Ignition current ramp

Hello. In the diagram if I connect an amp probe where the red circle is drawn. Will I'll be able to see the current ramps on all four coils or only on coils 1 and 2? This is a waste spark system. thanks.

That will only give you the ramp for the coil for 1&2

That will only give you 1 and 2, you would need to be before that main splice to see all of the coils.

I've been taking a database of waveform from my truck and this is my first time taking a ignition current and thanks in advance for any input you may have. I used a fuse breakout lead at the junction panel and connected the amp probe to it. A sync probe on #1 cylinder for ID. The firing order is 1 3 7 2 6 5 4 8. Cylinders 1 & 6 are companions on a waste spark. Am I correct in noticing the #1 firing on exhaust on #6?

A close up look on the current ramp. Oscillations in the beginning.

Wasted spark systems fire the spark for each cylinder once for each crankshaft revolution (to put it another way once 180 degrees camshaft rotation) so if N#1 cylinder is firing at 15 degrees before TDC on the compression stroke N#6 will be at 15 degrees before TDC at the end of the exhaust stroke. It is probably simpler if you consider the example of an inline 4 cylinder engine where 1 & 4, and 2 & 3 are companion cylinders.
Wasted plug firings on the exhaust stroke can be spotted by the lower peak voltage which is about 50% of the peak voltage on the compression stroke.
To caputure genuine power firings the trigger voltage has to be
set above the peak voltage of the wasted spark.

With compnion cylinders one gets a positive spark voltage the other negative.
As this can be confusing it is best to invert the trace on the scope to make it much easier to read.
