[nas t eh]

Got the tach working. I have a pertronix 3 and was worried about connecting the tach lead to the neg on the coil. I had incorrect info that the tach could be damaged by the multi spark feature.
But that is not true and in my cars case I didn’t need to add a resistor that is sometimes required for correct function of the tach.

Now I get too see how long the Pertronix functions before I get stranded like so many other have.
