Possibly UV damage? There are a lot of plastics that don't do well in
sunlight because of that.




In the shade under the bimini. No sunlight direct.

The ONLY place where the plastic disintegrated is BETWEEN the +12VDC and
ground pins. The rest of the plug was untouched out of that path between
ONLY those metal pins, a track about 1/16" wide. The dead pins and the
plastic behind the exposed power pins was untouched by the devastation. It
points directly to 12V electrolysis between those pins.

Garmin needs different thermoplastic in their plug maker machine.
