1988 F250 7.3l >>>battery Light<<< - Ford Forums

My battery light stays ON when I first start the truck. It goes OFF after 2-3 miles. Sometimes it is intermittent... the ammeter gauge shows low voltage when light is ON but normal level when light is OFF. I've recently replaced the alternator and both batteries. WHAT'S GOING ON????

I have 96 7.3 and mine does the same thing. i just see it as being normal unless anyone else can prove otherwise. you have to figure theres alot of power being used between glow plugs and starter also most glow plug systems are still on for atleast a full minute even though the light goes off.
