The masthead wires are available at the steaming light. The C27 site had wiring diagrams up. I think they all share a common ground or something odd like that. The teak column in the cabin under the mast has a hollow in the middle, wires come up through that. I believe they run under the sole to that point and aren't accessible there. At the deck-mast point there is a plug connection for the wires, I think that was factory standard.
I agree with Bob it's probably a problem at one of the fixtures (steaming or masthead).
