The field circuit is controlled by the computer could be a problem there. See below

Thanks rasmataz. What do I need to do there?

Here is another bit of info: I ran a test between the negative pole of the battery and the negative cable and pulled fuses until the light went dim. The radio/cigarette lighter fuse makes the light go very dim. The dealer found this too when they checked it out. I replaced the radio but still have the problem. I pulled the cigarette lighter out and it remains disconnected.

I also hear a hissing noise from the passneger footwell. It's like the noise the air conditioner makes but the AC isnt turned on. I get a lot of dripping water under the car when I park it, even on cool (55 degrees) days. I checked and its just water.

If anyone can help, thanks.

I gave you this because the alternator might not be putting out and you're running only with battery power without the help from the alternator due to a problem with the field generation controlled by the computer-something like a built in voltage regulator not maintaining the output of the alternator.

The best way to check for the parastic drain is to use an ammeter-see below the light should go out when you pull the fuse on the radio/lighter-25milliamps and below is allowable due to the vehicle memories-radio/clock etc.
