2. INSPECTION

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 connected to the B
Output
terminal.
current
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.
B terminal
2. Maintain the engine speed at 2,500 rpm
current
with the vehicle unloaded.
(Turn all the electrical switches off.)
1.
Disconnect the negative cable from the
battery.
Rotor
2. Remove the B terminal and turn off the
coil
ignition switch.
resistance
3. Measure the resistance between the L and
F terminals with an ohmmeter.
1. Connect the B terminal wiring.
L terminal
2. Measure the voltage with the engine running.
voltage
- 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.
