Top Down logistics [RE-wrenches]

[Brad Bassett]

Mo,

You may want to consider heat shrink wrapping the MC connections out on 
the island. There are two issues; one is sea gulls, and possibly other 
birds, that like to pull at the wiring, and corrosion. After the gulls 
have pulled the connection apart the corrosion takes over. Even if the 
wiring is well fastened, the gulls are pretty crafty and amazingly 
persistant. The USE-2 XLP wire seems to stand up pretty well. If you are 
making your own MC connections make sure there is adequate wire 
insulation in contact with the MC boot so there won't be corrosion 
getting through at that point. In other words, don't strip the wire 
farther back than necessary to crimp it well.

Have fun in the sun!
