So I hardly drive the truck anymore but when I went to start it yesterday there was no power, no lights nothing. Battery read in the mv's. So since it was under warrenty I just took it in and swamped it out. Now Ive noticed that the battery is charging at 15.1 volts. I havent rebuilt an alternator in ages but Im assuming since ny truck is a 93 it has an internal voltage regulator in the alternator and not PCM controlled. Anyone have any experience with this?
 






It should just mount to the back of the alternator.
