Hi All,
We are moving forward in the purchase of this boat knowing there are a few gremlins we’ll have to deal with. What boat doesn’t have a few gremlins?
Our immediate concern is the Galvanic Isolator: It’s a Pro Mariner that appears to be original. With Shore power plugged in at the dock, the Galvanic Isolator self tested with an alarm for a Ground Fault. We swapped out the Twin 30A to Single 50A adaptor, and the isolator continued to show a fault. The surveyor indicated that it may be an issue with the marina’s power or could be a bad unit.
Several Questions: Where is the isolator located? Has this occurred to anyone? What should I be looking for? I see on a different thread there are directions on how to test the unit itself.
We will be transiting 190 miles of the Erie Canal and Hudson River within the next several weeks, and I plan on testing the unit at different shore power outlets along the way if I don’t get time to locate and test the unit. I do plan on resolving the situation as soon as I get to my home port.
Thanks for your advice and opinions
