Re: Alternator dilema

Don't be confused, man. You do want 14vdc or better! Apparently later genIII LS's, and beyond, have alt's that are regulated via the pcm, bcm, and the generator battery control module or gbcm. When the alt. doesn't have ALL of that hooked up, it defaults to just over 13 vdc all the time (my situation). This alternator thing has been going on for quite a while here on the site, and elsewhere apparently. Even after my truck has been together for some time, I'm still learning new things. Just buying an aftermarket harness and plugging it in does not guarantee a perfect solution. From what I've read so far (been all day researching this, shudda stayed dumb and just accepted the 13vdc output), I've either got to modify the DR44g, or change to an earlier style AD244, unplug the harness from the alt/pcm, and rewire the alt. to accept a switched 12vdc source with a resistor added to it ( I might have answered my initial question?) Hopefully. I'll get some kind of response
