OK, my first post to this forum and probably many more. I recently purchased a 67 ss396 L34 and did not check the headlights. When I turn on the lights the fuel gauge turns off, right blinker light comes on, and alternator light glows dimly. I think this is a ground problem or could be the switch. I haven't tried to find it yet but would like to drive at night some time. Any thoughts how to start on this?
