    Tach Sensor testing???

    Thanks so much for your help here, I really appreciate it!!! I have actually never been able to get a voltage reading from the tach sensor itself, which may be part of the issue which im checking out now. However I was originally trying to get someone to check resistance to ground from NOT the...

    Tach Sensor testing???

    Any chance someone could verify the resistance of the tach wiring I posted above? Any help would sure help make buying a new part a lot easier.

    Tach Sensor testing???

    The computer was actually new to me too. Can anyone verify the resistance to ground readings from the tach sensor wiring (not including the sensor). I get little to no resistance on either terminal to ground. Is this accurate? I don't see how both can go to ground and that is why I am led to...

    Tach Sensor testing???

    Well I made it through the testing procedures from the pages that you posted on here. I am thinking it is the computer that is the issue. I am wondering how common this is or if there is anymore test's on the computer itself to verify. My other question is when I check for resistance from the...

    Tach Sensor testing???

    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...
