See:  http://en.wikipedia.org/wiki/Galvanic_corrosion

As Gary said... Use Copper connectors.  I use all copper connectors,
and have no galvanic corrosion on my terminals.  Though oddly I do
have galvanic corrosion on the steel buckle of the cargo strap holding
down a couple of the batteries in front where we could not bolt down
the batteries.


> 2.  Is this related to the fact that it is the most positive terminal or the fact that the fuse holder seems to be made of galvinized plated metal?

Most likely.   I find that Water Miser caps on the batteries help keep
the vapors down, which can help with corrosion too.
