Dog, Thanks. I too have this problem and will find this helpful. Three questions:
1. I have a memory circuit for the stereo, which is switched so I can stop the battery drain during long periods of non-use. I'll switch it off before doing the leak test. I know this isn't a "leak", but does this minimal powered ciircuit contribute to the zinc corrosion?
If there isn't a ground leak to the water...then it shouldn't matter. BTW, I would highly recommend that you physically disconnect all the wires for the DC ground leak testing...
2. I have a bilge pump with a float switch. As long as it's not actively pumping, this shouldn't affect the leak test, should it? In your preliminary diagnosis test, I assume you are referring to bilge pumps with electronic switches that draw current as part of the sense circuitry. A float switched bilge pump shouldn't have to be disabled before the leak test, correct?
3. Your instructions tell how deterine if you have a leak. How do you isolate it if you determine you have one?
I don't give instructions for isolating or fixing a DC ground leak, because they're very specific to each individual case.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
