Andina has a site with a great description of stray current problems and galvanic isolators. It used to have a circuit diagram for a DIY project but it is no longer there. Did someone by any chance save the page as a file and thereby have that diagram? Regards. Larry

Did someone by any chance save the page as a file and >thereby have that diagram? www.archive.org is a great resource for this sort of question. It takes and saves snapshots of websites, so you can go back and find things that have otherwise long disappeared. The page you want is here: http://web.archive.org/web/20031219154039/yandina.com/galvanicIsolator.htm Also available on archive.org is great stuff from the now-defunct fuelpolishing.com website.
