REf this subject, I moor in a fresh water marina on Lake Superior and am wondering if there is an easy way to test for this problem of stray current.  If anyone can describe a relatively simple method to do this kind of test please post it up.   Gary Hagstrom Iron River, Wisconsin

You get a silver/silver chloride cell like this https://boatzincs.com/corrosion-reference-electrode-specs.html and connect it to your DMM. One side to ground and the cell in the water. Even 10 milliamps can paralyze you and cause drowning. Just because you test one minute and find nothing and jump in the marina waters the next minute does not mean that somebody nearby has not energized an AC circuit with a fault the second you were done. Just stay out of freshwater marina waters (at least 50 yards), and don't dive off your own boat with ac power energized. There is a thing on Amazon called shockalarm you could look into.

The reference cell you’re talking about tests for the potential for galvanic corrosion, not AC current leakage. Just FYI. Brent
