Thanks for any help. I have a 65 Coronet and a 67 Barracuda. Both have dim dash lights. I Have installed new LED bulbs, new headlight switch, checked the bulk head dis-connect (cleaned) ran a ground wire from the dash to the - battery post, and checked the disconnect on the printed circuit board on the back of the dash. Bulbs are still dim. Led helped a bit, but still very dim. HELP.
What else can I do? I did this to one car the 67.
