TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1. BATTERY TEST
Remove the battery (page 15-3).
Check the battery condition using the recommended battery tester.
RECOMMENDED BATTERY TESTER: FBT-50 or equivalent
Is the battery in good condition?
– Faulty battery
NO
– GO TO STEP 2.
YES
2. CURRENT LEAKAGE TEST
Install the battery (page 15-3).
Check the battery current leakage (Leak test; page 15-7).
Is the current leakage below 0.02 mA?
– GO TO STEP 4.
YES
– GO TO STEP 3.
NO
3. CURRENT LEAKAGE TEST WITHOUT REGULATOR/RECTIFIER CONNECTOR
Disconnect the regulator/rectifier 4P connector, and recheck the battery current leakage.
Is the current leakage below 0.02 mA?
– Faulty regulator/rectifier
YES
NO – • Shorted wire harness
• Faulty ignition switch
4. CHARGING VOLTAGE INSPECTION
Start the engine.
Measure the charging voltage (page 15-4).
Compare the measurements to the results of the following calculation.
STANDARD:
Measured BV < Measured CV < 13.5V-14.5V
• BV = Battery Voltage
• CV = Charging Voltage
Is the measured charging voltage within the standard voltage?
– Faulty battery
YES
– GO TO STEP 5.
NO
5. ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil (page 15-8).
Is the alternator charging coil resistance within 0.2 – 1.0 Ω (20°C/68°F)?
– Faulty charging coil
NO
– GO TO STEP 6.
YES
6. REGULATOR/RECTIFIER SYSTEM INSPECTION
Check the voltage and resistance at the regulator/rectifier connector (page 15-9).
Are the results of the checked voltage and resistance correct?
– Faulty regulator/rectifier
YES
– • Open circuit in related wire
NO
• Loose or poor contacts of related terminal
• Shorted wire harness
