I finally got round to washing the Girly after France then was going to ride it back to the garage and..... no go. Same as last time, churns over but no firing.
I had a think and initially convinced myself that it could be sidestand switch because clutch switch stops it turning over, side stand switch stops it running. I wanted to do a quick check on the switch, but found the plug is under the airbox and the cable is routed behind the waterpump

FFS Mr Triumph why would you do that???? SO, after removing the indicators, Bagster cover, battery etc etc I finally had access to the plug. I disconnected it and checked the switch; all fine. Then I remembered that you have to engage a gear before the switch acts as a cutout, so the last half hour hadn't helped.
Next I did a quick check of the injectors and they weren't firing. Last time this happened remapping sorted it so I got the laptop and blew in a new map. Zilch. Nothing. Changed the ECU. Still the same. But at least that proved it's on the bike somewhere....
While hooked up I decided to check the codes and found number two coil open circuit or short circuit. I gave everything a wiggle and voila, she fired up.
So here's today's so far unproven theory. The injectors and the coils share a common 12v feed; they are controlled by the ECU which grounds each coil or injector when it wants it to fire. In order to take down all the injectors (and probably the coils as well) there has to be either a short to ground on the 12v feed - which would almost certainly result in either a blown fuse, burnt insulation or both - or a leak to earth via insulation breaking down in a coil, which may not be enough to blow the fuse, but could drop the volts enough to stop the coils and injectors working. This is supported to some extent by the fault code in the ECUso tomorrow's job is to change the coil. As it happens I have a spare....
I am beginning to tire of this

Oh, and having taken the Bagster cover off after all those hot miles in France, I find suddenly I now have decal blisters
