Inspection on Charging Voltage
Caution
 Before conducting the inspection, be sure that
the battery is fully charged. If undercharged,
the current changes dramatically.
 Use a fully charged battery having a voltage
larger than 13.0 V to prevent the current
fluctuation.
 While starting the engine, the starter motor
draws large amount of current from the battery.
After the engine is warmed up, replace the original
battery with a fully charged one.
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 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.
Caution
 Do not use any short-circuit cable.
 It is possible to measure the current by
connecting an ammeter between the battery
positive terminal and the cable positive
terminal; however, while the starter motor is
activated, the surge current draws from the
battery may damage the ammeter. Use the kick
starter to start the engine to prevent this
happen.
 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 / 6000 rpm
Control Charging Voltage:
14.5 V/1650 rpm
Caution
When it comes to replacement, make sure
that the current and voltage of the new battery
are the same as the old one.
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
occurs.
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 systems; correct it if any by following
steps indicated in the checking list.
(1) The standard charging voltage and current
can only reach when the revolution of the
engine exceeds the specified rpm.
- Light bulbs used exceed their rate and
consume too much power.
- The replaced battery is aged and does not
have enough capacity.
(2) The charging voltage is normal, while the
current is not.
- The replaced battery is aged and does not
have enough capacity.
- Battery used does 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.
