Charging Voltage Inspection
Caution
y
Before conducting the inspection, be sure
that the battery is fully charged. If
undercharged, the current changes
dramatically.
y
Use a fully charged battery having a voltage
larger than 13.0 V
y
While starting the engine, the starter motor
draws large amount of current from the
battery.
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
When the probe is reversibly connected, use
an ammeter having an indication that shows
both positive and negative direction current.
The measurement would be at zero, if the
ammeter is one direction only.
Caution
y
Do not use short-circuit cable.
y
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 starter to start the
engine.
y
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.
Connect a tachometer.
Turn on the headlight to high beam and start the
engine.
Accelerate the engine to the specified revolution
per minute and measure the charging voltage.
Specified Charging Current: 1.2 A / 5000 rpm
Control Charging Voltage: 14.0~15.0 V / 5000
rpm
Caution
To replace the old battery, use a new battery
with the same current and voltage.
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.
-
Bulbs used exceed their rate and
consume too much power.
-
The replacement battery is aged and
does not have enough capacity.
(2) The charging voltage is normal, but the
current is not.
-
The replacement battery is aged and
does not have enough capacity.
-
Battery used do not have enough
electricity or is over charged.
-
The fuse of the ammeter is blown.
-
The ammeter is improperly connected.
(3) The charging current is normal, but the
voltage is not.
-
The fuse of the voltmeter is blown.
