As
@Davidasailor26 said, you might find someone who has a basic schematic, but aware that undoubtedly,it has been changed and bastardized by a PO.
i was working on my DC wiring yesterday. For some reason a PO wired the refrigerator with a 12-volt cig lighter outlet in the V berth and 2 other outlets were wired in with the AP…
So, I was abLe to install a new breaker, move the 3 outlets to their own breaker and separate my AP and refrigerator circuits.
The point is, I don’t think the boat had those cig lighter outlets when new, so they would not have been on the electrical plan at all. In fact, I just checked it and no refrigeration listed either…
Good luck…
