While it's running the alternator power wire should be seeing between 13.8 and 14.2 volts. I have heard the 1 wire alternators require the engine to reach 1000 or 1200rpm before the alternator will start to charge?
I would let me move this to the electrical section also. https://67-72chevytrucks.com/vboard/...splay.php?f=64
