This application is actually for a friends Ford Ranger but we have found solutions for both Ranger and Sport Trac's problems through this forum.
As the title suggests the trucks electrical system does not charge above 70MPH. He can visually see the in dash amp gauge gradually fall down when traveling above 70 as well as gradually diming lights. The warning (idiot) light never comes on regardless of speed but in does check OK when vehicle is first started.
My first inclination was bad diode in the alternator but yet no light. Then I thought battery path but when the problem was further diagnosed to being speed related that path was iffy.
Anybody care to throw an idea?
