    Alternator giving out high voltage but low current. Why??

    My friend's alternator (Lucas 40A I think) is connected to one battery. It does get excited and produces 14.4V, and it gave out about 15A for a few seconds, but then the current went down to 3A within one minute, which is too low. What are possible causes of this behaviour?
