So I just got and put on the new cable and realized that the wrong cables were on the wrong terminals,and they were there for a couple of hours!I'm so screwed because now,after switching back the cables to the correct terminals,there's still no signs of life,not even a click.So I went back to Autozone and they checked the battery and said that it's ok.I guess the only thing to assume now is that the computer is fried.So if that's the case,how much is it to get a new cpu for a f22b2 and is it something that I can replace myself without any special tools?
