1997 ford f150 4.2 charging system
This past saturday, my trucks battery light came on. Of course, you automatically think battery first, until you consider the fact that the battery was bought with the past 4 months. (I also tested the battery and took it into work to put on the tester/charger) Next thought: Alternator. I replaced the alternator Sunday and even after, the battery light stayed on, and the volt meter just keeps dropping.I question whether I may have gotten a faulty one, which is why I am going to warranty this one today and give that a shot. The load tester says low regulator voltage. Other than a loose connection, what could be the problem? I am trying to get ideas before I go out today and try to figure it out. Alternator is an easy replacement, so that is why I am going to try and see if I may have just gotten a faulty one. I work at O'reilly auto parts, so its no big deal to grab one.
Any suggestions just please let me know. I just replaced one of the battery cables, so I am going to mess with that a little bit today also so I can see if maybe there is just a loose connection. Hoping to get this taken care of by tonight considering I need the truck to drive about 120-130 miles every day. Had to borrow a car from the in laws this week. Have a mustang, but it doesn't have legal plates right now. (because its for sale, didn't want to renew if I am going to sell it.)
Thanks for any help.
