BATTERY/CHARGING SYSTEM

CHARGING SYSTEM INSPECTION
CURRENT LEAKAGE INSPECTION
Remove the maintenance lid (page 3-4).
Turn the ignition switch "OFF" and disconnect the
negative (–) cable from the battery.
Connect the ammeter (+) probe to the battery (–)
cable and the ammeter (–) probe to the battery (–)
terminal.
With the ignition switch "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 "ON". A sudden surge of current may
blow the fuse in the tester.
If current leakage exceeds the specified value, a
shorted circuit is likely.
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 maintenance lid (page 3-4).
Warm up the engine to normal operating tempera-
ture.
Stop the engine and connect the multimeter as
shown.
Measure and record the battery voltage using a
multimeter.
• To prevent a short, make absolutely certain
which are the positive and negative terminals or
cable.
Restart the engine.
With the headlight on Hi beam, measure the charg-
ing voltage on the multimeter when the engine runs
at 5,000 min
-1
(rpm).
• BV = Battery Voltage
• CV = Charging Voltage
If the voltage is abnormal, checks in the trouble-
shooting flow chart (page 19-5).
SPECIFIED CURRENT LEAKAGE: 1.5 mA max.

TERMINAL
Do not disconnect
the battery or any
cable in the charg-
ing system without
first switching the
ignition switch
"OFF". Failure to do
so can damage the
tester or electrical
components.
