I have a plate Alloy Boat
All my accessory wiring earths and outboard earth are connected to a grounding bolt through the hull. Battery Earths as well.
(As per Quintrex std Wiring.) There is no electrolysis or stray currents etc
I have an existing system 3 x Lowrance live units, Radar, Auto pilot etc all working fine no issues.
I'm fitting a TZ3 12 touch system. DFF3D and Scx20.
Should I be connecting the grounding screws (TZ3 and DFF3D) to the hull of the boat as well?..
Or try it first without them grounded.
