Electrical structure:

Printed circuit board with discrete components (condensers, resistances etc.), microchip and ion current evaluation filter.

Oscillating circuit with control and regulating circuit for the ignition output stages.

Switching-over between the 180 volt main voltage and the auxiliary voltage (about 23 volts).

There are seals in the spark plug socket (1) to protect the ignition coils.

NOTES The seals (1) should be replaced every time the ignition coil is removed and installed again.

IMPORTANT The spark plug connectors cannot be removed.
