1. A method for performing a diagnostic test of an alternator of a vehicle comprising an internal combustion engine arranged to drive the alternator and the driven alternator being arranged to charge a battery via an electrical connection thereto, the method comprising:
running the internal combustion engine at idle speed; providing, by a control unit, a signal representative of a pre-determined environmental condition to the alternator; providing, by the alternator, an output voltage and output current to the battery based on the pre-determined environmental condition; determining, by a sensor connected to the battery, a battery voltage; providing the determined battery voltage to the control unit; comparing, by the control unit, the determined battery voltage with a pre-defined reference-voltage representative of the pre-determined environmental condition; and outputting, by the control unit, an approved test result if the difference between the determined battery voltage and the pre-defined reference voltage falls within a predetermined range. |
