I just upgraded my boat to have a refrigerated icebox, but I have a problem. The refrigerator switch on the electrical panel was unused before. When I went to hook up the wires I get no juice. I used a tester and isolated it to a bad switch (Carling brand). My problem is where do I get a new switch? I searched the Carling website and found nothing. There is no part number on the switch so that makes it more difficult. Does anyone now where I can get a new switch that will fit my panel? Rgds, Todd
