Hello, I'm having trouble with my 97 4.6 HSE. About a week ago the message centre read "Alternator Fault" while I was driving on the freeway. When I was getting off the freeway the car lost almost all its power but I made it to work (about another mile.) After work (8hrs) it started but didn't have enough power so I towed it home and ordered an alternator. Two days ago the alternator got here I installed it, but the battery was dead, I left the battery charging all night long and tried again in the morning and nothing. I checked the gas shut off and turned it back on and again nothing. I took the battery to get checked out and its good it reads 12.9-13.5 volts ( Just bought it less than a year ago.) When I try to start it just clicks but it won't start, it kind of sounds like the battery was dead (obiously not the issue right now.) Any suggestions?
