1) Alternator Output Test

Item
1. 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

2. 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. Move the gear selector lever to the
neutral position.

resistance
3. Measure the resistance between the L
and F terminals with an ohmmeter.
1. Connect the B terminal wiring.

- Disconnect the negative battery cable.
- Connect the negative cable again after connecting the ammeter.
How to check DTC set value / Action
- 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.
- Open circuit: If the measured
current is 5 A or higher.
- 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.
- Specification: 12.5 V to 14.5 V
- Faulty IC regulator or field coil: If
the measured voltage is 14.5 V
or higher.
