BATTERY/CHARGING SYSTEM
CHARGING SYSTEM INSPECTION
CURRENT LEAKAGE TEST
Remove the main seat (page 2-11).
Turn the ignition switch OFF.
Remove the terminal bolt and disconnect the negative
(–) cable [1] from the battery.
Connect the ammeter (+) probe to the negative (–)
cable and ammeter (–) probe to the battery negative (–)
terminal [2].
With the ignition switch turned 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: 2.8 mA max.
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
• Be 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 off the
ignition switch. 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 main seat (page 2-11).
