Battery good, Alternator Good, gauge shows low voltage.
I have a 2002 4.7 Dak with 118k miles, never replaced anything besides battery and oil changes. Never have had any problems until now. It started with my check gauges light coming on and I noticed my battery gauge went all the way to the L. I made it home turned it off and on and everything seemed fine except my battery gauge was just past the 1/4 mark. Drove it again the next day and it finally died on me. I've researched this problem and all I could find is that, it could be one of three things battery, alternator or pcm. I replaced the alternator and battery but is still doing the same thing. Any other suggestions? What exactly is the PCM? is it the black box with fuses under the hood? Is there a Fuse for the alternator? I checked my connections and were all clean except for this connection to the alternator (i've never posted pics hope this works). I also tried removing the negative cable while it's running to see if it'll stay on, It didn't ( I read mix reactions to doing this since it could mess up the computer).
