The electric circuit of system of ignition is submitted in fig. 8-19. Since 1987 on a part of cars the contactless system of ignition (fig. 8-20) is installed. At this system a power-supply circuit of primary winding
coils of ignition is interrupted by the electronic switchboard 5. The operating impulses on the switchboard move from the contactless sensor located in the ignition sensor distributor.
Since 1986 the additional relay of ignition 7 (see fig. 8-19) type 113.3747-10 is installed.
