I put this in electrical section with no reply so I am trying here. 2002 Sea Ray 220 Sundeck. A couple of weeks ago a few of the lights on the switchpad did not light up even though the blower, bilge pump and interior lights worked. Over the weekend the lights and all accessories connected to the pad stopped working and none of the lights light up and the horn does not work. The plug in the back is connected and all fuses are good. Where do these wires go to? Someone said there is a computer it is connected to. Thank you. RR
