  Ok, I get that about pressing the horizontal button in. I'll do that next.
  As far as the negative scope probe shorting out the signal, that is what it's doing alright.
But, why?
What should I look into, as determining what cause this groundloop?

Nick, 

the blue channel is in AC coupling mode, be aware of that.

Try to have the slowest signal synced on (upper part), so on the 15Khz grenade signal (if you can scope that signal without shorting it out with the ground lead)
Then narrow (delayed sweep mode) to cover 1 cycle.
The lower part should then show a zoomed in part on the yellow kacher signal together with a part of the grenade signal


Concerning the ground loop, i do not know your circuit so i have no idea if and how you create a ground short.
I remember that i could not easily scope my grenade output as it was kind of floating.
So use you diagram and see where the ground lead of your scope ground out someting.
Perhaps you cannot scope that signal using a ground lead.

Nick,

Randomly placing your two probe ground leads can lead to scope damage. The ground leads should share a common connection so that there is little or no potential difference between them. For safe scoping its really best practice to use an isolated ground probe on one of the channels, if in any doubt about the electrical conditions that you are scoping.

  If I connect the scope probe ground lead to the 0.47uf WIMA cap, I can see the signal there. But once I connect the Kacher up, both signals are then affected, or partially lost, also. I had showed that in one of my videos.  As the scope ground lead kills (grounds), the HV signal. It otherwise can be read at the cap, if no HV is also on at the same time, but NOT at the bulb(s).

   I think that may be one of the problems that I'm having, with not being able to obtain the proper sync, with the feed back circuit on.

Nick,

For scope safety, you should be using a high voltage probe (x1000) when connecting rather than just sniffing around the Kacher.
