Short circuit

Friends,
1989 Westy full camper. Sixth in my series and a keeper.
Driving along making hot water for coffee with an immersion heater in the cig. lighter socket, a fuse popped. No. 3, 15 Amp: lighter, radio, vanity mirror, horn, dome lights and cabin light. With everything off, a new fuse popped immediately. The water heater may have been an overload (never before, though) but now I have a direct short to ground. The lighter socket looks fine. I'm at a loss on how to troubleshoot this without a full dash and other disassembly. Maybe the horn wire is frayed? What else might it be?
