The Electric starter/generators of the 1930s & ’40s were 12 volt, The first modern starters of the 1950s were 6 volt through 1956. The 12 volt system offered in 1957 had an optional generator which only put out ten amps and didn’t start generating until 1,700 RPM. The Motorola alternator offered on the deluxe V-4s could output 35 amps, and would charge at an idle. . . 😀
