2. INSPECTION

1) Alternator Output Test

Item

How to check

DTC set value / Action

Output 

current

B terminal 

current

Rotor 

coil 

resistance

L 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.
