Re: I really hate electrical gremlins... gauge lights mystery

Use a 12 volt tester and with a good ground carefully check both sides of one of the bulbs while it is still plugged into your dash. I would bet one side will be bright on your tester and on the other side of the bulb will be dim (bad ground ) I am sure it is a bad ground at the 1/4 inch screw on the printed circuit. That one screw grounds 3 of the 4 dash lights AND both of your turn signal lights on the one circuit on your printed circuit. I had to play with mine to get it to work. Also mine was a new printed circuit from LMC
