So for the third time this summer my truck has been dead when I went out to start it. The other two times have had me replacing my alternator. So now is my question, what could be causing my batteries not to charge since I have put 2 new alternators in already? Something shorting out? Radio being on causes it to drain? Im lost and have no clue where to start and all the auto parts stores will do is just put in another alternator. If anyone has any ideas of what I can check please let me know.
