whats the normal charging voltage on my 81 xs? Just bought her two weeks ago and today was the first day i could work on it. Happy to say she fired up but ran at 12.85 volts with out fluctuating...im an ase cert. auto tech and most cars/trucks charge at 13.5-14.5 so the 12.85 seem ok but im not sure?
