Fuel guage is now INOP after removing wires from sender.? I was doing the big wash in my 40 today and after putting back the cover to tha gas tank I drove it into the garage and now the fuel guage is INOP......I unscrewed the ground and pull the wire from the sending unit. did I ground it by mistake and blow something?? I checked all fuses and all are good. I have a pulse at the sending unit with a test light. What did I do or miss???
