While motoring from Martha's Vineyard back to Cape Cod today, the green light on the switch panel came on ...it's labeled "service on". I don't have my owner's manual with we so I'm not sure what this light signifies. About an hour later, it went out on it's own. Because it's green in color, I wasn't terribly concerned. Anyone know the meaning of this light which occupies the bottom left switch position on the panel?
