer to 

CHG-8, "Wiring Diagram"

.

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 Charging system test

using EXP-800 NI or GR8-1200 NI (if available). Refer to the applicable Instruction Manual for

proper testing procedures.

CHECK “S” TERMINAL CIRCUIT

Check voltage between generator harness connector and ground.

Is the inspection result normal?

YES

>> Refer to 

CHG-13, "Work Flow (With EXP-800 NI or GR8-1200 NI)"

 or
