1999 Dodge Caravan dodge caravan has went through 2 new batteries in a week showing bad but now they say I need an alternator
I had my starter replaced in May, then my battery in June now I have had 2 new batteries in a week, I turn it over and it clicks still has power to headlights and interior both times. I was told my alternator is showing low voltage but would this cause a defect in the batteries and make them show bad when tested, really want to figure this out before I am out another 200.00 on an alternator. I am wondering if the starter could possibly be wired wrong as shortly after this is when the battery issue started and if so what further complications can I expect from this. Any help would be greatly appreciated
