DoctorBill Posted February 9, 2010 Share Posted February 9, 2010 I got fed up with my insane and completely bonkers '95 XEV6 4x4 Pathfinder's Tachometer ! So I bought a nice looking and inexpensive EQUUS "6088" Tachometer at Shucks (O'Reilly) for $30. http://www.oreillyauto.com/site/c/detail/EQU0/6088.oap?keyword=6088 Looks nice and it is made in Taiwan - not in Mainland CHINA !! Ha! Here in RED is what I don't follow.... and the rest of the destructions... Now...why do you connect the sensor wire to the negative (GROUND) side of the coil ?! Wouldn't you put it on the positive side where the signal is coming into the coil ? I will "try" to mount this in front of the normal Tach and will disconnect the signal wire tot he old one - just to keep it from doing it's insane movements. Opinions - and don't tell me to throw it out and spend $100 on a better one ! Suggestions - a better place to mount it ? DoctorBill Link to comment Share on other sites More sharing options...
BenStoked Posted February 9, 2010 Share Posted February 9, 2010 If I have read the FSM correctly, most of the engine electronics are negative signal fed (injectors get constant +12v, are pulsed by ECU "sending" -12v signal, for example). I believe it's the same for coil. Link to comment Share on other sites More sharing options...
Precise1 Posted February 9, 2010 Share Posted February 9, 2010 Why didn't you just replace the factory one with a functioning unit out of a part out vehicle?? B Link to comment Share on other sites More sharing options...
