Engine won't start

[rbeldua]

Hi to all,


I have a toyota 2008 yaris, battery is 3 mos old and after 3 to 4 engine start and drives around with A/C on and lights on, it losses power and it won't crank up the engine. I know the alternator is working as I disconnect one battery pole connection and it still runs. It seems as if its not charging via alternator.

can anyone help me out here, I am kinda lost with this one.
