Default Parasitic draw from Generator?

Hi all!
I've got a 1950 sedan with V8. The battery won't hold a charge overnight. When I disconnect the battery, I get a spark, indicating a draw somewhere. when I disconnected the Armature lead on the the generator, I got a spark also.
The ammeter shows charging when the engine is running. I ran the generator as a motor by connecting the A and F terminals and running a hot lead to the A terminal. It turned over fine, although a little slow, i thought.
So, I wouldn't think it normal to have a spark when disconnecting the Armature lead. When I leave the armature lead disconnected, I get no more sparks when i disconnect the battery, so is the generator at fault?
