It is probably the brush pack/voltage regulator. Either it needs to be replaced or needs to be re-seated in the alternator. I just had one recently where I had this exact same situation...no charge light unless I grounded it. I removed one screw on the brush pack (the one that was easiest to get to with it still in the car) and jiggled the voltage regulator/brush pack around and then re-installed the screw....works perfectly now.
Hope that helps!
