I figured out the problem.. silly and basic.. the negative cable on the car has 2 additional grounds off the rear portion on terminal... One goes to ground out the cps. When it would move a certain way. Or hit a bump. The car would cut out due to car runs off battery ...sometimes in would fire back up... From the cat doing that and cps having a bad connection it kept blowing regulator in alternator... You would of never new its was loose unless you grab a 10m socket and tighten that little bit of loosened wire did a lot... 5 alternator later problem solved..
