Stumped on this electrical problem. My 04 F150 STX 4.6L battery light came, I replaced the battery and Alternator and I drove for a week with the battery light on and now battery dead again and completely off.
Any help to get fix, Appreciated.

Experiencing same issues, new battery, good altenator, P0622
Thanks for the input. Bill and Fast Hampster. First, battery is new off the shelf. Installing the positive cable a small spark. I also hooked up a friends OBD II Blue Point Scanner. NO Codes noted. Started the engine and it came back as a P0622, field short. Check the alternator and field wire 14.0 to 14.3 volts. Computer????. What is the good, bad and Russian
Good morning my 04 F150 (5.4 Lariat, new body) would intermittently give me the "check charging system" message. It comes on whenever it feels like, light doesn't dim, truck runs smoothly. My battery died months ago and was replaced with brand new battery from auto zone. I checked voltage and im getting 14 volts with truck running with or without error message. Altenator was tested (while on vehicle) by auto zone and it was good. Checked connectors and all connections are good.
Did have motor replaced December 2017. Any thoughts?
