New to the forum here. First time posting.
I have an 04 f150 5.4 with 144k on it.
Recently had " check charging system " pop up along with battery symbol. Installed new battery and new alternator. Same warning popping up. Did the PCM reset with battery negative cable unhooked for 30 minutes and followed procedures to reset it. All components of vehicle were working fine on the test drive. "Check charging system " came on again. Took it to get alternator tested just in case I got a bad one. It tested good, putting 14.04 volts.
Now when I start the truck, dome lights dont work along with power windows, radio and all of the gauges. Truck runs and idles fine. Anyone have any insight on what may be the problem? Thanks!
I did check the appropriate fuses for all items not working and all were fine.

 

Is it a Ford alternator? These trucks are very picky, I don't care if it's putting out 14+ volts, non Ford parts create problems. If it is a new or reman, check your grounds.

 

It's a reman from O'rileys auto parts. I had checked the grounds prior to changing battery and alternator. Would a non ford alternator cause all the other components to fail? Thanks CKsBAT

 

Remans never work properly. Always buy a new one. One of the good non-OEM versions to buy is Remy.

Should have checked this forum sooner. Reman alternator from O'rileys was over 200$. Thanks for the link and advice Shir!
