System check

I just replaced both the alternator and battery in my 05’ mustang get but the check charging system still comes on any ideas?

Hmmm. Any other symptoms? Where did the alternator come from/what brand? If aftermarket from a parts store, some have been known to be bad right out of the box.

Usual recommended alternator replacement for the 2005-2009 Mustangs is to try and get a 2010-2014 alternator from Ford. Better than the ones Ford originally put in the 2005-2009 cars.
