Last week i back my car out of the garage and all was well, then about 45 minutes later i started it again, and all my presets were gone on my radio station, and that only happens like when the battery has been disconnected, oh well didn't pay attention to it, it's been fine, worked fine this morning, then i went to leave a buddies house just now and i went to start it and i turned the key half way and everything lit up fine then went to start it and nothing, it was like the battery was dead, so i got out and left the key half turned and when i closed the door everything lit up again, then same thing tried to start then nothing, so i popped the hood and turned the negative battery cable and it didn't feel like it moved but then my buddy went to start it and it started up, so i dunno if that was little lose or what, what do you guys think?
