Rubrail and touch-ups

Well, it never ends, but it's important to celebrate the progress! On Saturday I did some touch-ups on the boat's paint job and installed a new rubrail. I should have taken some pictures, but I'd forgotten the camera. The rubrail is the same as the one on Ann Bonnie, and it looks great. The paint job is at this point complete, unless I go crazy later and decide to add another coat. I also looked into the electrical issues: the running lights, which are the most important thing, work fine, but the cabin lights and , I suspect, the mast light, aren't coming on. I isolated the problem to a voltage drop across a couple conduits connecting things to each other on my fuse box. Problem is, I can't be bothered to make a temporary fix of this -- I don't have the appropriate end fittings, and, ultimately, am I supposed to be rebuilding my electrics annually?!
