That's easy to answer. There are several "groups" of 12v neg terminals, created by electrically joining individual terminals using a piece of metal. Some groups have the continuity with the 120v ground. Some don't. And sorry, there is no way I'm putting down my multi-meter. It is the best tool I have to understand how my boat is currently wired. You can't get that from a book. Once I understand how the system is currently wired, THEN the books will be used to help me improve what's there.
