My truck recently started giving me the dim lights of death while I was driving it home. After getting it towed I went and replaced the alternator and battery. No problems for about one week and then all of a sudden I am getting the battery indicator and ABS indicator lights on my panel, and then shortly thereafter my engine cuts out and the vehicle goes dead. Checked the output on the Alternator and it read at 12.7 and the battery reads good as well. Checked the grounds from the battery(cursory look) and everything seems fine. Any ideas?

12.7 volts is not gonna cut it-your range should be 13.5-15.5volts while engne is idling -get the alternator load tested-
