slimijim,

New to the site and got it specifically for the problem you experienced last year. I have a 2011 f250 6.7 with 129xxx miles. My battery light is on and I cannot find out why. Please help. Ive tested both batteries gotten 12.8v tested the single alternator and I am getting 13.6 at idle. All seems well to me? Where do I go next? I tried to follow your other post about it but am a little slow and couldnt figure out what plugs are what. Any help would be awesome!
