Measuring the voltage drop between lines
Measure the voltage drop between alternator B+ and battery B+. -
Specified valuebelow 0.3V
If the value is out of the specified value, check the terminal and clamp for looseness.
Checking the charge warning lamp
Check if the charge warning lamp goes out.
If the charge warning lamp does not go off, inspect the electric circuit.
Start the engine and check if the charge warning lamp keeps off. 1.

4. INSPECTION - CHARGING CURRENT
Perform the basic inspection. -
Setting up the testers
Preparation
Set up the ammeter and voltmeter as
shown in the figure. 1.
Make sure to set up the tester while keeping
its polarity.

0000-00
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.

5. INSPECTION - REGULATING VOLTAGE
Perform the basic inspection. -
Setting up the testers
Preparation
Set up the ammeter and voltmeter as shown
in the figure. 1.
Inspection
Turn the ignition ON and measure the voltage on the voltmeter. 1.
Start the engine and turn all electric devices OFF.
Increase the engine speed to 2,700 rpm and maintain the speed. Measure the voltage when the
output current from alternator decrease below 30A. 2.
3.
Specified valueover 12V
Specified value11.5 ~ 15.5V
Make sure to set up the tester while keeping
its polarity.

0000-00
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.
2.
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.

0000-00
Specified
valueover 11V: Normal
9 ~ 11V: Charging required
below: 9V: Over discharged,
battery replacement required
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).

Turn the ignition ON (Engine stopped)
Open or short circuit of L terminal wiring, open or short internal circuit of alternator (fixed control of
13.8V)
Open or short circuit of F terminal wiring, no feedback output signal 1.
