The battery cables look relatively new. The only thing that looks a tad rough is the engine ground, but I think thats just grimy. The terminals are new as well, I forgot to mention that. I did measure the resistance and there was nothing worse than a few ohms.One thing that I can mention because I just remembered it, if I start the truck and then disconnect the negative lead from the battery, and then run a voltage test between the positive terminal of the alternator and ground, its up at 14.5v. When I re-attach the battery, it goes back down. Any thoughts?
