TRO U BLESHOOTING

BATTERY IS DAMAGED OR WEAK

1 . BATTERY TEST
Remove the battery (page 1 6-6).
Check the battery condition using the recommended battery tester.
RECOMMENDED BATTERY TESTER:
BM-210-AH (U.S.A. only), BM-210 or Battery Mate (MTPOB-0192, U.S.A. only) or equivalent
Is the battery in good condition?
No
YES
2. CURRENT LEAKAGE TEST
Install the battery (page 1 6-6).
Check the battery current leakage test (Leak test; page 1 6-7).
Is the current leakage below 0.1 mA7
YES
NO
3. CURRENT LEAKAGE TEST WITHOUT REGULATOR/RECTIFIER CONNECTION
Disconnect the 6P connector of the ECM and check the battery current leakage test.
Is the current leakage below 0. 1 mA7
NO
YES
4. ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil (page 16-8).
Is the alternator charging coil resistance within 0.05 - 0.5
No
YES
5. CHARGING VOLTAGE INSPECTION
Measure and record the battery voltage using a digital multimeter (page 1 6-6).
Start the engine.
Measure the charging voltage (page 1 6-8).
Compare the measurement to the result of the following calculation.
STANDARD:
Measured battery voltage < Measured charging voltage < 15.5 V
Is the measured charging voltage within the standard voltage?
YES
NO
6. REGULATOR/RECTIFIER SYSTEM INSPECTION
Inspect the regulator/rectifier system on the ECM side (page 1 6-9).
Are the results of checked continuity and resistance correct?
YES
NO
