Just checked an old Oasis report I had...says Ford replaced the battery on 08/09/00 with 32,168 on the odometer. So it's about 3 years old, with about 36,000 miles on it right now. I'll swing by Sam's Club and have it tested, I can pick up a Champion battery there if it's bad. Thanks for the input! Hopefully that was a 3-5 light I got and not a 5-3. I looked up the 5-3 a while back and it had something to do with the main crash sensor... My luck, it's something not covered under my ESP, lol.
