I don't have my old books here.
You could try searching for information about "Earth Lamps" in Marine Electrical literature, Its only a small step then to adapt to measure Meg ohms (less than 1 Meg Ohm is hot). Earth leakage detection equipment are found on every vessel subject to classification society rules. These are used on every separate circuit (all AC and DC).It would not be difficult to create a earth lamp circuit that would be useful in your search for a faulty circuit. Many times I have searched for faulty circuits in ships (as Marine Engineer) usual suspects are Lighting circuits that get wet by Salt water, heating elements especially in galley ranges that get fresh water washed by enthusiastic cooks, also found in domestic fridge. Searching is done by isolating circuits one at a time until you see the fault disappear.
