The conduit makes sense but I dont see any signs of it (with the mast up). Over thirty years its no telling what is or isnt there that should be there. I will check the grounding with what I can get at. The masts should be down comment is interesting. This will be my first winter in the slip with a non-trailerable boat, but this is Nashville and as best as I can tell all the boats stay in the slips all winter so the masts dont come down whether they should or not. We really dont seem to have the facilities to pull the boats out for the winter and put them on stands.

All wiring must be routed thru it to avoid fouling with the internal halyards. On my boat, an '84 27SR, the connection to the main harness is at the base of the mast, and is accessible by removing the halyard blocks at the base of the mast. You can use a test lamp available at any auto parts store to test the appropriate connection to see if it is hot when the lamp is turned on. The lamp, of course, will have to be attached to a long wire running to the electrical system ground bus or a battery ground terminal. A long pair of battery jumper cables serves this purpose. If none of your lights are working, check the ground connection by connecting a cable to a + connection on a battery, and touch the tester to the ground connection from inside the mast. If it lights, your harness is grounded. I would add that, if wiring needs replacing, it would be best to replace all of it over winter when the mast is down. Masts SHOULD be down over winter.
