Not to poke the bear, but.
During my study time, I was instructed that "Electrons carry a negative charge." This being the case, the electrons would be repelled by the negative terminal on the battery. They would hurry forward to the positive side of life, working along the wires to do the Load requested.
There might be a Monty Python-inspired sketch here, somewhere! :)

Following the method Barry mentions and armed with the tips here, I found the following on the start battery:
13.3 resting
11.80 when selected switched to 2
4.80 start

The 7V drop indicates a dying or dead battery, I think. Concur?

I also maintain my connections. That's why they're all tight and corrosion free;)

Thanks for indulging me in my process, gentlemen.
Yep, if those voltages were right at the battery posts, you have a dead battery.
