BATTERY /CHARGING SYSTEM
TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1
.
BATTERY TEST
Remove the battery ( page 21
-
5 )
.
Check the battery condition using the recommended battery
tester
,
RECOMMENDED BATTERY TESTER : Micro 404 XL ( U . S . A
.
only ) , BM
-
210 or equivalent
Is the battery good condition ?
YES
-
GO TO STEP 2
.
NO
-
Faulty battery
2
. CURRENT LEAKAGE TEST
Install the battery ( page 21
-
5 )
.
Check the battery current leakage test ( page 21
-
6 )
.
Is the current leakage below 0.2 mA ?
YES
-
GO TO STEP 3
.
NO
-
GO TO STEP 6
.
3 . CHARGING VOLTAGE INSPECTION
Measure and record the battery voltage using a digital multimeter ( page 21
-
5 ) .
.
1
Start the engine .
Measure the charging voltage ( page 21
-
6 ) .
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
-
Faulty battery
NO
-
GO TO STEP 4
.
4 . REGULATOR/ RECTIFIER SYSTEM INSPECTION
Check
the voltage and resistance at the regulator / rectifier connector ( page 21
-
7 )
.
Are the
results of checked voltage and resistance correct ?
YES
-
GO TO STEP 5
,
NO
-
• Open circuit in related wire
• Loose or
poor contacts of related terminal
•
Shorted wire harness
5
.
ALTERNATOR CHARGING COIL INSPECTION
Check the alternator charging coil ( page 21
-
8 )
.
Is the alternator charging coil resistance within 0.1
-
0.5 O ( 20 ° C / 68 ° F ) ?
YES
-
Faulty regulator / rectifier
NO
-
Faulty charging coil
6
.
CURRENT LEAKAGE TEST WITHOUT REGULATOR /RECTIFIER CONNECTOR
Disconnect the regulator /rectifier 3 P ( Black ) connector and recheck the battery current leakage .
Is the current leakage below 0.2 mA ?
YES
-
Faulty regulator /rectifier
NO
-
• Shorted wire harness
• Faulty ignition switch
