I replaced the reman NAPA alternator and it did not fix the problem. The one I took off which only had less that 120 miles, which worked fine till then.. when I pulled it off the rear bearing looked blue like the rotor shorted out.. I was only getting 12.64 volt off the large lead.. Put the new one on, still not charging,, getting 12.64 volts off the power wire on the back of the alt... I installed a electronic voltage regulator when I restored the car,, all new wiring harness.. I'm thinking it fried the new regulator also when it shorted out.. But I still should get 14.2 volts out of the back of the alternator with the new alt. even with a bad regulator right? Amp gage works goods,, it shows discharge when lights are turned on.. Thanks for your help.. 
I think Stumpy is right about the regulator but why not take the alt back to NAPA and have them test it? most auto parts stores do that free of charge (pun intended  )

does it change when you speed up the engine? Old style Mopar alternators didnt put out much power at idle speed. you can also start the engine and pull the battery terminal off, if it dies the alternator is dead wiring bad or regulator, if it stays running you may be OK.
