Hey Tony,

I would think not (MSD drain). I would keep looking. Have you load tested the battery to see if it will hold a charge, in the first place? If I remember correctly, you can check for a drain by placing the probes of a VOM between the Neg battery post and a ground. There should not be any negligible reading. How about a "wayward" clock, bulb lit somewhere?
I had a trunk light in my old corolla not go out.
