I will be looking at a Morgan O/I 28' in a few short day. My wife and I are looking to live on the boat; however, the owner says that there are some DC electrical issues. I have only had limited interaction with the current owner and the description of the issue(s) are vague. With the diagrams posted above would it be a simple thing to rewire the DC system on this boat, and are there any other things I should be concerned about when looking at the boat for the first time? Call me a novice, but we have a dream.
