CORROSION on a boat: Stray Current or Galvanic? | Ask The Expert with NIGEL CALDER

[@blackquintet]

I have a galvanic isolator on my boat, and I wondered whether it was fail safe. I asked the company making the product, and they said that the product used two set of diodes, and if one failed, the second would insure it continues working. I my opinion, this means that the product isn't fail safe, since the second set of diodes might also fail, living the circuit open. Is that a sensible guess?

Can you recommend an experienced electrician to test my boat in the St Augustine area? So hard to find someone with this experience.
