my 89 gt is having an issue with the battery losing its charge, Its a new battery and a new alternator but my battery wont hold its charge longer than a day, I cant find the problem, any help would be greatly appreciated.
sounds like you may have a short somewhere. it wouldnt hurt to double check your battery cause just recently i read a thread were a guy got 3 bad batterys in a row from autozone.he finally upgraded to a different brand it was fine.
Id disconnect the battery and check it with a voltmeter then hook it back up and check it again(eng off of course) to see if there is a draw on it..then that should tell you if there is a short..
I had this problem as well.turned out the diodes fried on the voltage regulator causing the short..
