Re: 2005 e350 6.0 Diesel Heavy Duty Alternator
I don't know what alternator you have, but I DO know that when it gets hot you can figure it puts out about HALF of what's on the spec sheet. We have a boat that has 4 big batteries (8D's) and could never get them topped off. Finally the alternator went Tango Uniform and the guy at the alt. shop said that when hot, the output dropped dramatically. We swapped out for a large frame alternator with almost double the output, and the problem was solved.
