So why did GM stamp those 6 volt coil housings with big embossed lettering that read "12 volt"? I guess those engineers weren't able to read back then. A GM "12 volt" coil operates most efficiently at 9.5 volts, at least according to the training material I studied at the GM technicians' training center on Summer Avenue in Memphis, beginning in 1962.
I really don't know what I'm talking about, but I did raise a family and buy and pay off two houses with the earnings from repairing anything that rolls, floats, or flies for over 50 years.
