L TERMINAL CIRCUIT (SHORT)
L TERMINAL CIRCUIT (SHORT)
Description
INFOID:0000000009175274
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:0000000009175275
Regarding Wiring Diagram information, refer to
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-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
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-82, "Removal and Installation"
.

S TERMINAL CIRCUIT
Description
INFOID:0000000009175276
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:0000000009175277
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-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or
out EXP-800 NI or GR8-1200 NI)"
.
NO
>> Check harness for open between generator and fuse.
