Hey All, Installed the Petronix Ignition Module and 3.0 Ohm Blaster Coil from Motorsport Auto on my 70 240. Per instructions for the 3 ohm coil, the ballast resistor was eliminated and leads connected together. The car starts and runs better than before with points but noticed that above 1500 RPM the Tach no longer works?? Has anyone had a similar experience and resolution?       Sent from my iPhone using Classic Zcar Club mobile
