In my best Homer Simpson voice, DOH!
I meant the regulator.
The regulator commands how much power the alternator makes, by controlling how much electricity goes to the field coils. If it's shorted then the field coils have power all the time, even when the engine is off and thus draining the battery.
It would also be making the alternator produce the maximum amount of power that it can, and over charging the battery.
The test you did with the light, do that again, but this time disconnect the alternator. Being careful not to bump the charging wire against anything metal.
You probably have the fuseable link in the correct place, as you said, it wouldn't start.
