Had charging problems after i put in my new lights. So i put in a new voltage regulator, still no increase. Put in a new alternator, still only 13 volts tops with no load. If you add load, say the blower fan or the lights, the voltage drops and doesn't recover. Soon you are running on nearly nothing. Had the auto parts store test the alt. they managed to get 160amps out of it loaded, but at only 13V. Any ideas? i am stuck until i can get this thing rolling.
