2000 Taurus SE - hit curb, now battery's dead?
So my girlfriend cut a corner too sharp, and ran over a curb with the passenger side back wheel (in a grocery parking lot, going maybe 10mph). When the car came off the curb, she heard a loud thunk. Parked the car, did her shopping, then drove off. And then, she started loosing power....tachometer, spedometer, all dashboard went dead, car starts surging and cutting in and out, and eventually dies. I checked it out after work, and didn't see any damage to the rear where she ran up on the curb. I also checked all connections to the battery and starter, and the ground, everything looks okay, but the battery's dead. IS this a strange coincidence, or could driving over the curb with your back tire somehow break something loose that would cause this?
I've pulled the battery and tried charging it, but it won't charge over 64% for some reason (it's only 3.5 years old, never had a problem with it before). I couldn't really get a good look at the alternator last night, as I didn't have a flashlight or any tools, and it's not easy to get to from above the car. I'm guessing it could be a bad battery, or the alternator went out. But I'm just bewildered that this happened exactly at the same time as hitting the curb. I read somewhere on this forum that a loose fuse could possibly cause the cutting out of power, but would that relate to a dead battery?
In any case, I'm taking the battery back to the store for a replacement (hopefully), and then I can at least get the car home where I can dig into this more. Just wondering if this makes sense to anyone else out there, because I have no clue how this issue could be related to hitting a curb, and I'm completely open to the possibility that this is just coincidence (but I still need to figure out what's wrong with the dang car).
Thanks for any input..
