I recently bought a 93 f250.
Everything runs and works great but a few electrical things.
My fuel gauge always reads empty. When I turn the truck off the needle comes off of E just a little. Also my speedometer needle moves around kinda crazy while driving. I pulled the dash off today and when I take the tank switch off the fuel gauge goes way past full. I took the instrument cluster apart and am trying to clean it up now to see if it a bad connection somewhere. Any help would be great. Thanks guys
