CHARGING SYSTEM INSPECTION

LEAK TEST

Trun off the ignition switch, and disconnect the ground
(-) cable from the battery.
Connect an ampere meter between negative (-)
terminal and ground cable.
With the ignition switch off, measure the leakage current.
LEAK CURRENT : Not to exceed 1mA
TOOL : DIGITAL TESTER
NOTE
When measuring current using a tester, set it to a
large range, and then bring it down the range to an
appropriate level.
Current flow larger than the range selected may blow
out the fuse in the tester.
While measuring current, do not turn the ignition on.
A sudden surge of current may blow out the fuse in
the tester.

CHARGING VOLTAGE INSPECTION

NOTE
Be sure that the battery is fully charged before
performing this test. The amount of current flow may
change abruptly if not sufficiently charged. Use a
battery whose voltage between its terminals is
13.0~13.2V
When the engine is started using the starter motor, a
large amount of current may flow from the battery
temporarily. Use the kick starter to start the engine.
After warming up the engine, replace the battery with a
fully charged battery.
Connect a tester between the battery terminals.
Connect an ampere meter between the terminals of the
main fuse.
NOTE
If the probes are connected in reverse order, the
registered current flow direction when charging and
discharging the battery will be reversed as well.
Connect a RPM tester to the high-tension cord.
Start the engine.
Gradually increase the engine speed and measure the
charging voltage and charging current.
CHARGING CURRENT : 2.5~3.5A / 3,000rpm
CONTROL VOLTAGE : 14.5 0.5V / 5,000rpm
TOOLS : RPM TESTER
DIGITAL TESTER
Install in the reverse order of removal.
