Re: ground wires

The best advise I can give you is to find a competent tech and take your boat to him. <br /><br />The mercathode system is usually coupled to an isolator and once you introduce an AC curcuit the whole shooting match gets mega complicated.<br /><br />Green wires are grounding safety wires and (with the addition of shore power) usually connect to a galvanic isolator. As I said, it gets very complicated - too complicated for a computer screen diagnosis.<br /><br />Aldo
