Ian 0 Report post Posted May 13, 2009 Hi, This is potentially dangerous. If you are unsure about what to do, see an electrician This condition arises when the active and neutral wires are transposed. Assuming that it worked correctly before, it shouldn't be anything on your boat's wiring. So, what has changed recently? Have you changed the lead from the power outlet to your boat? Have you added an extension lead? Have you changed your location where the boat is kept? I would work backwards, checking leads and the power pole for correct polarity Remember, 110v can kill - if you are unsure about what to do, see an electrician. Depending on what state / country you live in, it maybe illegal for you to change or modify 110V wiring If it worked correctly before - Share this post Link to post Share on other sites
