hi, i have a 2002 triumph tt600 with 20k on the clock. i'm having intermittent issues with it 'cutting out'. the bike will start fine to begin with but cuts out mid ride. when it does this the engine management light can be seen to continuously flicker and the main power relay can be heard flicking on and off rapidly. if i turn the ignition completely off and on again, usually the engine management light and the relay will continue 'flickering' but eventually the fuel pump (which is fed by this relay) will prime as normal and the bike starts only to cut out again a mile down the road.
at first i thought it was a faulty fuel pump which i then replaced only to find out it was being controlled by this relay. i've tried replacing the relay but no difference. i tried checking various things that were suggested e.g. side stand switch, kill switch, battery, rectifier, bad connections, alarm, all seem fine. i then booked it into my local triumph dealer who had a look and said it was a corroded coil pack (for the spark plug), they replaced this and the plugs but 50 miles later and the problem has reared its head again.
i would be grateful for any suggestions or ideas as i've contacted my dealer again but they have a 3 week waiting list!
