For electronic ignition systems, the operating voltage is up to 40,000 V under adverse conditions, for example, in the presence of moisture in the engine compartment, high voltage can break through insulation and touching a high-voltage wire can cause electric shock.
To prevent electrical injury and / or damage to parts of the electronic ignition system, when working with the electronic ignition system, pay attention to the following:
Carry out an engine wash only when the engine is not running.
Disconnect both wires from the battery when performing electric welding on a vehicle.
Do not disconnect the wires from the battery, alternator and starter while the engine is running.
When measuring compression, be sure to remove the main relay of the DME system so that there are no ignition pulses.
Disconnect the wires of the ignition system only when the ignition is off.
Connecting and disconnecting instrument wires (tachometer, ignition tester) only do it with the ignition off.
Secondary (high voltage) the ignition system circuit must have a load with a resistance of at least 4 kOhm. The spark plug plug must be connected.
Never start the engine with the wire disconnected from terminal 4 of the ignition coil.
To terminal 1 (-) ignition coils, an interference suppression capacitor or test light must not be connected.
Terminal 1 of the ignition coil must not be connected to ground or battery positive. When installing an anti-theft system, do not use the wire going to terminal 1 to block the engine from starting.
When heated to a temperature of more than 80°C (e.g. when cleaning the engine with steam or when painting a car) the engine must not be started immediately after the end of heating.
