TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1. BATTERY TEST
Remove the battery (page 21-6).
Check the battery condition using the recommended battery tester.
RECOMMENDED BATTERY TESTER: BM-210 or BATTERY MATE or equivalent
Is the battery good condition?
YES
NO
2. CURRENT LEAKAGE TEST
Install the battery (page 21-6).
Check the battery current leakage test (page 21-7).
Is the current leakage below 1.2 mA?
YES
NO
3. CHARGING VOLTAGE INSPECTION
Measure and record the battery voltage using a digital multimeter (page 21-6).
Start the engine.
Measure the charging voltage (page 21-7).
Compare the measurement to result of the following calculation.
STANDARD:
Measured BV < Measured CV < 15.5 V
• BV = Battery Voltage
• CV = Charging Voltage
Is the measured charging voltage within the standard voltage?
YES
NO
4. REGULATOR/RECTIFIER SYSTEM INSPECTION
Check the voltage and resistance at the regulator/rectifier connector (page 21-8).
Are the results of checked voltage and resistance correct?
YES
NO
5. ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil (page 21-9).
Is the alternator charging coil resistance within 0.1 – 0.5 Ω (20°C/68°F)?
YES
NO
6. CURRENT LEAKAGE TEST WITHOUT REGULATOR/RECTIFIER CONNECTOR
Disconnect the regulator/rectifier 2P (Black) connector and recheck the battery current leakage.
Is the current leakage below 1.2 mA?
YES
NO
