This is measuring what it is happening at the "power coil".

First readings using the oscilloscope:

It seems the classical format of the pulses, plus one artifact !

 

Noticed that single pulse between the "h" pulses.

Do not know what it is but after some small moves at the potentiometer was able to remove that
single spike:



And after that i could "feel" that the system is more "happy".

Also the speed at the wheel increases, but did not yet verify changes about the amps been taken from the primary at this situation.
