(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the battery
cables with the ignition key turned to ON or ACC position, several electric units can be damaged
due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted with
soapy water. -

If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a
malfunction in the charge system including the battery. Therefore, carrying out the system check is
needed.

Battery
It converts the chemical energy to the
electrical energy and supplies power to the
corresponding electric units when starting
the engine.Alternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
1. SYSTEM DESCRIPTION
1) Overview
The charge system is designed to supply electrical energy to the vehicle while driving, and supplies a
constant direct current voltage by converting mechanical rotational movement to electrical energy.
The voltage regulator on the back of the alternator controls the generated voltage in all rotating ranges
and adjusts the system voltage according to the electric load and ambient temperature change.

3) Charging
The alternator uses a new regulator which has three diodes. It consists of the delta stator, rectifier bridge,
slip ring and brush.
Charging time according to vehicle conditions and environment
Specification: Charging a fully depleted high-
capacity battery takes twice or more as long as
charging a fully depleted battery for small vehicles.
Temperature: The lower the temperature is, the
longer the time taken to charge the battery. When
connecting the battery charger to the cold battery,
the amount of current the battery can accept
initially is very small. As the battery gets warmer, it
can accept more current.
Charging capacity: Charging a battery with a low-capacity charger takes longer time than charging with
a high-capacity charger.
Charging status: Charging a fully depleted battery takes twice or more as long as charging a half-
depleted battery. Since the electrolyte in a fully depleted battery consists of nearly pure water and
conductor, only a very small amount of current can be accepted by the battery initially. The charging
current increases as the amount of acids in the electrolyte is increased by the charging current.
