Ford Focus>> Ignition system>> Work with ignition system>> Measurement of resistance of the coil of ignition by means of a multimeter
Check resistance of primary winding of the coil of ignition by means of a multimeter transferred to provision of an ohmmeter for what execute the following:
- switch off ignition;
- remove wires of a high voltage from the ignition module;
- remove the multicontact socket;

Fig. 213. Check of resistance of primary winding of coils of ignition: 1, 2, 3 — contact sockets



- check resistance of primary winding of the coil, for this purpose an ohmmeter one after another attach to plugs 1 and 2, and also 3 and 2 (fig. 213) . Both indications of measurement should be in limits 0,4 — 0,6 Ohm. If the measured size does not correspond to this value, it is necessary to replace the module of ignition.
