    Hi everyone.

    I tried to make this thread entertaining to bare with my abysmal lack of technical knowledge. I like to ride 'em not fix 'em.

    I recently changed my levers to TEC ones, this might be relevant further down the post, or not.
    Because I'm an idiot, I initially just replaced the clutch one, bim bam boom, easy peasy, bike no starty.

    [​IMG]

    I forgot to put the little cylinder thingy, from the OEM lever bolt hole to the TEC one. Don't knows the name of the thing.

    [​IMG]

    Alright all good.


    OOoh that looks sweet was I thinking (the all blacks levers), Imma go for a ride !
    And off we go !

    [​IMG]


    Parked the bike, went away for a couple of hours, and saddled back up.

    Here comes trouble:

    Key in, electrics whirring, okay. Clutch in, Starter.... The bike reboots ! like if I just turned it off and back on. Like a computer crash.



    Reminder: I am not home.

    [​IMG]

    I turn the bike off, back on,
    Key in, electrics whirring, okay. Clutch in, Starter.... The bike reboots ! Again !

    I tried a third time, a fourth time... That's it. Battery must be dead, but why ? Off with the helmet, the gloves, I'm raging.

    I try one last time, the bike starts like if it was just coming out of Hinckley...

    [​IMG]

    Home at last. Turn off the (warm) bike, try to reproduce... No way.

    Any suggestions ?

    Carry the oem clutch lever with you for a while. I have seen people change these time after time and they are not right for the bike unless you buy top notch ones. Also clean and check all the safety switch gear to make sure they are doing what they should.
    Ride Safe & Enjoy

    That sounds very plausible...
    Edit : Googling exactly that, it seems more and more plausible that this is may be the source of the problem.

    You can maybe test the clutch switch. The one on my Bandit went just before I PX'd it. To get it started, you just place a screwdriver tip or something similar between the contacts of the clutch switch just while you press the starter button. Obviously I don't know if yours are accessible.
    What bike is it ?

    Battery terminals corroded or not connected tight enough. That would cause a higher than normal resistance so that when the current surge of the starter motor happens the voltage seem by the ECU drops too far causing it to reboot.

    i have few simple tests to run before to see if indeed this is the cause.

    That issue has nothing to do with clutch lever or switch - if the clocks appear to be resetting then it is a voltage issue - sagging when attempting to start due to either poor connection or discharged. This is a T100, yes? EFI model I presume given the clocks re-setting?
    If the battery terminals are good & tight, then, if you have a voltmeter, check the voltage between the terminals with the ignition (and therefor lights!) ON. That will tell you sate of charge of battery.

    (ignore image below - I thought initially that was the type of switch you have, most triumphs use - but it's not if that's an EFI T100 - I can't seem to delete it so please disregard)

    no idea on the problem, but a very entertaining presentation.
