Using battery tester ▶
PASS (11.0 V or more): Explain to the customer that the battery is reusable.
Need to be charged (9.0 to 11.0 V): Charge the battery with a charger and reinstall it. Explain it to the
customer.
Need to be replaced (9.0 V or more): The battery should be replaced due to overdischarging. -
-
-
How to use battery tester ▶
Determine battery capacity by fixing current
(load capacity) and time and varying voltage.
Determine battery capacity based on the
amount of voltage drop when discharging a
fixed load capacity (120 A) for 5 seconds.
Connect the tester to the battery and read the
display while applying a load for 5 seconds. -

-
Red area (①): overdischarge or faulty
battery
Yellow area (②): Need to be charged
(using a vehicle alternator and a battery
charger)
Green area (③): Normal
Red area on the left-hand side of OK (④):
Impossible to charge with an alternator
Green area with OK (⑤): Normally charged
Red area on the right-hand side of OK

Battery
It converts the chemical energy to the
electrical energy and supplies power to the
corresponding electric units when starting the
engine.
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.
Body ground
B+ wiringAlternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.

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.

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.

Specified valueover 12V
Specified value11.5 ~ 15.5V
Make sure to set up the tester while keeping
its polarity.
