Work Flow (With EXP-800 NI or GR8-1200 NI)
CHARGING SYSTEM DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
To test the charging system, use the following special service tools:
NOTE: Refer to the applicable Instruction Manual for proper charging system diagnosis procedures.
OVERALL SEQUENCE
DETAILED FLOW
NOTE: To ensure a complete and thorough diagnosis, the battery, stater and generator test segments must be done as a set from start to finish.
1.PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to CHG-16, "Diagnosis Procedure".
>> GO TO 2.
2.DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
Perform the charging system test using Multitasking battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer EXP-800 NI. Refer to the applicable Instruction Manual for proper testing procedures.
Test result NO PROBLEMS>>Charging system is normal and will also show “DIODE RIPPLE” test result.
NO VOLTAGE>>GO TO 3.
LOW VOLTAGE>>GO TO 10.
HIGH VOLTAGE>>Replace generator. Refer to CHG-20, "Removal and Installation".
EXCESSIVE RIPPLE, OPEN PHASE, OPEN DIODE or SHORTED DIODE>>Replace the generator. Refer to CHG-20, "Removal and Installation". Perform “DIODE RIPPLE” test again using Multitasking battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer EXP-800 NI to confirm repair.
3.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
Turn the ignition switch ON.
Does the charge warning lamp illuminate? YES >> GO TO 4.
NO >> Replace generator. Refer to CHG-20, "Removal and Installation".
4.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle.
Does the charge warning lamp turn OFF? YES >> GO TO 5.
NO >> GO TO 6.
5.INSPECTION WITH CHARGE WARNING LAMP (ENGINE AT 3,000 RPM)
Increase and maintain the engine speed at 3,000 rpm.
Does the charge warning lamp remain off? YES >> GO TO 7.
NO >> GO TO 6.
6.INSPECTION OF GENERATOR PULLEY
Check generator pulley. Refer to EM-13, "Checking".
Is generator pulley normal? YES >> Replace generator. Refer to CHG-20, "Removal and Installation".
NO >> Repair as needed.
7.“B” TERMINAL CIRCUIT INSPECTION
Check “B” terminal circuit. Refer to CHG-18, "Diagnosis Procedure".
Is “B” terminal circuit normal? YES >> Replace generator. Refer to CHG-20, "Removal and Installation".
NO >> Repair as needed.
8.“B” TERMINAL CIRCUIT INSPECTION
Check “B” terminal circuit. Refer to CHG-18, "Diagnosis Procedure".
Is “B” terminal circuit normal? YES >> GO TO 9.
NO >> Repair as needed.
9.INSPECTION OF GENERATOR PULLEY
Check generator pulley. Refer to CHG-20, "Removal and Installation".
Is generator pulley normal? YES >> Replace generator. Refer to CHG-20, "Removal and Installation".
NO >> Repair as needed.
Work Flow (Without EXP-800 NI or GR8-1200 NI)
OVERALL SEQUENCE
Before performing a generator test, make sure that the battery is fully charged. A 30-volt voltmeter and suitable test probes are necessary for the test.
DETAILED FLOW
1.PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to CHG-16, "Diagnosis Procedure".
>> GO TO 2.
2.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS TURNED ON)
When ignition switch is turned ON.
Does the charge warning lamp illuminate? YES >> GO TO 3.
NO >> Replace generator. Refer to CHG-20, "Removal and Installation".
3.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle Does the charge warning lamp turn OFF? YES >> GO TO 4.
NO >> GO TO 5.
4.INSPECTION WITH CHARGE WARNING LAMP (ENGINE AT 2,500 RPM)
Increase and maintain the engine speed at 2,500 rpm.
Does the charge warning lamp illuminate? YES >> GO TO 5.
NO >> Inspection End.
5.MEASURE “B” TERMINAL VOLTAGE
Start engine. With engine running at 2,500 rpm, measure “B” terminal voltage.
What voltage does the measurement result show? Less than 13.0 V>>GO TO 6.
More than 16.0 V>>Replace generator. Refer to CHG-20, "Removal and Installation".
6.“B” TERMINAL CIRCUIT INSPECTION
Check “B” terminal circuit. Refer to CHG-18, "Diagnosis Procedure".
Is the inspection result normal? YES >> Replace generator. Refer to CHG-20, "Removal and Installation".
NO >> Repair as needed.
