BATTERY/CHARGING SYSTEM
TROUBLESHOOTING
BATTERY IS DAMAGED OR WEAK
1.
Battery Test
Remove the battery
(page
19·6).
Check the
battery
condition using the recommended
battery tester.
RECOMMENDED BATTERY
TESTER:
Micro
404Xl (U.S.A
.
only),
BM-2
10
or
equivalent
Is
the battery
in
good condition
?
No
-
Faulty battery
YES
- GO TO STEP 2.
2. Current
Leakage
Test
Install the
battery (page
19-6).
Check
the
battery current leakage test
(l
eak
test:
page
19-7).
Is
the
current
leakage
below
1
rnA?
YES
-
GO
TO
STEP
4,
NO
-
GO
TO STEP
3.
3.
Current
Leakage Test With
Regulator/
Rectifier
Connector
Disconnected
Disconnect
the regulator/rectifier
connector and
recheck the
battery cu
rrent
leakage.
Is the current
leakage
below
7
rnA
?
YES
-
Faulty regulator/rectifier
NO

.
Shorted wire
harness
•
Faulty ignition
switch
4.
Charging Vottage Inspection
Measure
and
record
the battery voltage using
a
digital
multi
meter (page
19-6).
Start the engine.
Measure the
charging voltage
(page
19-71.
Compare
the measurements
to
the results
of
the
f
ollowing calculation.

CV= Charging voltage
Is
the
measured charging voltage within
the
standard
voltage?
YES
- Faulty
battery
NO
-
GO
TO
STEP 5.
5.
Alternator Charging Coil Inspection
Check the alternator charging
coil
(page
19-8).
Is
the alternator charging coil resistance within
D.1 -
1.Dn
(2D

YES
-
GO TO
STEP
6.
NO
-
Faulty
charging coil
6. Regulator/
Rectifier
System Inspection
Check the voltage
and
resistance at the regulator/rectifier
connector
(page
19-8).
Are
the
measurements correct?
YES
- Fau lty regulator/rectifier
NO
•
Open
circuit in related
wire
•
Loose o
