Question about 2003 Ford F150 Regular Cab
By clearing the problem that the battery charge circuit is having.
Did you check the Alternator charge circuit fuse ( engine compartment fuse # 11 ) ?
IF this tests good with a meter on both sides, next is to check the harness where it plugs into the alternator, some times the contacts can get corroded
If this has power from fuse #11 above, next is to check the brushes in the alternator ( watch those springs when you check them ) :
You might also need to have the battery load tested, as well as having the alternator bench tested for the RPM range.
