dont forget... it wasnt that i had bad batteries... they checked them always after they had the hood up all day or sometimes 2, then batteries tested fine..
IT WAS the alternator that was faulty the whole time ... sometimes it would charge and then quit leving my bateries on there own then when i go to start.. usually in the winter .. click..click then i would curse like a sailor and in the shop again till it was figured aternator
good luck to all
