Is it OK to have a 12v electrical
connection outside the boat
and exposed to weather
if it is protected by heat shrink tubing?
SO 40.3 has the red and green nav lights mounted to brackets attached to the pulpit. The nav lights are separate lights not combined into one unit. I need to replace them for a few reasons and want to upgrade to Hella NaviLED PRO navigation
lamps. These have a long (2.5 m?) cable that comes out the back to connect to the boat’s wiring
- very similar to what I have there now. The cable on each of the existing lights is routed along and zip tied to the horizontal pulpit railing and then enters the vertical portion of the pulpit through a grommet.
The problem is, there does not appear to be any slack where I can pull the existing cable out, connect the new lights and then tuck the new connection back into the pulpit rail. Will the electric
connection be sufficiently protected if I cut the existing cable, connect the individual wires in the two cables
with heat shrink butt connectors and then cover the whole connection including both butt connectors with heat shrink? I would zip tie that to the rail like the original but it would be exposed to weather
and not buried in the rail. The option is to trace and replace the wiring
back into the interior
of the boat
, which is not a terrible idea but will take more time now than I have available right now.
