L TERMINAL CIRCUIT (OPEN)
L TERMINAL CIRCUIT (OPEN)
Description
INFOID:0000000009755967
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:0000000009755968
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 Instruction 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-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
CHG-17, "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 POWER SUPPLY CIRCUIT
1. Connect the battery cable to the negative terminal.
2. Check voltage between combination meter harness connector and ground.

Description
INFOID:0000000009755971
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:0000000009755972
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 Instruction 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-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
out EXP-800 NI or GR8-1200 NI)"
