I could ground to the battery, don't really have a reason as to why i didn't.
The factory fuse is 20A and the fuse that was in the harness is 20A.
At lunch i did a once over the harness and everything looked ok but there is a plastic cover on Fords/Lincolns that i need to remove to get a good look at everything, so when i get off i will pull that off and check again.
How can you tell if you have a bad ballast? On second thought though, i did try unplugging each light one at a time leaving the other plugged in and i got the same results so i don't think that's the case, unless they are both bad.
