Re: ICOM M-710 Lights up my electrical panel
Maybe try disconnecting different ground components like s.s. rails and thru-hulls one by one to see if maybe one is the cause. Do you have a central thru-hull bronze sintered ground plate with the copper foil attached? I ran the copper foil stem to stern, attached to everything, stanchions, bronze thru-hulls, water heater, pushpits, etc. including the ground plate which grounds the engine and everything else. It could be your ground plane is not effective enough? That's the thing that would seem a potential problem with the small (kiss) ground plane/counterpoise units.
