So, why is it that the original Marelli coils of that era did just fine at the proper 3 ohm resistance, while Dynatek recommends 5 ohms type coils?
One of my 3-Ohm Dyna coils cracked open some years ago, and now I have the 5-ohms type, but they actually measure at 5.8 OHms. What is the optimum primary resistance?
