(DG) Which display is compatible with which Radome

[boardman74]

So I was able to get to the boat to remove the R20X that wasn't working. When I got home and test the unit works fine. Powers right up and goes thru any items I try.

So I am 99% sure I have an issue of power in the boat. So I need to sort that out.

Question is I cut the power cord about 24 inches from the unit to test at home. Now I need to splice it back. Red to red and black to black, obviously. Does anything need to be done with the wire mesh casing that surrounds the red/ black wires just inside the rubber outside casing? Or is just another layer of protection?
