 Sounds like you have a shorted diode in the alternator. Put your meter on current, connect it in series with the battery, and disconnect the fat lead on the alternator and yank the plug from the alternator. If the light goes out and the current goes to zero, there you have it!! Also, that faint glow should go away when you disconnect the alternator.
