So quite a blunder on my part, I had to swap in a battery from my truck into my car. Somehow (maybe the beers from working on other projects) I installed the battery backwards. I grounded the positive post first, then when I put the positive wire on the negative post, it arc'd and probably fried something, hopefully just fuses. I checked the fuse panel next to the battery, only one was blown. I replaced it and heard the fuel pump prime, along with the cd player doing it's loud loading sounds. However I got the theft lock icon up, and my key is stuck in the ignition. The car is acting like it's stone dead save for the cd player sound (dead screen) and the red light theft icon. It was at the end of the day and I didn't have my power probe with me, so hopefully this week I can poke around with that and see what else went wrong. I checked all(?) 3 fuse panels (trunk, driver kick panel and underhood) and I couldn't find any other blown fuses. I even tried swapping around matching relays to see if anything worked. Nothing. Did I really fry something badly, or is there a little fuse somewhere I overlooked? The battery fuse block seems fine, although I might jump it with the power probe to ensure that it's good.
