2001 Ford Mustang mileage: 69,000. My son's car failed to start after school on Friday even though it had run fine that morning. We jump-started it thinking he had left something on. We took battery to get charged and they suggested new battery so we bought one and put it in. The car immediately cranked, but after setting overnight without driving the car for more than a few minutes, it was dead again this morning. Nothing has been left on to run the battery down, and I thought it might be the alternator, but since we didn't run it, yesterday I didn't see how it could have pulled all of the juice out of the battery if it was alternator.I feel like something is running the battery down, but don't know where to begin to look. Any ideas?
