Default Re: Stupid Question #2: how does an iron frame act as a ground on our cars

well gang, I confess I fibbed a little bit. I read in my book about Henry Ford and the D T & I that when he bought the line, it had iron telegraph wires, but they had corroded significantly.


But if iron is an acceptable conductor, I don't see why it doesn't replace copper, which the US is not well-endowed with.
