Device is supplied by 12 V of a car. The voltage of 250V to the photo-lamp is making by converter. Flashing impulse is coming from sparking-plug of first cylinder (*** You can see this wire in the center of bottom of picture 1***).
Transformer is made on magnetic iron core of "m" or "ITI" type with dimensions 16x20 (*** I do not know how to translate type of iron core ***).
Coil 1 and 3 are winded together by copper wire of 0.5 mm diameter - they have 21 turns each.
Coil 2 has 7 turns of 0.15 mm wire and it is winded in two parts. Beginning of second part is end of the first - these parts are winded together. (*** It is not comprehensible if there are 7 turns in every half or in two halfs together ***)
Coil 4 has 500 turns of 0.2 mm wire.
C2 & C3 with paper dielectric have 400 V max voltage.
R1 - wire type.
To use this device, link flash wire to sparking-plug of first cylinder (with non working engine!!!), then connect supply to 12 V source of a car. Then start your engine and makes your adjustments .
Sorry for possible mistakes on my ugly translation. Ask me questions - I will try to explain.
