Hello dear Ford municipality, I need a little help and hope to find this one here. The following problem: On my Ranger Everest, the speed pointer spins, it stays at about 1000 rpm with a slight up and down. 1000 rpm therefore, because the idle could not really be adjusted. As soon as you give gas, it drops off to zero, and then to go back to about 1000 rpm. I can exclude the combination instrument, because a construction equal was used for testing, with the same result. I think, first of all, the sensor, perhaps someone knows where this seat? Belt disc how much is described, however, a dead end. Fly disc at least from the outside is not visible. According to my documentation, there is a sensor on the switching gear that is specified as a sensor tachometer. However, I do not know if this could be related to the speedometer. Question who knows where the sensor for the speedometer could be installed, Eventual diesel pump depending on the position of the gas train? Is there a fuse for this?
