Hi,
I suspect a stray voltage problem on my sailboat because I have seen the coating on my keel bubble off, exposing the lead in several places.
In tracking this down I am at the DC bonding system and I have read just about everything I can find on the subject. I refer to this link.

I isolated a problem to my VHF radio - the antenna has continuity with the mast, and therefore is bridging the DC bonding system from the mast to keel and also into the DC Battery negative. So potentially this could allow stray current into the DC bonding wires?
If I have a DC bonding system should it be connected to the engine negative AND the DC GND Buss bar OR just in ONE place at the DC GND Buss bar ?
How about if I follow recommendations to isolate my Spartan bronze seacocks and not bond, but to keep my lightning from mast to keel, should the lightning end there at the keel or have continuity to the DC GND Buss bar AND/OR engine to zinc ?
Thanks for any help on this
