"Positive Earth" systems died, (not nearly soon enough in my estimation) about the time that emissions controls requirements more or less killed low price British imports into the US. This happened in the early 70's. Please, please, do not get me started on Lucas electrical systems on vintage English cars.

My comments were to attempt to help a non-electrical person make the transition from things where we can see things (water and pipes) and often have to deal with them, to the world where the energy things can't be seen. - - - - Perhaps my wording also is biassed by the Morris Minor 1000 that I owned back in 1960-1965, which had a positive ground. as did most English cars at that time - the Lucas system. I now have a 1978 Petter diesel engine in my 27' Catalina, which has a negative grounded 12V system. Does anyone recall when the positive ground systems "faded" away?

It would make solving problems Much Much easier. Let's take the case of the Lowly cables, wires, connectors, power sources ..and the energy within.. There are TWO Polarities of DC... One is termed POSITIVE and the other NEGATIVE. Both Very good words. The one called POSITIVE should be called Positive... NOT... the "Hot" or the "Main" or "Source"....

Leave no doubt as to what they are I'm sure one can see the simplicity of using only those Two words. As an example: One can say " I checked the Negative wire" and everyone will know what one did. Don't get me started on terms like... Grommet vs. Cringle --- Stern Rail vs. Pushpit (ugh) --- Ground, Ground Plane or Counterpoise. In good Humor.. I...
