CHARGING SYSTEM INSPECTION
CURRENT LEAKAGE TEST
Remove the maintenance lid (page 21-6).
Turn the ignition switch OFF, disconnect the negative
(–) cable [1] from the battery.
Connect the ammeter (+) probe [2] to the negative (–)
cable and the ammeter (–) probe [3] 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.
SPECIFIED CURRENT LEAKAGE: 1.2 mA maximum
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.
Start the engine and warm it up to the operating
temperature; then stop the engine.
Remove the maintenance lid (page 21-6).
Connect the multimeter between the positive terminal
[1] and negative terminal [2] of the battery.
• To prevent a short, make absolutely certain which
are the positive and negative terminals or cable.
• Do not disconnect the battery or any cable in the
charging system without first switching off the
ignition switch. Failure to follow this precaution can
damage the tester or electrical components.
With the headlight on high beam, restart the engine.
Measure the voltage on the multimeter when the engine
runs at 5,000 min
STANDARD:
Measured BV < Measured CV < 15.5 V
• BV = Battery Voltage (page 21-6)
• CV = Charging Voltage
If the charging voltage reading is out of the
specification, inspect the regulator/rectifier (page 21-8).
