[QUOTE="ttocs, post: 646472, member: 11896"] are you leaving a cell phone or mp3 charger plugged in? If not then you need to to a current test on the system with an amp meter. Disconnect one side of the battery and then connect the amp meter in series with the battery and the wire you disconnected. Now see how many amps it reads with the key off, shouldn't be near 1 amp total. If it is, then start pulling fuses one at a time until you see the current drop. When this happens you have now isolated the circuit that has the current drain and you can then troubleshoot further. I did this last year and discovered that I had a pressure switch on the ac system that was stuck on and it would keep the ac clutch energized with the key off. When I pulled the fuse I heard it click-off and was able to figure it out then. This created a 3A draw which over a period of 2-3 days would kill the battery. [/QUOTE]
