The system is simple and reliable. The main element is impulses generator. It bases on LM555(NE555) and generates a signal for transistor's T1 base, which then closes the circuit of the coil mass. The result is a simple interrupter.
The coil in this case is a coil from Fiat 126p.
It generates a high voltage of several kilovolts. The frequency of the output voltage is identical to the factory designs, what is 60 pulses per minute.
Operating frequency depends on the capacity of the condenser 10uF.
The plate based on the scheme was designed in KiCAD.
Below there are some photos:
Inside of the housing was flooded in silicone mass to avoid weather conditions.
