Auto electric syastems evolved from 1955 that was 12 volts in gm but they still had generators and voltage regulators even the first altinators had regulators and it was not till around the 1970 ford had a solid state regulator and I dont remember when the altinators were all solid state that when low batteries stoped for good 12 volts did not do it by it self 12 volts with a generator is not better than 6 volts with a generator.
