Check charging system

Bought it last Saturday

Did you check the voltage coming out of the new alternator? Also, check the tensioner and serpentine belt to make sure it is not slipping. Does it occur during a turn a turn or when the A/C kicks on? If you belt tension is down, the additional load may cause the belt to slip.

How will I know if the belt is slipping. I replaced the belt as well about 3 weeks ago.

It doesn't occur when I turn or turn the AC. It usually will pop up quickly then goes away. Like if something is loose. And cause it to get that message.

Where did you get it from ? If it's Advance Auto or O'Reilly you can throw it in a canal. Use either NAPA or Motorcraft branded alternators, and make sure it's a 110 amp alternator, not the 135 amp.

Lol yea it was from advance. I called them earlier to confirm it was 110. I wanna add a additional ground wire. How can I do that?

FYI. I had an accident late last year. So the truck is been giving me issue. This is the main one.

I wouldn't waste any more time on that alternator. It's a POS. You can tell 'em it's setting off your battery warning system and try an get a refund, or try another alternator, but it'll likely be the same. They do show a Motorcraft 110 amp alternator in their inventory, you'd have to ask for it. It's about $60 more than their crap store brand. Maybe you'd have better luck. Tell 'em their store brand is triggering a charge problem and you want to exchange it for the Motorcraft F40003332750MTR unit. They should do that without too much hassle.

I was having the same message with "check charging system", new alternator and new battery. I followed the advice above about putting in a 110A alternator (I had a 135A alternator with no nav system) and sure enough, it went away immediately!
