First you need to verify that the Diesel tach is usable with and
correctly calibrated for the signal from the coil primary.  The
diesels get their tach signal from the W terminal of the alternator
which I suspect is much higher frequency and much lower voltage than
you'll get from the coil.  The coil signal probably peaks around 100 volts.
