TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1. BATTERY TEST
Remove the battery (page 17-5).
Check the battery condition using the recommended battery tester.
Is the battery in good condition?
YES – GO TO STEP 2.
No – Faulty battery
2. CURRENT LEAKAGE TEST
Install the battery (page 17-5).
Check the battery current leakage test (Leak test; page 17-7).
Is the current leakage below 2.0mA?
YES – GO TO STEP 4.
NO – GO TO STEP 3.
3. CURRENT LEAKAGE TEST WITHOUT REGULATOR/RECTIFIER CONNECTOR
Disconnect the regulator/rectifier connector and recheck the battery current leakage.
Is the current leakage below 2.0mA?
YES – Faulty regulator/rectifier
NO – • Shorted wire harness
• Faulty ignition switch
4. ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil (page 17-8).
Is the alternator charging coil resistance within 0.1 – 1.0
Ω
(20
°
C/68
°
F)?
YES – GO TO STEP 5.
No – Faulty charging coil
5. CHARGING VOLTAGE INSPECTION
Measure and record the battery voltage using a digital multimeter (page 17-7).
Start the engine.
Measure the charging voltage (page 17-7).
Compare the measurement to result of the following calculation.
Is the measured charging voltage within the standard voltage?
YES – Faulty battery
NO – GO TO STEP 6.
6. REGULATOR/RECTIFIER SYSTEM INSPECTION
Check the voltage and resistance at the regulator/rectifier connector (page 17-8).
Are the results of checked voltage and resistance correct?
YES – Faulty regulator/rectifier
NO – • Open circuit in related wire
• Loose or poor contacts of related terminal
• Shorted wire harness
RECOMMENDED BATTERY TESTER:
BM-210 or BATTERY MATE or equivalent
STANDARD: Measured BV < Measured CV < 15.5 V
· BV = Battery Voltage (page 17-7)
· CV = Charging Voltage
