09 k-Ohms. 35 a while later). 2 ohms, secondary around 8,000–12,000 ohms. May 21, 2020 · Somewhere in the study of ignition science, many of us come away with the idea that secondary ignition voltage, as expressed in kilovolts (kV), is the end-all, be-all of engine performance. Aug 18, 2019 · It is difficult for the home mechanic to fully diagnose whether an ignition coil is good or not, as a full test would involve four tests: Visual inspection. Generally, the primary resistance is very low, typically less than 1 Ohm, while the secondary resistance is much higher, usually in the kilo-Ohm range (e. 7 ohms, secondary around 4. 5 ohms; secondary around 6,000–12,000 ohms. Units with high-temp epoxy potting or ceramic fillers resist internal breakdown under sustained load. May 29, 2020 · Coil output is a factor of its turns ratio, primary resistance, and input voltage—assuming it has enough time to fully “recharge” between firing impulses.
