While the engine is running or the ignition system is on, do not turn off or touch the wires of the ignition system.
All wires of the ignition system, as well as measuring devices, can only be connected and disconnected when the ignition is off.
If the motor is to be energized without the need to start it (e.g. to measure compression), it is necessary to disconnect the high voltage wire from the ignition distributor and close it to «mass». It can be increased if necessary (lengthen).
Starting the engine using a starting device should be avoided, as not all devices are equal. If this device is used, then the start should not exceed one minute, and the voltage should not exceed 16.5 V.
During repair work, the battery must be disconnected.
A car with a faulty ignition system cannot move on its own, it must be towed by first disconnecting the connector in the switch or disconnecting the wire from clamp 1 of the ignition coil.
Capacitors and test lamps must not be connected to connector 1 of the ignition coil.
When washing the engine, the ignition must be turned off.
It is impossible to replace the ignition distributor slider with a slider with a different marking.
High voltage wires and spark plug caps should only be branded.
It is not allowed to replace the ignition coil with a coil of a different type.
The ignition system generates an ignition spark for each cylinder at the right time. It ignites the sucked-in air-fuel mixture. In the ignition coil, the voltage of 12 volts of the battery is converted into a high voltage of 25,000-30,000 V.
The ignition system contains:
- ignition distributor with an interrupter or an inductive sensor in a transistor ignition system;
- ignition coil;
- spark plug;
- electronic switching unit of the ignition system (ТZH, VEZ systems).
