congrats on the recent summerization... its good to see everyone else getting their boats ready... i am getting tired of everyone sitting on the dock... we need to get the boats spiffed up and get them out of the slips....
there are some "salon indirect" lights that fail to illuminate when the switch is turned on.... i checked the bulbs in another socket on a different circuit and they work. I checked the control panel for everything and it is all turned on.... is there inline fuses or something silly like that on these types of systems? or do you think when some work was done they got cut?
If there is more then one light not working I would start at the switch panel and look for fuses, could be a panel fuse, or an inline fuse. Maybe it shorted out with the engine trouble you had.
Although remote at best it could be that a wire got cut during previous work. The only way to know is do your best to trace the wire from panel to light.
My first step would be to ensure that the panel switch itself has power, do any lights on this switch work? If not could be a bad switch.
Good luck.
