This has me stumped. Been searching this forum for suggestions but can't find any. My Astro Headlights don't work. Tried a known good switch and swapped mine into the other vehicle, works fine. Bulbs are fine, relays fine and fuses fine. I have all parking lamps turn signals etc, just no headlamp operation at all. When I ground my test light, I get voltage at all of the connectors on the headlamp hardshells...I suppose one of each of the 2 wires going to each lamp should be a ground and it doesn't appear to get ground anywhere. Anybody have any suggestions?
