My 2003 7.3L F-350 is having problems with the alternator i think? I replaced both batteries last week it has a very hard time crancking over anda lot of timesit doesn't even crank, it still has the original alternator, i have many accessories ran off of it, driving home the other day my radio kept turing off and on, Ihave had to jump it about 6 times within the past week.Once i get it runnning i let it sit for about an hour then drive it around a little and once iturn it offagain it wont start up like it usually does.I just recently moved from South texas to Wyoming i dont know if this has something to do with it? Does anyone have any ideas of what might be wrong????

Thanks

 

might b starter what dose volt meter say with engine running

 

Doe you have a gauge in the dash for the charging system? See where it registers with the key on and see if it moves up when it is running. If not, then your altemator is probably bad. Ususally, you will have a battery lite come on when it stops charging.

 

Thank youvery much for the advice, when i out it on the tester after i got it running it was puching .3 amps so obviously the alternator was my problem so i replaced it over the weekend and now it is running great!!

Thanks
