The regulator or the diode bridge in the alternator could be going out and causing the drain, if nothing else is.

I wouldn't think that your current draw would be stable if you had it spread around multiple circuits, and having them all fail at once is not too likely.

If you have a Schucks, O'reilly's or the like that can do the free alternator tests, I'd consider pulling it and having it tested.


I'm not too familiar with that particular model, so I can't say just what else might be unfused, or not fused in the main fuse box.
