I killed my battery!
I was out working on the Mirage yesterday testing out the glove box light mod I've been working on. I had it setup all nice since it was 4F outside. I had an electric heater going inside the car and it was about 35F in there. However, when I went inside, I thought I would be going back out and forgot to take the key out of the ignition, and it was in the 'on' position. I didn't notice because I turned off all the bits that would indicate it was on so I wouldn't drain the battery...
So, its on the charger right now. Hopefully I didn't toast it for good.
