So my 02 gt sits because Im not supposed to drive at the moment because of my epilepsy so I take this time to fix her up. I noticed a week ago that the negative terminal on my battery was corroding and fell apart while I tried to tighten it down. It scared the crap out of me when I was installing a new hood release cable and all of a sudden I heard a tick and my radio shut off lol. But anyway I got a new terminal and installed it yesterday but when I went to start it the battery was pretty much dead. I jumped it with my 07 gt and took it for a spin to charge the battery and it turned right back on afterwards. Ill try again on friday to see if its still dead. Now for my question, is it normal for the battery to go dead while its unplugged for a few days? I checked the battery with a multimeter and with the car off it reads about 12.8 volts and with it on it reads 14.5 or so. Is that normal? On a side note, Ive noticed the battery light will come on for a second sometimes at high rpms and come on for a while a couple weeks ago but went out after 10 or so mins.
