Humble Listees:
Yet another early morning automotive conversation before work with my
comrades and another unresolved question.....this morning's dilemma is:
Why was positive earth (ground) "used first" - later changed to negative
grounding?
My colleagues seem to think it had something to do with the fact that the
earth is positively charged with respect to naturally balanced negatively
charged clouds so why not comply with nature and make our cars normally
positively charged. I figured that the decision had something to do with
electron flow versus current flow for spark plugs.....it's better (that's as
scientific as I can be) to have a spark originating from the centre electrode
of a sparkplug to control the explosion blast which it would if you believed
that a spark starts from the negative side of 2 electrodes. 'Course, that
argument doesn't hold up with today's neg grounding systems.
So, maybe positive earth got it's start purely from coincidence.....the
positive battery post of the first production car just happened to be close
to the frame so the assembly crew connected it home!!
