B TERMINAL CIRCUIT
DescriptionINFOID:0000000012431251
“B” terminal circuit supplies power to charge the batte
ry and to operate the vehicles electrical system.
Diagnosis ProcedureINFOID:0000000012431252
Regarding Wiring Diagram information. Refer to CHG-9, "Wiring Diagram".
1.CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “B” terminal is clean and tight.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair terminal “B” connection. Confirm repair by performing complete Charging system test using the EXP-800 NI or GR8-1200 NI (if availabl e). Refer to applicable Instruction Manual for
proper testing procedures.
2.CHECK “B” TERMINAL CIRCUIT
Check voltage between generator “B” terminal and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Check harness for open between generator and fusible link.
3.CHECK “B” TERMINAL CONNECT ION (VOLTAGE DROP TEST)
1. Start engine, then engine running at idle and warm.
2. Check voltage between battery positive te rminal and generator connector “B” terminal.
Is the inspection result normal?
YES >> “B” terminal circuit is normal. Refer to CHG-14, "Work Flow (With EXP-800 NI or GR8-1200 NI)"
or CHG-17, "Work Flow (Without EXP-800 NI or GR8-1200 NI)".
NO >> Check harness between battery and generator for continuity.

L TERMINAL CIRCUIT (OPEN)
DescriptionINFOID:0000000012431253
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 warn ing lamp illuminates with the engine running, a malfunc-
tion is indicated.
Diagnosis ProcedureINFOID:0000000012431254
Regarding Wiring Diagram information. Refer to CHG-9, "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 repa ir 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” TERMIN AL 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)" or
CHG-17, "
Work Flow (Without EXP-800 NI or GR8-1200 NI)".
NO >> GO TO 3.
3.CHECK HARNESS CONTI NUITY (OPEN CIRCUIT)
1. Disconnect the battery cable from the negative terminal.
2. Disconnect the combination meter connector.
3. Check continuity between generator harness c onnector 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.
