Output Test

▶

Disconnect the cable connected to the B

terminal on the alternator. Connect one

end of the ammeter to the B terminal and

the other end to the cable connected to

the B terminal.

Measure the maximum output value.

(Maintain the engine speed between

2,500 and 3,000 rpm.)

(Turn the headlamp and all the electrical

switches on.)

1.

2.

Pass: If the measured current

is 45 A or higher.

Fail: If the measured current is

less than 45 A.

Check the current of the B

terminal.

-

-

-

Move the gear selector lever to the neutral

position.

Maintain the engine speed at 2,500 rpm

with the vehicle unloaded.

(Turn all the electrical switches off.)

1.

2.

Open circuit: If the measured

current is 5 A or higher.

-

Disconnect the negative cable from the

battery.

Remove the B terminal and turn off the

ignition switch.

Measure the resistance between the L

and F terminals with an ohmmeter.

1.

2.

3.

Pass: If the measured

resistance is between 3 and
6Ω.

Faulty rotor coil or slip ring: If

the measured resistance is
less than 3Ω or greater than
6Ω.

-

-

Connect the B terminal wiring.

Measure the voltage with the engine

running.

1.

2.

Specification: 12.5V to 14.5V

Faulty IC regulator or field

coil: If the measured voltage

is 14.5V or higher.

-

-

Disconnect the negative cable from the battery.

Connect the negative cable again after connecting the ammeter.

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
(⑥): Overcharged by an alternator
