Source of energy, Testatika

I am currently confused by the picture I posted myself about the ignition coil and need some hint in understanding. If you look on the right coil there is a text written "gemeinsamer Wicklungsanschluss". This means to me, that the thin and the thick wire are soldered together. 
Since when is an arrangement like that working? I've never seen a transformer like that. Do I interprete something wrong, or are the coils really soldered together at this point?

@gauschor: Yes, that is correct. Electrically, the primary and secondary are connected together at the "bottom" of their windings and this point is connected to the system ground. This is similar to the grounding of a sparkgap tesla coil, where the primary and secondary  may also be connected and grounded here, at the electrical "bottoms" of both coils.

Makes sense if you think about the car's wiring: the wires only are the positive for all circuits, the negative is the metal chassis and engine block. So the primary of the auto coil has its positive (Klemme 15) being interrupted by the points/condenser, and its negative (Klemme 1) going to chassis ground. The secondary has its high end going by a single wire to the spark plug, and the ground electrode of the spark plug goes to the engine block which is electrically connected back to the common ground. And the ignition coil makes this connection internally as well.

Damn...

@TK: thanks for confirming that. I need to work on my setup, because I only connected the coil with the many windings to the ground.

Auto ignition coils can work to 20-30 kV or so but at relatively low frequencies due to the core saturation.

I don't know if it will help at all, but here's a tiny Jacob's Ladder that's using an ignition coil for its HV output.

The same basic circuit, with a different output stage, can also be used to drive a CRT flyback transformer using a custom 10-turn primary instead of the flyback's own primary.

The Ignition coil version does use the low-point grounding together, but the flyback version does not. So... I don't know which way will work best for you.

I knew Prof. Stefan Marinov quite well. Unfortunately he committed suicide in the mid nineties. Marinov told me the
Methernita group said they would give him the secret of the Testatika if he joined the group and swore to keep the secret.
He also told me that they said it is not an overunity machine as this was impossible and but that it draws its energy from space. The small machine had to be aligned N-S to start but there was no similar constraint on the big machine.
Marinov also said  that Paul Baumann was a watch maker and early on was briefly in prison for some reason and employed in the workshop. At night when the lights were out, he always had a source of light to read by. We speculated on this and came to the conclusion the light was probably produced by luminous paint activated by radium bromide which was common practice for luminous clock and watch dials at that time and readily available for watch and clock dial painting.
I asked Marinov if the he thought the  testatika was powered by this radium bromide and he said he hoped not. 
here is an example of a possibly similar effect of radium on radio antenna
