Sorry for the late update - working crazy hours and working some more crazy hours to pay for the stuff I want to do with the car.
Ok so retested the alt one more time and the VR one more time - and it turned out it was the VR - ordered the electric (digital??) one and all was fine.
Latest challenge is replacing the old alternator belt - some of my starting problems and hard starting when hot I think is related to the belt at the end of its life and slipping although no sounds.
Headed out to Can tire or part source to grab a new one tomorrow. On the road and loving it.
Can't find any youtube videos on replacing the belt - any tips I need to know or is it pretty straight forward? (my car has no A/C or power steering.)
