Dave,
Very good question. I’m no expert but here is my understanding and my solution.
Since you do not have an RF ground, you can get by with grounding the shield
wire to the battery ground. In principle, you should not use the same negative
wire as used for supplying power. The reason is t
Dave — tie the shield to the negative power wire at the power supply lead to
the plotter. I’m sure there’s no RF grounding system on most of our boats; you
start seeing it on larger vessels or those with SSB installations.

This is not exactly the case.
Keep in mind that a lighting generates a current in thousands of A. That high
current generates magnetic field around it. In turn this magnetic field
generates current in any conductor in
On my 1980 version, I assume the 'grounding' system is original. There is a
cast metal box which the mast sits in and which in turn sits on the big oak
block. That box has a battery cable bolted to it which is attached to a keel
bolt. Hope it works.

I’ve heard in the past of this being done, but using chain. Does anyone know
