[Elecraft] OT: 2017 Chevy Silverado 1500 power outlets

[Ron D'Eau Claire]

Clay, I believe it has to do with danger to your equipment should the
connection between the battery and the chassis open. In that case all the
current to all the automobile systems, from starter to lights to ignition,
radio, etc., would flow through the ground path provided by the radio if it
is connected directly to the negative battery terminal. Since that can be
100's of amperes when starting the engine, no radio is likely to survive.
