To
prevent
a
short,
make absolutely
certain which are
the positive
and
negative terminals
or
cables.
CHARGING
NOTE:
INSPECTION
• Make sure the battery
is
in
good condition before
performing this test.
•
Do
not disconnect the battery or any cable
in
the
charging system without first switching the ignition
switch
to
OFF. Failure to follow this precaution can
damage the tester or electrical components.
Warm
up
the engine
to
normal operating temperature.
Stop the engine.
Remove the battery maintenance
lid
(page 20-7) and
connect the multimeter
as
shown.
Connect a tachometer.
With the headlight
on
high beam, restart the engine.
Measure the voltage
on
the multimeter when the engine
runs at 5,000
rpm.
STANDARD:
Measured BV
<
Measured CV
<
15.5 V
• BV
=
Battery Voltage (page 20-8)
•
CV=
Charging Voltage
CHARGING LINE INSPECTION
Disconnect the ECM
5P connector (page
4-49).
Turn the ignition switch
ON
and engine stop switch
"0".
Measure the voltage between the ECM
5P
connector
[1] of the wire harness side and ground.
CONNECTION: Red/yellow(+) - ground
(-)
STANDARD: Battery voltage
If there
is
battery voltage, charging line
is
normal.
If there
is
no
voltage, inspect the following:
- Loose or poor contacts
of
related terminal
- Open circuit
in
the Red/black wire between the main
relay
and
starter/charging relay
Open circuit
in
the Red/yellow wire between the
starter/charging relay and ECM
