I’m following this topic with interest. First, the seacocks need to be bonded and protected by the sacrificial anode. I’m a new Amel owner and learning about its electrical system right now. I’m a retired electrical contractor and engineer and I will say that I’ve not been a fan of floating ground systems. However, Matt Salatino has it right... if it’s not broke.... I’m not about to change anything until I have a full understanding of the systems.
