BATTERY/CHARGING SYSTEM

CHARGING SYSTEM INSPECTION
CURRENT LEAKAGE TEST
Remove the left side cover (page 2-5).
Turn the ignition switch to “OFF,” and disconnect
the negative (–) cable from the battery.
Connect the ammeter (+) probe to the negative (–)
cable and the ammeter (–) probe to the battery (–)
terminal.
With the ignition switch turned to “OFF,” check for
current leakage.
• When measuring current using a tester, set it to a
high range, and then bring the range down to an
appropriate level. Current flow higher than the
range selected may blow the fuse in the tester.
• While measuring current, do not turn the ignition
switch to “ON.” A sudden surge of current may
blow the fuse in the tester.
If current leakage exceeds the specified value, a
shorted circuit is the probable cause.
Locate the short by disconnecting connections one
by one and measuring the current.
CHARGING VOLTAGE INSPECTION
• Make sure the battery is in good condition before
performing this test.
Remove the left side cover (page 2-5).
Start the engine and warm it up to the operating
temperature; then stop the engine.
Connect the multimeter between the positive and
negative terminals of the battery.
• To prevent a short, make absolutely certain
which are the positive and negative terminals or
cable.
With the headlight on high beam, restart the engine.
Measure the voltage on the multimeter when the
engine runs at 2,000 rpm.
SPECIFIED CURRENT LEAKAGE: 5 mA maximum
Do not disconnect
the battery or any
cable in the
charging system
without first switch-
ing off the ignition
switch. Failure to
follow this precau-
tion can damage
the tester or electri-
cal components.
STANDARD:
Measured battery voltage (page 17-6) < Mea-
sured charging voltage (page 17-9) < 15.5 V
