Help! I have an 89 f150 that is starting to concern me. The fuel gauge stopped working fully about 2 months ago. Reads half when it's full and is out of gas and reads 1/4 tank. Now the alternator/battery gauge is not reading anything. I was driving home and the gauge went from "normal" to in the red in about 10 minutes. It stayed in the red and then when I stopped it and cranked it again the gauge needle is stuck all the way to the left. Truck still runs but the gauge is obviously bad. Any suggestions?
