Hello, starting up a new project, some parts new some old, I want to do my due diligence putting things back together to weed out issues. Could someone tell me the primary resistance and the secondary. Would the secondary reading be the same on both boots (first dodge?). Also is there a way I can check injector pulse, dont care to know how much, Just like to know if they are pulsing.
Thanks

Noid lights are a quick/easy way to verify injector pulse. As for the coils, its been awhile since I've owned a Hemi coil, but the Primary winding are typically very low 1 or 2 ohms. The secondary is often around 8,000 ohms to mid-teens thousands (maybe as high as 14,000 ohms). the good news with the coils is there are 7 other coils to compare the readings too - they need to all match pretty closely.
