Charging Voltage/Current
Inspection
Caution
After the engine is warmed up, replace
original battery with a fully charged battery.
Connect a digital voltmeter to the battery
terminals.
Connect an ammeter between both ends of
the main fuse.
Caution
Caution
Connect a tachometer.
Turn on the headlight to high beam and start the
engine.
Accelerate the engine gradually to the specified
revolution per minute and measure the charging
voltage/current.
Specified Charging Current:
(headlight OFF) 0.6 A or more/2500rpm
1.2 A or more / 6000 rpm
(headlight ON)
0.4 A or more/2500rpm
1.0 A or more / 6000 rpm
Control Charging Voltage:
14.0+/0.5 V / 2000 rpm
Caution
The following problems are related to the
charging system, follow the instructions provided
in the checking list to correct it if any one of the
problems takes place.
(1) The charging voltage can not exceed the
voltage between two battery terminals and
the charging current is in the discharging
direction.
(2) The charging voltage and current are too
much higher than the standard values.
The following problems are not related to the
charging system; correct it if any by following
steps indicate in the checking list.
(1) The standard charging voltage and current
can only reach when the revolution of the
engine exceeds the specified rpm.
z
Bulbs used exceed their rate and
consume too much power.
z
The replacement battery is aged and
does not have enough capacity.
(2) The charging voltage is normal, but the
current is not.
z
The replacement battery is aged and
does not have enough capacity.
z
Battery used do not have enough
electricity or is over charged.
z
The fuse of the ammeter is blown.
z
The ammeter is improperly connected.
(3) The charging current is normal, but the
voltage is not.
z
The fuse of the voltmeter is blown.

z
Before conducting the inspection, be sure
that the battery is fully charged. Use a
fully charged battery having a voltage
larger than 13.0 V. If undercharged, the
current changes dramatically.
z
While starting the engine, the starter
motor draws large amount of current from
the battery. Thus, do not start the engine
with battery.
When the probe is reversibly connected, use
a voltmeter having an indication that the
current flows from the positive or the
negative direction and the measurement
should be at zero, ammeter at one direction
only.
z
Do not use short-circuit cable.
z
It is possible to measure the current by
connecting an ammeter between the
battery positive terminal and the cable
position terminal, however, while the
starter motor is activated, the surge
current of the motor draws from the
battery may damage the ammeter. Use
the kick lever to start the engine.
z
The main switch shall be turned to OFF
position during the process of inspection.
Never tamper with the ammeter and the
cable while there is current flowing
through. It may damage the ammeter.
To replace the old battery, use a new battery
with the same current and voltage.
