*Note
•Fast charging cannot be used except in contingency
situations.
•Do not measure the voltage until 30 minutes after the
charge.
Charging current ：Standard：0.4A
Fast：4.0A
Charging time ：Standard：10-15h
Fast：30m
Charge completed：open-circuit voltage：12.8V or above
5.4 Charging system
5.4.1Short circuit test
Remove the ground wire off the battery, connect the
voltmeter between the battery negative pole and ground
wire with the switch at OFF and inspect whether there is
short circuit.
*Note
Connect the positive pole of avometer with the negative
pole of battery.
If there is any disorder, please inspect whether the main
switch and main wire are in short circuit condition.
5.4.2 Inspect the charging state
Test with an avometer when the battery is fully charged.
Mount the fully charged battery after the engine warms up.
Connect a voltage meter between the battery terminals.
Connect an amperemeter at the position where two
terminals are disassembled to the main fuse.
Start the engine and measure the clamping voltage and
current when the rotation speed gradually increases.
Clamping voltage/rotation speed ：14-15V （5.000rpm）
If the clamping voltage exceeds the specified value range,
inspect the voltage regulator.
Inspect the clamping voltage of the lighting system.
*Note
Set the avometer at the alternating voltage position.
Clamping voltage ：13.1（+/-）0.5V/5.000rpm
If the clamping voltage exceeds the specified value range,
inspect the voltage and current regulator.
