Okay, so I've had my car apart and sitting for two weeks trying to find the time to finish an IPOD install. The battery has been disconnected. Had some time today and got it all hook up, tested and buttoned up. The IPOD install went great and it sounds awesome. After cleaning up the interior, I went to start the car and it turned over a few times and then made the usual clicking sound of a dying battery. So, in disgust, I went inside had dinner and then went back outside to see if it would start. I pull the door open and the horn goes off and the lights are flashing, almost as if in some kind of code before it quit. The engine turned over a few times but wouldn't start. I get the same thing with repeated opening of the doors. What’s up with this? As to the battery, I don’t know that I've ever changed it and the car is an 06 for which I bought with only 9k miles on it. What are you guys doing for battery replacement? Do I need to acquire another Motorcraft or is there a better alternative?
