Excess smoke in wiring will always cause problems. With the old Lucas systems this was very common, I had to let the excess out of my Norton 2 or 3 times a year, did not realize Triumph still had this problem.
 


Understood.

And the melted sheathing is indeed worrisome. At least you are making progress towards a solution. And thank goodness there was no issue with the R3 itself, just its goodies.

Is it the wire from the switch to the relay? or from the accessory plug to the switch ?

Running from the switch on the handlebars to a black snap connector under the tank, are 3 wires red and blue (I think) plus the pink one which is the one that seems to have melted/softened/expanded its sheath

In hindsight of course, the smoke wasn't coming from the switch but from the nipped wire very close to the switch .... but I know what you mean Ransom .... you'd think all that smoke they store in there would get in the way of the electrons wouldn't you? I think I'll take the bar end weights off at regular intervals and let the smoke out like you used to do.
