Have a 1994 Cadillac Eldorado with 77K miles, battery went dead and replaced it with a new one. Somethings draining the new battery over night. Anyone having or had this experience. Must be a ground short some where. Getting a small flash at negative battery post when I touch the ground cable to the battery. Might mention that the computer says that my ac system needs to be recharged..low on freon...any connection?

Thanks
