resistance

D terminal

voltage

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 6 Ω.

Faulty rotor coil or slip ring: If the

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

-

-

Connect the B terminal wiring.

Measure the voltage with the engine

running.

1.

2.

Specification: 12.5 V to 14.5 V

Faulty IC regulator or field coil: If

the measured voltage is 14.5 V or

higher.

-

-

Disconnect the negative battery cable.

Connect the negative cable again after connecting the ammeter.
