The radar indicates the rain is past us for today but a deep low persistes to make life miserable for the next few days.  I spent today researching marine grounding systems and galvanic corrosion.  In addition to the discovery process and revamp of the alternator system, I have been wanting to install a galvanic isolator in the green wire AC ground system.  In order to do all this I have to insure that the boat’s current 120VAC neutral and green wire ground system is set up correctly.  I just have a sneaking hunch that the neutral and earth ground are tied together somewhere in those three or four busses that lurk behind the circuit breaker panel.  Since the boat is coming out for winter storage in the next few days this task becomes a winter project.
