I installed all new Raymarine electronics on my 05 SeaRay 270 Amberjack this spring...just got the 4KW HD digital radar dome in place and hooked up. However, the manual says to hook the green wire to a common ground. I don't see any other devices hooked to a common ground. Should there be? My old C70 had a ground screw on the back of the display. The diagram shows it going back to the batteries.
