Potential is the key word.

No!So, if the switch or the pump became connected to ground by immersion or partial immersion in an electrolytic, the 12v positive would create a completed circuit through the pump?
OK, so the electrons are coming from the negative side of the battery and flowing to the positive side. It is convention (started with Ben Franklin) to state that the current flows from the positive to the negative. This happened long before anyone knew anything about electrons. Ever since then, that is the convention and how it is spoken of - current is said to flow from positive to negative, as incorrect in the physical world as that actually is.Why are the electrons not coming from the negative side?
I think I see what you're saying. I misread Collier again and didn't realize he was saying, in case of a compromised system?
This is what Ben's letter to the Academic world did...It is convention (started with Ben Franklin) to state that the current flows from the positive to the negative
You've lost me...In a PM, with Will last night, we got it straight.
This is what Ben's letter to the Academic world did...
"The single most important discovery noted in these [Ben’s] letters is that of polarity, that is, he found that all electrical potentials were not equivalent, but could be observed holding either of two opposite charges. To these he assigned the names we still use, positive and negative. Unfortunately, from our point of view, he assigned them in the opposite sense to our understanding -- "positive" meaning a deficit of free electrons -- which is why we now call the electron a negatively charged particle."
He had a 50:50 chance of being right... oops
Electrons Always flow from...
Highest Potential to Lowest Potential
In that example, 12+ VDC is higher potential than a Ground reference of Zero.
PS: I had to invoke the Second Law of Thermodynamics on Will.
Ah, I see where you are coming from. I believe I captured this in my post #25, I just should have clearly broken the link between the battery posts and where all the electrons may come from... Nice, I now know how to explain this better...That is what is confusing to a few. They see a Ground as the SOURCE of electrons.
They see the Battery as the destination.
We seem to be stuck on the direction of electron flow.
Quit worrying about direction of the flow of electrons We have established that Metals are the source.
It is the Potential that causes the flow of electrical current or AMPs. [Energy flow]
It is that Energy Flow that consumes a Zinc.
Perhaps the term "sucks" rather than pushes may be better.. It is only counter intuitive when you are living under the convention our boy Ben created...The Battery "pushes" and the Motor pulls, is the current flow direction. It is counter intuitive to think of Electron Flow.
Thus Ben Franklin got it backwards.
That's in the now more common negative ground systems I used to have an old vehicle that had positive ground system. That one you did the other way...Tangentially related to where to put the switch is the convention of which cable to disconnect from a battery first. Always disconnect the negative cable first. That way if your wrench touches another grounded surface, like the engine, you’re only connecting surfaces of the same potential, so there’s no circuit for the electrons to follow.
Ok ok.. Sucks electrons, but not from the bilge water or ocean, but actually from the...Perhaps the term "sucks" rather than pushes may be bette
While true, AC current normally has little impact as stray current corrosion. Certainly you want to control it, but really control of your AC side has implications more towards safety issues than corrosion issues.Simple...
Any Stray current, AC or DC, can promote faster corrosion rates,
Stop them both.
Hey! That's my tank!
