    which wire for tach???

    I've got a 1999 Genesis that the tach is not functioning on. Everything else on the MFI is working. Which color wire from the CDI controls the tach??? Any help appreciated.

    I have no idea how the Geni display works but could it be you're set to digital display?
    Try pressing the DISPLAY mode button ND HOLD IT UNTIL IT DISPLAYS PEAK rpm's, see if that works.

    Yellow wire is the tachometer signal, but the signal doesn't come from the CDI. It comes from the stator coil in the flywheel.

    Yellow wire is also used to control battery charging, so it is also connected to the LR voltage regulator. Check that you are getting 14 volts at the battery when the engine is running.

    The other end of the stator coil from the Yellow is a Red/Purple wire to the stator. Make sure that is also connected properly.
