Alternator Problems!! Anyone else have this going on?
I have an 05 F250 6.0, in september of 2009 I replaced the batteries and alternator in it I bought the same alternator that came on the truck. In oct of 2010 the alternator went up. So they warrantied the alternator for me and I replaced it, then in february of 2011 the alternator went bad again, I tested both batteries with a load tester and batteries are good, so then we did some research on why my truck was eating alternators, ford said because of the date my truck was manufactured i needed a diff alternator so we put that one on and it went up last week while I was on vacation so I had to replace it. So this is the 4th alternator on my truck in 2 years the only things I have on the truck is an HID kit, and my Sct Livewire. Anyone else having these problems or have had problems like this before? And when the truck is parked everything is powered down and I cant seem to find a drain on the truck? Any help would be greatly appreciated...thanks
