Car isn't on, it's just sitting, so it's irrelivant.
Brian, does the car have an aftermarket headunit or alarm? I'd check to see if you have a short or maybe there is a lose ground
Nope, nothing aftermarket, this is as plain a car as you can possibly buy from Mitsubishi. Ground is NOT loose.

That is an EXCELLENT idea, and most likely the cheapest solution. I'll bet I could use a marine batter switch to do just that. I may end up doing that, hopefully not, but it may just be the interim ticket until I have some cashola.

I think the best course of action is to do what Noodles recommended. Connect a multimeter in series with battery (in DC Amp mode) and look at the current draw. Pretty easy to do, just remove a battery cable and connect one lead to the battery terminal and another lead to the battery cable. Turn the multimeter on and check what the current draw is. Make sure the key isn't in the ignition and all the doors are closed. If it is more than .05A then you have something turned on that should not be on. In this case, pull a fuse and check the current draw. If the draw goes down then you know the problem is with that circuit. If the draw doesn't go down then go on to the next fuse. Be sure to read noodles' post as well as it has a bunch of safety stuff so you don't blow up your multimeter.
My electrical and multimeter skills are severely limited (impaired). I do have a multimeter, and perhaps can check some things this afternoon.
Battery is currently on the charger.
I have pulled all the fuses possible in the engine compartment and in the passenger compartment, that allow the car to still start.
I'll pull the charger in about 30 minutes, and see if it still drains down. If not, then the problem was with a light or accessory circuit. If it does drain down, at least I'll know it is none of those items I pulled.
Thanks to everyone for the help and the support so far!
Note: Derick - EXCELLENT info, thanks, I'll run through that list.
