I'm having the same problem, hit a pothole yesterday and lost all electrical systems, minus ignition and fuel. No clock, radio, gauges, headlamps, turn signals, brake lights...everything, but the engine still runs fine. I'm guessing a relay or the ignition switch, but haven't dug into it that far yet. About a year ago I lost one low beam and both high beams, they were only getting 1.5v, I never figured that one out, otherwise I haven't experienced any other electrical problems. Any other suggestions?
