Generator Charging Problems.....

Can anyone tell me what/how much a factory 1958 Plymouth 318 generator should be charging? My battery went dead on me, but when the car is running the Amps light is not on (once the engine runs for a few seconds). I measured it at the battery with my meter while it was running and only have 12.5 volts. I know most alternators charge at 14-14.5 volts. If my charging system is bad, anyone have a good way to tell if it's the generator or the voltage regulator? Any suggestions are appreciated.....
