Abstract
A method for performing a diagnostic test of an alternator, a test arrangement and a vehicle are provided. The method may include running an engine, providing a signal representative of a pre-determined environmental condition to the alternator, providing an output voltage and output current to a battery based on the pre-determined environmental condition, and determining a battery voltage. The method may also include comparing the determined battery voltage with a pre-defined reference-voltage representative of the pre-determined environmental condition and outputting an approved test result if the difference between the determined battery voltage and the pre-defined reference voltage falls within a predetermined range.
