Beyond that, all I can find are anecdotal and largely

corrosion" mantra.

Good luck

also be advised that Copper wire in the presents of Battery Acid fumes
corrodes extremely quickly into copper sulfate, (Blue Powder) and that
doesn't conduct electricity very well at all. The tin plating provides
a good protection from this type of corrosion, the same as it does for
Salt Water vapors.

Good point but unfortunately the only wire of sufficient conductor area
(16+mm^2) I have been able to find that goes anywhere need the batteries
is just untinned copper. In this case I have used welding cable because
it has better insulation than other stuff I have found. I have also
sealed the ends well.

If the stuff I am talking about here (1-2 mm^2 from the dis panel) is
getting battery fumes I am in real trouble!

There you go, Bruce....ruining good towing jobs when the cheapskates'
wiring rots through putting them in the dark.....(c;

Keep an eye out behind you! One of those tow guys may take a pot shot!!

I live so far out that we only have had one "Float By" sooting in
the last 15 years, and they were not shooting at me, just the neighbors
5 miles down the beach.........

You have to hate those boats with diesels when they do
a float by sooting
