Hi Guys, has anyone got any tips on how I can make my tachometer show the right revs now that I have fitted and electronic distributor? It reads really high now. I have heard that you need to put a resistor in the circuit somewhere or maybe run the feed wire from somewhere else. If anyone has done this before and cured the problem then a workable fix would be greatly appreciated

Install a Spiyda conversion: https://www.spiyda.com/smiths-rvi-rvc-conversion-external.html

This allows you to feed the coil directly from any switched circuit, eliminating a long chain of failure points.

The one you really want is this one, but for some reason I didn't see it in there web shop: "RVI-RVC conversion board"

Shoot them an email and ask.
