Check up resistance of a primary winding of the coil of ignition by means of a multimeter translated in position of an ohmmeter for what execute the following:
- Switch off ignition;
- Remove wires of a high voltage from the ignition module;
- Remove a multicontact socket;
Fig. 213. Check of resistance of a primary winding of coils of ignition: 1, 2, 3 — contact sockets
- Check up resistance of a 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 ignition module.
