Hmmm...so when ur car is off it gets drained too?? If it is "draining" while you are in neutral & or on, your battery isn't getting a recharge from ur alternator or a bad charge. This may be a bad wire or short.
Stupid Question....have you checked the Trunk light, dome lights, and cig lighter for elec. shorts??
Another thing..does this car have aftermarket pullies??? Sometimes the "new" alternator pully will cause a loss of charging and thus drain the battery some or a lot...so I have heard.....?
