70 + voltage regulator issue

Time to do some troubleshooting analysis.

lets start with what's known.
I had to replace the voltage regulator,
Why?
After installing I ran the car, I belive the new VR was bad as it blew out both my headlights leaving me with high beams only.
Why do you suspect the VR blew out the low beams, but not the high beams?
What do you mean by blow out? Did the low beam fuse/breaker open? Is the bulb filiment broken? Neither of those?

Now all the lights puls or strobe with engine RPM making it real interesting driving at night.

Could be the alternator's return brush is grounding (the one attached to the green wire) but lets not go there yet.

What does the ammeter show?
Have you measured voltage at any time while the engine is running?
If so, where did you measure it?
