L TERMINAL CIRCUIT (OPEN)
L TERMINAL CIRCUIT (OPEN)
Description
INFOID:0000000009465974
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:0000000009465975
Regarding Wiring Diagram information. Refer to
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-2, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
CHG-5, "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.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace the harness or connectors.
4.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check continuity between combination meter harness connector and fuse block (J/B).

Description
INFOID:0000000009465978
The output voltage of the generator is controlled by the IC voltage regulator at the “S” terminal detecting the
input voltage. Terminal “S” circuit detects the battery voltage to adjust the generator output voltage with the IC
voltage regulator.
Diagnosis Procedure
INFOID:0000000009465979
Regarding Wiring Diagram information, refer to
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.
2.
CHECK “S” TERMINAL CIRCUIT
Check voltage between generator harness connector and ground.
Is the inspection result normal?
YES
>> Refer to
CHG-2, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
.
NO
>> Check harness for open between generator and fuse.
