I (and I think, Botherton) was referring to the battery-motor Neg connection. He begins the paragraph with: "GROUND refers to a connection made to the earth itself"....(paraphrasing)"On land, through a pipe driven into the ground, on our boats, ultimately to Seawater". He goes on to say that ideally (and by ABYC recommendation): "Each item in the circuit is connected by its own pair of wires and the common ground carries no load current." (except on my boat on which I now realize, it completes the circuit for the Alt. and Starter!).
Anyway, I was specifically asking how GROUND "will supply all (charge) we need". (My boat notwithstanding!)
