Thanks, guys, but this is all new to me. I'm an old-fashioned mechanical chap with no experience of tuning or interrogating computerised engine management systems and I have no equipment/software yet to do so. I don't have a OBD/plug in and reset facility and don't want to connect one, if it might lock out the inbuilt tamper system, without first inputting a pass code.
All I'd like to do is find out if the amber warning is ligitimate or if it has lit up just because I've unplugged the harness, coil and fuel tank connections to access the spark plugs. I've seen a couple of generic diagnostic instruments on t'interweb but don't know if they'd give a 'reset' function or are 'read only'. Does tuneboy or tuneecu give the full functionality of the triumph system, without the need for a passcode? Are they readily available for quick delivery in the UK? (I'm off to Switzerland in two weeks' time)
TO Rocket: '3 hot/cold start cycles' I'm not clear what you mean by this - Start it, run it and ride it out? I take your point about shouting, and I apologise. The machine defaulted to capitals last time I was on-line, this time it's normal. Computers? I love 'em!
