Alrighty then. I have an '02 6th gen. No lo beams despite 12V at the connector. H4 bulb replacement yielded bupkis. Not the starter switch or the relay. Hi beams work fine. There's only about 10V at the socket connector until I fire the engine, then I get 12V, but headlights don't turn on. I checked the ground at the battery and it's good. Leads me to believe it's a lack of current, but I have no clue as to where to look next. Any ideas?
