you could have a drain with the car off....thats easy to verify..

or you could have a flahey regulator...I had one that gave those exact syptoms...90% of this time it was fine...out of the blue it would dicharge the battery overnight and sometimes it would overcharge with 17.9 VDC.

You can get regulators for as little as $29... and it takes 5 minutes to replace.
