I'm redoing a lot of old wiring
and wonder about the shielding on the 1622 radar
. The power supply cable has a 3 pin connector at the display so I assume 1 is for the shield wire.
manual says to ground the display (wing nut on back) to a bolt welded to the hull
. Won't do much good on a fibreglass hull
What should I do with the shield wire?
Should I ground the display to the water
My thru hulls are Trudesign so no ground to water
there, maybe raw water
