My 1974 boat's DC wiring was all done with plain
copper wires. The wires for the overhead 12 volt
lights were imbedded in the fiberglass of the
underside of the deck, so I know the manufacturer
is the guilty party. When I bought the boat in
1996 all the 12 volt lights worked. Within 2 years
I had to replace the light fixtures in both the
head and the galley, the bulb contacts were
corroded beyond repair.
After cutting the already-spliced at least once
wires, leaving as much length as possible I
started to strip the wires to attach the new
fixture wires (ALSO not tinned!). The wire was
green. I cut and stripped until I finally found
bright copper. This left me with just enough wire
to do the crimping job and mount the new fixtures.
I covered all wire with hot-glue heat shrink
tubing to try to prevent further corrosion.
The only problem is that now, just a few years
later I have no light in the head, and the galley
light's switch is so intermittent that I leave it
in the ON position and use the breaker to turn the
12 volt lights on and off.
Some day I hope to install new wiring and a
separate breaker for each fixture. I promise you
all I will use fixtures with no switches, tinned
wires everywhere, and gold plated crimp
connectors!
After I win the lottery of course...
