Has a PIC 14 pins ? The used IC has 14 pins.

see any difference in the input current from each pulse ?
I don´t see any difference, which tells me, that the 2 coils are
probably energized together in a bridge configuration as I have
Well, I could be of course wrong, but the scope shots tell me this
configuration which I have drawn.
