TROUBLESHOOTING
BATIERY IS DAMAGED OR WEAK
1.. BATIERYTEST
Remove the battery (page 18-6).
Check the battery condition using the recommended battery tester.
RECOMMENDED BATIERYTESTER:BM·210.AH (U.S.A. only), BM·210 or BATIERY MATE (MTP08·
0192, U.S.A. only) or equivalent
Is the battery good condition?
NO - Faulty battery.
YES
- GO TO STEP 2.
2. CURRENT LEAKAGE TEST
Install the battery (page 18-6).
Check the battery current leakage test (Leak test; page 18-7).
Is the current leakage below 1 mAl
YES - GO TO STEP 4.
NO - GO TO STEP
3.
3. CURRENT LEAKAGE TEST WITHOUT REGURETOR/RECTIRRE CONNECTOR
Disconnect the regulator/rectifier connector and recheck the battery current leakage.
Is the current leakage below 1 mAl
YES - Faulty regulator/rectifier.
NO - . Shorted wire harness
• Faulty ignition switch
4. ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil (page 18-8).
Is the alternator charging coil resistance within 0.1- 1.0
n
(20OCI68°Fj?
NO - Faulty charging coil.
YES - GO TO STEP 5..
5. CHA.89ING VOLTAGE INSPECTION
Measure and '~ecord the battery voltage using a digital multimeter (page 18-6).

6. REGlfLATOR/RECTIRER SYSTEM INSPEC"nON
Check the voltage and resistance at the regulator/rectifier connectors (page 18-8).
Are the resuhs of checked vohage and resistance correct?
YES - Faulty regulator/rectifier.
NO _. Open circuit in related wire
• Loose or poor contacts of related terminal
• Shorted wire harness
