positive ground

That which we call a positive by any other name might be a double negative; or positive.

Water flows down hill, higher potential to lower potential.

Power flows out of a generator to a load, unless you motorize the generator (turn it into a load) or run it at reduced voltage from a larger power source, electric grid, then it becomes a voltage reducer in the system. Var generator or absorber.

Lastly vars are like the foam on a beer, nobody wants the foam or to deal with it, but its all part of the experience. So enjoy. Thanks Neal E.

Electron theory, conventional electric application, AC & DC wiring not comparing apples to oranges. Black wire in 120 AC=hot (potential, but int DC wiring black is the ground. EE engineer told me once I was crazy as I was wiring up a AC duplex in a house. Theory vs practical application.

So in practice, on a tractor, consistency and polorization is the only thing important in a system with a generator. However if installing an alternator, you'd best get those diodes working in the proper direction. Neg ground alternator must be hooked up to negative ground battery and vise versa with a positive ground alternator, and yes they do make them.

If this is true, then a multistrand 12 gauge wire has a much greater capacity for electron flow than a single solid 12 gauge wire?

To the contrary,,,,, ,,,Theres no source of COLD... Look up in the sky n all you see is the sun providing heat n theres no big ice cube supplying cold is there. Cold is just the absence of heat....On what we call a cold day its not really cold, its just that theres not much heat in the air lol cuz of the earths tilted rotation and the sun and its heat energy location

Similar is how when we go up in elevation on a mountain it feels cold cuz theres less heat cuz theres less air molecules to trap n absorb n store the suns heat energy.

You cant create or destroy energy ONLY change its form and about all I remember from Thermodynamcis class was "heat lost = heat gained"

Sooooo oo what an AC unit does is to extract heat from the house n dump it outside, just stand outside one n feel all that hot air lol The heat lost from inside the house = the heat gained wherever it was discharged to. Similar, a refrigerator DOES NOT put cold into the box, it removes heat from it (what makes it feel colder in there)

Funnnnn nnn discussion yall take care now

PS I also believe its impossible for planes to fly, how they keep all that weight suspended in air lol John T

As far as current flow (the movement of negativley charged free electrons) it only happens when theres FIRST a potential voltage difference and a conductor of electrons (a load and its associated wiring) between the potential voltage difference terminals such as say the + and - terminals on a DC storage battery.

As far as current theres BOTH the movement of electrons and then there's movement of the "Holes" left behind by the vacated electrons (The Hole theory I believe its called). That might (or may further confuse lol) help a layman understand internal battery and external battery currents, cuz if what may be labeled as "conventional current" is flowing from + to -OUTSIDE the battery, then INSIDE the battery theres gotta be current flow from - to + .

As best I can recall (hey its been 40 years ago at Purdue lol) our instructors referred to + to - current flow OUTSIDE the battery as "conventional current" while current flow INSIDE the battery from - to + as "electron current" (Thats the likes repel and opposites attract stuff, - charged electrons flow away from the - terminal towards the + terminal)

A good conductor of electricity like copper has free electrons that can easily be given up in its outer orbit, while a poor conductor like glass does not have such. If the negatively charged electrons are knocked out of their orbit as current flows in one direction then what may be called a "Hole" (a vacancy) is present and while electrons flow in one direction those "Holes" (vacancies) flow in just the opposite direction.

Whewwwww wwww I had to dig deeeee eppppp p in my old brains hard drive to dig that out so nooooo ooo warranty express or implied lol

That all said a genny can still work n charge at EITHER Pos or Neg polarity provided its properly POLARIZED and dont anyone get hung up or overly confused about Pos or Neg ground cuz all that consists of is bonding a huge hunk of iron (tractors frame) to one battery post or the other, while the charging and current flow and the laws of physics and battery theory still goes on REGARDLESS of which battery post you hung some iron onto.

Forgive me being rusty on all that "conventional current" n "electron current" and "Hole Theory" stuff its just been tooooo dernnnnn nn long lol but for a continuous current to flow from the battery through an external load n return to the battery, then inside the same battery theres gotta be current flow also and one is + to - and the other - to + so all the terminology and "conventional current" and "electron current" and "hole current" is sort of how I was taught..... .

I hope that sufficiently explains the situation
