09-6 Item How to check DTC set value / Action Output current B terminal current Rotor coil resistance L terminal voltage 3. INSPECTION 1) Alternator 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 Faulty rotor coil or slip ring: If the measured resistance is - - 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. - - |
