The electronic transistor switchboard

In the electronic switchboard there is a powerful transistor which switches on and off current giving to the ignition coil (or to ignition coils). Thus, huge pressure cannot prevent work of sensitive electronics of the block of management. However the transistor submits a current not to that moment, in which gauge of the Hall (with 4 and 5-cylinder engines) or the gauge of the moment of ignition (models with 6-cylinder engines) deliver to model the impulses. The management block independently defines an ignition certain moment, giving that an inclusion/deenergizing impulse.
