My tachometer only works a portion of the time, so I have installed a new tach sensor and still have the same results. I have since tested the new tach sensor with the ohm check and get the 2500 ohm range as I have read it should be, but I cannot get the correct voltage reading from the leads with the engine on. I actually went and bought a second tach sensor thinking I possible had a faulty one and I am getting the same exact readings.
Is there any chance the voltage test isn't a truly accurate test and the tachometer reading issue could be further down the wiring or into the instrument cluster?
