The charge light stays on the whole time while driving and sometimes when I close and lock the truck. I replaced the alternator and the battery. The light still stays on. Some other forums have told me that its the ground wire under or near the battery. I cleaned and re-tighten the screw but the light still stays on. The only other ground/wire connecting to the chassis are 2, they connect to the radiator mounting bolts and the frame.
