Check your alternator belt. It might have slack/be loose.

Is the alternator working in the car? If not, did you check fuse 15?

Have you checked for parasitic drain?

Disconect battery and wire test light up to battery and disconected lead then start pulling fuses one at a time,when light goes out you have normally found the circuit with the problem.

car off = 12.5

car on = 14.08

car on wit high beam and heat on max = 13.6

is this a good sign? is battery recharging again?

Get a test light, take off your negative terminal, hook up your test light between your negative terminal and your battery post. Make sure there is nothing on or it will give you a false test, if your test light, lights up then you have a draw somewhere.
