The light behind my fuel gauge seems to be bright and shiny, then just goes away whenever it feels like it.Also when I first got the truck the voltage meter worked fine, now it shows nothing. The two generator lights that come on when you start the truck, one of them stays on until I actually start driving. Any common problems you guys see here? Also where is the best place to run the two power cables for a radio? Any help is much appreciated, brand new to the diesel scene, and I have always been terrible at wiring...
