ALternator question 1970 Swinger 340

Thanks for the reply. I struggle with postings so i hope this reaches you! I did run some simple tests, I put a meeter on the battery and fully charged it reads as it should 12.5. Then started the car put on an electrical load (lights and radio) and sure enough it goes to about 11 volts. I aso bought a cheap voltage regulator from auto zone and got the same reading when I repeaded the test. The meeter in the car is not working but neither are the dash lights or Wipers! That's next. Any thoughts?
