Maybe in Saskatoon because it's metric. But in the US the factory alternators put out anywhere from 36 to 60 amps. No way you can run 60 amps through a 14 gauge wire. Not even 36, I doubt. Maybe in a vacuum as a light bulb. But not in your harness.
The only way this can work is if the relay is off during cranking. I could check that, but like the Carnival barker on the Simpsons who doesn't check to see if Hitler is still in the trunk of Hitler's car, "I'm a busy man, ain't got time to look". But I'll test it later.
I checked with an electrical engineer and his take was that the cranking battery should always have higher voltage than the camper battery and so it provides the amperage needed to crank. I'm not sure about that, and there's still the case of someone throwing a charger on the AUX battery such that IT has more voltage.
PS: Just giving you grief about Saskatoon, I'm from Regina. And it never occurred to me that it rhymed with anything until I moved here!
