Chrysler converted to 12 volts negative ground, from 6 volt positive
ground, in '56 along with Ford. GM began the conversion with its
senior cars in '53 and by '55 all were 12 volt. Packard, K-F, Nash,
Studebaker etc. followed a similar pattern.
BMC cars were using 12 v, positive ground systems in the post-war
period which means they probably used them before the war. My
Standard Vanguard is 12 v positive ground.
