My gages stopped working one by one and then only worked intermittinly. I have take the instrument panel out and checked the circuit board and all the inline fuses as well as the fuses in the fuse block. They all checked out good. I cleaned everything and did a continuity test and it shows the circuit is good. All of my insturment panel lights and direcinals work. But none of my gages do. I have a wiring scchematic for the truck and checked all the lines for fuses etc and everything seems to be in good order. Chiltons manual says when all the gages done't work it's a blown fuse. But I cant find one. Can anyone give me any ideas what the problem might be. I also put a new low voltage regulator on the back ot the instrument panel which is used for the gages and this didn't do any good. I am sure it is something simple , but I can't find it. By the way all the gages did not go out at once.
