5/71 240Z. Went to drive home late at night from the SnowBall Rally in April, discovered no headlights, neither high nor low beams. Headlights used to work, but now don't. Trying to figure out the issue before the MotherLode 400 Rally. My combo switch had been falling apart, suspected that was the problem. Jay Zinc refurbished my combo switch, tested it, but still no headlights. Pulled every single fuse I can find, including all the fuses in the aftermarket fuse block that Fitted Garage installed, they all have continuity. Found the headlight power connector, confirmed that both filaments in both stock headlights have continuity. No voltage detected at the mating connector, with the car running & headlight switch on. Seems like the problem must be somewhere between the combo switch and the headlamp connector. All other interior and exterior lights work. Suggestions would be appreciated. The precipitating event might be shown in this image, as snow melt caused this creek to overflow.
