Hey all, I replaced my alternator over 10 years ago with a Ford Remanufactured alternator. I don't use my truck that often, mostly for towing. Anyway, it seems that it has given up the ghost as my batteries have suddenly died and they are only between 3 and 4 years old. I will be taking the bats to Auto Zone to have them load tested, but I suspect the alternator is the issue. My question is, does anyone have a recommendation for a replacement alternator? Is a Ford remanufactured alternator the way to go or is there a more reliable alternator out there to buy. I don't think Ford offers "new" alternators... or do they? In short, please steer me the right way on my next likely purchase.

 

Check FICMrepair.com (link to alternator page below), they have a pretty good reputation for 6.0 alternators.

Hey there Tim, long time no post!

Here's a recent thread with some good info in it, bottom line was go with a 140A NEW unit unless you have large electrical draws - the thread tells you which ones and where to buy: Take care!

I have a DC Power "stock replacement" alternator which at the time was 170 amp output (i believe). It was the highest output I could get without upgrading my charging system wiring. It's served me very well since 2014. I think 180 amp is the lowest output DC power alternator you can get now.

 

Thanks, I hadn't thought of ficmrepair. Last I read they had a good reputation.

 

Three to four years for some battery situations is not abnormal, with infrequent use and no maintenance charging. Declaring an alternator the issue when no mention of a battery light (charging light) may be premature before going into the wallet lions den.

The battery light tells you the alternator is not charging.
