ok well my old battery wasnt doing to well and today i was driving around and the battery light on the dash was on then when i went to leave to go home the car started then died but i got it to start again and made it home so i went out and got a new battery and changed it today but once i changed it i took it out for a quick drive and the battery light stayed on the whole time and the volt meter stays just above 12 but my old battery it always stayed around 14, but it ran fine other then that, but i was thinking that i just needed to run the car some more for everything to reset so i didnt think anything about it, but when i went to go out tonight the car started like normal and i made it like 30 ft and the car died on me so I restarted it and it did the same thing again but this time the car shut everything down so now when i turn the key nothing happens the dash doesnt light up or the car doesnt even try to start, so right now the only thing that works on the car are the lights when i open the door other than that the car wont move? can someone please tell me what i did to my car lol or what might be wrong with it?
