Inspection
Start the engine and turns on the headlamp, blower and heated wire at their full load. Then, measure
the maximum output current (MSM measurement value) when racing the engine to 2,700 rpm. 1.
Specified value60% of rated current (limit)
Turn the ignition OFF after inspection.
Disconnect the negative cable from the battery and remove the testers (ammeter and
voltmeter). 2.
3.
Characteristic curve (output from alternator)
The output current may not reach the limit value due to various parameters (high temperature or
electric load etc.). Thus, do not perform the inspection with fully charged battery.

Inspection
Measure the current while removing the fuses one by one. If the current drops sharply when a certain
fuse is removed, inspect the affected circuit. 1.
Specified valuebelow 0.05A
6. INSPECTION - DARK CURRENT
Perform the basic inspection. -
Setting up the tester
Preparation
Disconnect the negative cable from the battery.
Set up the ammeter as shown in the figure above. 1.

1) When Using Multi-tester

Specified valuebelow 0.05A
Setting up the tester
Preparation
Disconnect the negative cable from the
battery.
Set up the ammeter and MSM as shown in
the figure above. 1.
2.
2) When Using MSM
Connect the negative cable to the
battery. 3.
Make sure to set up the tester while keeping
its polarity.
Measure the current while removing the fuses
one by one. If the current drops sharply when
a certain fuse is removed, inspect the affected
circuit.

7. INSPECTION - BATTERY
Perform the basic inspection (all electric devices OFF). -
Battery tester
1) Voltage Check (without load)
terminal of battery first, then connect the
clamps in the reverse order). 1.
Read the measurement. 2.

2) Voltage Check (with load)
1Push the load switch to ON (to arrow
direction) direction for less than 5 seconds. 1.
Read the measurement. 2.
Specified
value7 ~ 9V (Red): Over discharged
or faulty
9 ~ 11V (Yellow): Charging
required
11 ~ 13V: Normal
To identify the battery capacity with the
voltage drop (V) value, discharge the fixed
load capacity (120A) for a certain period (5
seconds).

Operation
EEM monitors the electric loads and battery conditions and controls the voltage to improve the fuel
economy and battery charging efficiency.

Engine ECU outputs the information from EBS and regulating control signal (PWM) according to the
Engine ECU controls the magnetic resistance between stator coil and rotor coil by controlling the
current in rotor coil according to PWM duty value.
The alternating voltage induced to stator coil is converted to direct voltage by rectifier. And, EBS

Operation of charge warning lamp
ECU checks the generating voltage from alternator and circuit conditions and sends the warning lamp ON
signal to meter cluster through CAN line.Basic control logic according to the driving conditions
Engine ECU determines the engine loads according to the fuel injection volume and engine speed. It
charges the battery by increasing the generating voltage during deceleration. To improve the fuel
economy by reducing the alternator load during acceleration, engine ECU decreases the generating
voltage and consumes the battery voltage.
