I screwed up big time....

Great post Max and very measured. As an example of the benefits of Max's methodology in action. The crankcase position sensor is a known weak point on the 90's era Triumphs and it has fooled many a skilled man in to tearing down carbs, changing the HT leads, spark plugs, checking valve clearances, swapping coils, you name it. The shame was it was easy to get to and easy to test with a $10 multi-meter, it was also quite a low cost item to replace. If only they had started right at the root as per Max's diagram.
