TROUBLESHOOTING
Battery is damaged or weak
1.
BatteryTest
Remove the battery
(page
19-6).
Check
the battery condition using the recommended battery tester.
RECOMMENDED
BATTERY TESTER: Micro 404XL (U.S.A. only)
ls
the
battery in good
condition?
YES
- GOTOSTEP2.
NO -
Faulty battery
2.
Current Leakage
Test
lnstallthe battery (page 19-6).
Check
the battery current leakage using a digital multimeter (page
'19-7).
ls
the
cunent
leakage below
1.0
mA?
YES
-
GO
TO
STEP 4.
NO -
GO TO STEP
3.
3.
Current Leakage Test
with Regulator/rectifier Connector Disconnected
Disconnect the
regulator/rectifier 3P (Black) connector (page
19-8).
Recheck
the
battery current leakage.
ls
the
current
leakage below
1.0
mA?
YES
-
Faulty regulator/rectifier
NO - .
Shorted wire harness
.
Faulty ignition switch
4.
Gharging Voltage lnspection
Measure
and
record
the
battery
voltage using a digital multimeter
(page
19-6).
Start the engine.
Measure
the
charging
voltage (page
19-7).
Compare the measurements to
the
results of the
following
calculation.
STANDARD:
Measured BV
<
Measured
GV
< 15.5
V
.
BV =
Battery Voltage
.
CV =
Charging Voltage
Do
the
battery and charging voltages satisfy the calculation?
YES
-
Faulty battery
NO -
GOTOSTEP5.
5.
Regulator/rectifier
Wire Harness
lnspection
Check the regulator/rectifier
wire
harness
(page
19-8).
Are
the
results
of
checked
voltage and continuity correct?
YES
-
GO
TO
STEP 6.
NO - .
Open circuit in related wire
.
Loose
or poor contacts of
related terminal
.
Shorted
wire harness
6.
Phase
Controlled Generating Circuit lnspection
Check the
phase controlled generating circuit with
the MCS
(page
19-8).
ls
the
circuit normal?
YES
-
Faulty regulator/rectifier
NO - .
Repair the connection.
.
Replace the faulty component.
