I went by the mechanic again today and he tested the battery and told me that it was working properly, he told me that something in the system was draining the battery, so I decided to try and determine the cause of the drainage. I read on another post how to go about determining the fuse location, so I proceeded to pull fuses one at a time measuring the amp draw each time. As soon as I disconnected the positive side of the battery I noticed that the voltmeter started at -.400 amps and went up a pretty much a constant rate of about 1/100th of an amp per second. This continued with all the fuses I pulled until I got to fuse #13. The fuse card says that the diagnostic, hazard warning system, clock, central locking system, control unit memoroy of seat adjustment system, and electronic radio are all run of this fuse location. Oh yeah, after having the battery disconnected for maybe only 10 minutes, the voltmeter went all the way to 5.0 amps when I got to #13. I am almost positive that the vacuum pump is the cause of this battery drainage because I started having problems with the driver's side lock around the same time (after a girl rear ended me). I will search for the location of the vacuum pump and provide an update.
