Today I spent half the morning grovelling on a carpark floor in the pouring rain fitting a new brain to my lobotomised Triumph. After which I had a 90 minute drive home with wet trousers that soaked through to my pants, yuk. I’m definitely feeling the effects of a weeks worth of stress and sleep deprivation 
Fortunately the new ECU was reporting a voltage of 12.4V where the old was was showing 6V. So hopefully that really is the problem fixed and when the dealers program it tomorrow I’ll be getting a phone call to say I come collect a working bike 
Edit: Just had the phone call, they’ve programmed the ECU and the bike starts!!! Will get train tomorrow and go pick it up.
