Car is dead. Battery problem?

Hay fellow San Franciscan and firebird owner. Except I have a 2001 trans am ws6. My best suggestion is to but your bat. on a trickle charger over night. Have the bat load tested. to verify that it is good. Should hold min 9.6 v under load at 200amps 15 seconds. Check for loose or corroded terminals. Just for your info.That little green lite don't mean much. A bat has 6 cells. That green lite only measures the electrolyte of one cell. There might be a short or u can have defective plates.Either way if your bat. is good. Check your charging system. simple way is to just but a voltmeter on bat. should read 12.5v enginee off bat fully charged. Start engin and check meter. should read 13v or above apply load. (turn lights or accessories) on. meter should rise around15v. If all is working properly. If no failures are found than it's time to look for a parasitic draw. this can take some time and should be done by a qualified tech. It involves looking for anything that should turn off after the key is removed. Since we are dealing with a late model it should be noted that it has in it's design a function known as keep alive memory That basically means that the BCM runs a check on the cars electric and security systems and turns every thing that is not supposed to be on, off. It allows only programed functions to operate.Like the sentry system. As for your seat warmer.If the car is running the alt will pick up the extra load.
