cable to terminal B and connect voltmeter cathode to ground safely.) 6. Install engine tachometer. 7. Connect battery cathode cable. 8. Keep engine cover open. 9. Check if voltmeter reading is the same as battery voltage. Remarks: If voltage is 0V, it means the wiring between alternator terminal B and battery anode is disconnected or the fuse is broken. 10. Keep lighting switch ON and start on engine after headlamp lighting. 11. Headlamp is adjusted to high beam position and heater blower switch is turned to large volume position. Engine speed increase to 2500 r/min and the ammeter shows the max. output current value. Limit value: 70% rated output current Remarks: Rated output current is represented on alternator nameplate. be read quickly. Output current changes with electronic load or alternator body temperature changing. value even alternator works well. If so, it may open headlamp to make battery discharged or open lamps on other motor vehicles, which will increase electronic load. And then make test again. If alternator body temperature or environment temperature is too high, output current often can’t reach to the regulated current. If so, wait until alternator is cooled and then make test again. 12. Ammeter reading should be higher than limit value. If it is lower than limit value but alternator output cable is ok, please remove alternator from engine and check it further. 13. Keep engine running at idle speed after experiment finish. 14. Turn ignition switch OFF. 15. Remove battery cathode cable. 16. Remove ammeter, voltmeter, engine tachometer for test. 17. Alternator output cable is connected to alternator B terminal. 18. Connect battery cathode cable. |
