It a quick question. I have never noticed it before but when I turn my headlights on my voltage will drop about 1 volt. I have never noticed it before. What could this be? My voltage seems a little high. On my auto meter gauge I can see that it is tight at 1 volt only when I turn the headlights on. I can turn the interior and the parking lights on with no change. It's when I turn on my headlights that I get the drop. Any help would be great.
