We were up hunting today and doing a little 4x4n' and after checking a clear cut, when I started the truck back up all the gauges stopped working. There were dash lights, blinkers, headlights, etc. worked just fine but the Speed Odo, Tach, Gas, Temp, Battery, all needles just fell to the bottom and would not function. This must be a fuse or relay but which one. I checked the book and pulled the fuses that were labeled that made since but they were all fine! Any Suggestions to start with?
