I have a Heart Interface Freedom 25 in my boat with a remote that no longer provides me with AC power to my outlets. I had a lot of power coming into the boat for some reason (at least 150 volts according to my gauge) and discovered I lost AC power to outlets. Turned the unit off then on and power was restored but over a day or so degraded so that now there is no power regardless of what I do. A fan would cause me to lose power. Can you repair?
