THANK YOU ALL !! I have a 2011 ford edge limited and i replaced the alternator and then shortly after i got the check charging system code warning and occasionally if i drove it too long it would just shut down and i replaced the battery the serpentine belt and went through two alternators before seeing this then i replaced the alternator again with a motorcraft and IT WORKED !! Thank you all this fixed all my problems and i am so very grateful !!!
