Note
Connect the positive terminal of the
multimeter with the negative terminal
of the battery.
Check whether there is a short-circuit in the main
switch or in the main wire in the case of any
abnormality.
1.4.2 Charging check
Use a multimeter to check the charging status of the
battery when it is being fully charged.
Install the fully charged battery after the engine
warms up. Connect a voltmeter between terminals.
Remove the main fuse and connect an ammeter
between the terminals.
Start the engine and increase its speed gradually to
measure the limiting voltage and current.
Limiting voltage/speed: 14-15V @ 5,000 rpm
Check the voltage regulator if the limiting voltage is not within its required
range. Check the limiting voltage of the lighting system.
* Note
Set the multimeter to the AC voltage
position.
Limiting voltage: 13.1±0.5V @ 5,000 rpm
Check the voltage/current regulator if the limiting voltage is not within its
required range.
1.5 Voltage/current regulator
1.5.1 Main wiring check
Remove 4p plug of the voltage/current
regulator. Check conductivity between main
wiring terminals.

1.5.2 Voltage-current regulator check
1.
Select “diode” in the multimeter;
2. The black probe connects the red terminal of the stabilizer, and the red probe respectively
connects white terminals of the stabilizer (white1, white2 and white3). Pointers indicate values.
If not, the stabilizer is damaged and needs replacement.
