Okay so about a week ago i took my car to an auto shop and got my breaks fixed. They couldnt find the part so i had to leave my car there overnight. Next day i remember that forgot to take out some stuff off my car that i needed to go to work with. When i got there i went to my car to get my stuff and saw the radio was ON and this thing i plug in the cigarette lighter to listen to music. I turn the car off n left because i was late. the car was on more then 12hr.. TODAY i saw the battery light turn on. my question is would that make the light turn ON on the dashboard? cuz it Would be more easy to fix.. becuase before my car didnt turn on cuz the battery was low and the light didnt show up.

 

I would start by gettin the battery checked

 

Sounds like your alternator is pooping on you. Otherwise, you got electrical problem.

 

but the alternator looks like the newest part of the car when i got the car it look the cleanest of all the parts in the hood. it been more then half a year since i got the battery but the cheap ones 70$ can it drain that fast?

 

i got it check but they didn't test the battery. he just took out the (-)cable of quick he told me its lose. so im thinking its that.
