Output Current Test: Result
- The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good condition, remove the alternator from the vehicle and test it.
Limit value : 60% of the voltage rate
NOTE:- The output current value changes with the electrical load and the temperature of the alternator itself.
Due to temperature the maximum output current may not be obtained. If such is the case, keep the headlamps on to increase the electrical load.
The nominal output current may not be obtained if the temperature of the alternator itself or ambient temperature is too high.
In such a case, reduce the temperature before testing again.
- The output current value changes with the electrical load and the temperature of the alternator itself.
- Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
- Disconnect the battery ground cable.
- Remove the ammeter and voltmeter and the engine tachometer.
- Connect the alternator output wire to the alternator "B" terminal.
- Connect the battery ground cable.
