Testing the primary and the secondary windings on coil on plugs. Ford Focus 2.3 Litre. The specs in the manual says primary should be 0.4 to 0.6 Ohms. And the secondary windings should be 10,500 to 16,500 Ohms.I checked it today and the primary ran from 0.13 to 0.14 Ohms for the primarys. The secondary was 5500 ohms. Does anybody have any insight of what it should be and what I came up with is any good.I would appreciate it.
