Charging System/Battery
Charging System Inspection
Leakage Inspection
Turn the ignition switch OFF. Remove the
negative cable from the battery.
Connect the voltmeters between the negative
cable and battery negative terminal.
Measure the leakage voltage with the main
switch OFF.
• When measuring much voltage than the upper
level of range, the fuse may be burned out.
Ampere meter measure by changing from big
range to small range gradually.
• Don’t turn the main switch ON during
measuring the voltage. When measuring by
the small voltage range as like 1 mA range, the
fuse of tester may be burned out because much
voltage flow.
If the voltage leakage is over 1mA, check the
wire harness to be sure the connection is good
and the wires are not damaged. Recheck the
Charging Output Inspection
• As voltage is changeable according to the
charging state, inspect the charging output in
state of fully charged battery.
• Use the battery which the specific gravity is
over 1,270. <20 (68 )>
• If the engine starts with a starter motor, a lot of
voltage flow for a while because the energy of
battery is spended when starting the engine.
Start the engine and warm it up to operating
temperature. Install a fully charged battery.
Connect the voltmeter (digital tester) between
the positive and negative terminals of the
battery.
Tool: PVA multi tester
Start the engine. Gradually increase the engine
speed and check that the voltage is regulated.
Regulated Voltage: 14.0 0.5V/5,000(rpm)
