[C320-list] Depth Sensor

[McCullough, Kirk]

On a slightly different subject:

Has anyone ever changed the depth sounder sensor? I am getting a zero
depth reading on the display at the helm. The speed indicator works just
fine, so I am thinking it must be the sensor. I don't have any
information on how to change this unit out.

Subject: [C320-list] Knot Meter Sender Replacement

I'm replacing the Raymarine knot meter sender (thru-hull unit with
paddle
wheel) as it's defective. I've tested with a new sender by spinning the
wheel and the display showed "speed" just to make sure it is the sender
that's at fault. Due to the five female spade connectors on the
instrument
end of the long cable that comes with the sender I'm having difficulty
removing the old sender cable down through the port pedestal guard tube
to
the aft cabin ceiling below.  There is a cover for the steering pulleys
with
about 12 screws which I removed.  This pedestal guard tube is so packed
as
there are many other cables for other instruments in the port side of
the
guard as well as in the starboard side.  As I have to attach a thin
nylon
fish line to the end of this with electrical tape all over the spade
connectors, I feel there is no way to pull them past the other cables
(without it breaking apart or damaging the other cables.  The only way
this
could be pulled in my mind is: disconnecting all of cables to the
instruments and pulling them all out as at one go and then pulling them
all
back, minus the old cable, adding the replacement cable.  That would be
a
lot of hassle.  Can anyone see a problem if I cut the cable (say under
the
port settee) and solder the fire wires in this cable, using heat shrink
on
each wire and then a larger heat shrink on the cable jacket?  It's
pretty
dry there, especially if I tyrap it high up.
