02 north face.. my duralast alternators keep dieing about 3 to 6 months apart.. I bought a new alternator and battery together and everything was working fine till about two weeks ago my lights went dim and radio turned off.. so I knew it was my alternator again. I dont get why I'm going through so many alternators? I checked the wiring from alt to pcm and it was ok I check pos wire from alt to the red box on engine and from red box to battery, everything is fine.. the truck does not die and if I give it gas the alt does not go to 14 it just goes to 14 when it wants to and when it goes done to 12 or lower the battery light does not come on.. I just dont get that why when alt is not charging my radio turns off windows dont go up? Maybe I have a electrical problem or pcm?
