Regarding the "Pulser Coils".  To my knowledge, these units do not "burn out".  They are Passive in the sense they do not carry a voltage/current.  When the engine is running they merely send an electrical Pulse (signal) to the igniter.  Obviously, the Pulse being induced by the rotating magnet.  They fail by developing an "Open" in the windings.  As such I don't see how a failed pulser-coil can burn-out the igniter or that specific part of the igniters circuit. 
In 1980, on my new bike, and two days into a cross-Canada ride, I started loosing 2 cylinders.  I'd pull over, stop the engine, scratch my head and a minute later start the engine only to find I had all six plugs firing.  Ride another 50 miles and the situation would repeat.  I went through this ordeal for a full day and was considering return home.  I can't explain why but this issue corrected itself and I had no other related problems. Not too long after this 8000K trip the problem returned.  The bike went back to  the dealer and the mechanic simply replaced the unit which was failing to fire it's respective plugs but he deduced and explained that it was developing an "open" when the engine got hot. 
Back then when a pulser coil was required Kawasaki supplied an entire assembly with all three.  When I picked up the bike the mechanic gave me my original assembly - minus the defective pulser coil.  I still have it and ironically haven't had a need to use it for a replacement P-coil.    

My pulse coil works perfectly when starting the engine and when it warms up it stops working, it doesn't always fail but it does fail very often.
Maybe the term I used "burn out" was not correct, but what I am clear about is that it fails more than a fairground shotgun.

I already received the replacement from MCG Parts, everything perfectly packaged and protected in a box full of Styrofoam flakes. 


I was about to change the piece when I discovered a detail that confused me again.The old pulse generator has the red cable exit from below, near the magnet on the plate that supports it. 



While in the new generator pulse it is the yellow cable that comes out from the lower part.




In this image you can see the difference between the two pieces placed in the same position.
 

So my question was whether I had to join the cables by their color or by their position in the pulse generator.
I sent an email to MCG Parts asking what to do and they kindly responded to me to join the cables by color, red to red, yellow to yellow.


One more step, one less doubt.

After almost 400 euros spent on electronic components, many questions, doubts, a huge number of hours searching the Internet, and above all many, many expletives, curses and outbursts...

WE ALREADY HAVE A SPARK..

AND BEST EVEN, ON ALL THE SPARK PLUGS!

Regarding the issue of damaged electronic ignitions, I read on a BMW motorcycle forum that the first models equipped with electronic ignition back in the early '80s also had a missing spark coil.
If the engine was turned over during repairs without a spark plug connecting to ground, the electronic ignition would burn out.
It may be the reason why a part of my motorcycle's ignition was burned out.

Wondering how goes the project?

The project is currently stopped, I have had other priorities.

I know that the engine works, at least inside the garage, without having installed the fuel tank, side covers and seat yet.
Little by little I will be assembling the missing parts and components to be able to perform a dynamic test on the motorcycle.

With the arrival of spring and good weather, the season of classic motorcycle rallies begins.
On weekends I enjoy riding the other girls while Christine continues convalescing in the garage.

Here I am with my green t-shirt and his matching motorcycle.
 

In this other image with another t-shirt, this time blue.


You can see that I look perfectly and also well served, although I won't deny that I really want to take a photo with the red t-shirt at fu**ing once.
