2 cylinder Force 50, no spark!

Hi all, writing from the uk, I have what I believe to be a 1992 Force 50 2 cylinder that lost all spark, coils and plugs tested fine, unplugged the kill system from the CDI and Still nothing, hoping somebody here has some electrical mechanical knowledge they wouldn’t mind sharing? Any help hugely appreciated, unplugged the yellow wires to the regulator and still no spark, this led me to believe the stator was at fault so I removed the flywheel and stator only to find some heat damage to the trigger, I replaced the trigger with a second hand unit from the states, also changed the regulator and purchased a red stator conversion complete with the adapter, I have fitted all the replacement parts yet still have no spark, I am a mechanic by trade but never messed with outboards before and by no means am I an expert on electrics, however I have done some research and managed to find some info relating to the resistance readings I should be getting from certain parts, all seems to be in order according to manufacturers spec so I am at a complete loss as to why I still have no spark??? Seems to be many google results relating to people having similar issues, could anybody shed some light on the subject or advise me on what to try next as I am now at a loss and considering replacing the CDI unit at a considerable cost ��
Many thanks

Is battery fully charged, Most outboards require 200-300 RPM to provide spark, Have you tried CDI electronics.com for trouleshooting
 
Hi Johnny, yes I’ve tried and tested the battery, even pulled the one of my van and tried that just in case, only info regarding troubleshooting I’ve found online I have done yet I’m no closer to finding the issue
 
I strongly recommend you buy a DVA adapter for your ohm meter (about 30 dollars US on Amazon) and test the system.

At cranking over rpm the stator should put out about 200 volts, the switch box around 150. If not, that's the problem, and you HAVE to use a DVA adapter to see it. Great tool for your toolbox!
