Low beam not working

My low beams are not turning on and my high beams come on when I pull back and not push forward. I saw somewhere on this site where someone ran a new ground wire to bulb. I'm not sure how to do this. Can someone help please!

 

See post #11. Sounds like a ground wire may have solved this for others.

That was the same post I saw earlier but was confused on which head light post to attach wire.

 

Since our headlights are switched ground through the headlight switch .

The switch controls which filament is energized low or High .

I am real curious just where one attaches a ground wire that does not have the light on till it is disconnected?
