Hey folks. Went out for an evening fishing trip late yesterday afternoon. At dusk, I attempted to turn on my navigation lights and they did not work. I then started to turn on switches to the bilge, interior lights, and horn, none of them worked. My gauges all appeared to be working, but the backlighting for the gauges did not work. Note: Engine fired right up and continued to run as it should, just now power to the rocker switches on the panel. Any ideas or first steps I should take to diagnose the problem? Any input or advice is appreciated.
