hi... this is my first post even though i have been a member for over 5 years ... i have a beautiful yellow and black 2015 speed triple 1050r same as wasp's i think...her name is rumble bee .. every now and then she just will not start.. turn the key lights come on every thing primes up push the button and nothing.. sometimes if you keep button pressed in for a few seconds she will start up.. sometimes you can keep the button pressed for ages and nothing.. usually if i take key out and back in again she will start..i have replaced battery and have taken clutch safety switch out completely but still have the same outcome ..please help... just to say she always starts eventually , thank you for looking...
Sounds like a loose or bad battery cable connection. Start at the battery, then at the starter and the main ground connections at the engine block. Use some maintenance spray such as Truck-lite on all battery cable connections to minimize corrosion. Replace the starter relay for good measure maybe also.
I had similar with my 2014 Speedy soon after I bought it. It went back to dealer to get subframe powder coated which took about three weeks. First ride out I stopped to take some pictures and it would not start. As you say everything lit up and primed but not so much as a click from the button. Local dealer collected me and it turned out the starter button cavity in switch block was full of dense spiders web! New switch supplied by original dealer and all good. I have heard the switch can burn out if heated grips or such are wired in through battery terminals or something?
All the above is good advice. When you check the start button, check and clean the kill switch too. Have you checked the voltage on your new battery just in case you have a dud, the ecu is designed to inhibit starting if the voltage is too low which I believe is done to avoid problems with the starter sprag clutch (that was not uncommon on earlier Triumphs). You say it starts if you remove the key and replace, so this might point towards a problem with the ignition switch or wiring to it. There have been a few cases of broken wires around the headstock (which are sods to find), check for tight cables and if moving handlebar to a different position has any effect. Also my 2015 has factory immobiliser which reads a chip in the key so I'm guessing yours does too (it's a module fixed to the airbox near the seat), try your second key to see if that makes a difference. There's a short cable from the bottom of the ignition switch assembly to the top which I expect feeds a pickup coil at the top, check that is undamaged. So many things it could be, Have fun! And don't forget to let us know what it was when you've cracked it.
Cole Yes you have all the good answers here already. That starter button can corrode and cause problems. And really if you miss the start you should let the button go as holding it in that position can also over heat things and damage the connectors on the switch. Let us know how you get on please. Joe
If you have disconnected the clutch switch, make sure to clean it but above all, do not leave it disconnected or bypass it as it has other functions beyond a mere safety cutout. I believe it also plays a role in updating the sensor data for the fuel tank etc. As others have said - dismantle and clean the starter button and kill switch - very likely to be the source of your problem!
Mine does exactly the same. I will replace the battery as it is over 5 years old and the bike can labour sometimes when starting. I'll keep trying to find the problem, and if I do I'll pass it on.
