Does anyone know the route of the anchor lightg from the panel to ithe base of the mast? The boat was rewired by the prior owner who admitted to me that he did not change that wire. The anchor light does not work but I believe that the bulb is good and the mast is rewired but I don't want to step the mast this season so I am trying to determine if I can find the line and wire anew from the switch on the panel.
