1.4 Charging System

1.4.1 Short circuit test
Disconnect the grounding wire from the battery and use a
voltmeter to connect battery negative lead wire with grounding
wire. Set the switch at OFF position and check if it is shorted.
* Attention
Positive lead wire of multimeter is connected to negative lead
wire of battery.
If abnormality found, check if there is short circuit on ignition switch and main wiring.
1.4.2 Charging state inspection
While inspection, battery shall be fully charged and a multimeter be used for the test.
Warm up the engine and then install fully charged battery onto the
motorcycle.
Connect voltmeter between terminals of the battery.
Remove the main fuse and connect ammeter between the two terminals.
Start engine and slowly raise RPM. Measure limited voltage and current.
Limited voltage/rpm: 14-15V (5.000rpm)
If limited voltage is beyond the specified range, check voltage regulator.
Inspect limited voltage in lighting system.
* Attention
Set multimeter to position of AC voltage
