the output voltage seems ok; check the schematic - after impulse from magnetic sensor, thyristor Ty is conducting, and energy from capacitor C5 is discharged to ignition coil ZC. You have to be carefull, the ignition coil is not 12V, but 6V to work. You can order it from here: http://www.tatravintage.c...il-6v-tatra-603-t603.html
When you don´t have incorrect ignition coil, maybe C5 lost his capacitance, but it is quite rare failure (the original Tatra parts were designed with high quality).
Let us know, if this helped...
