what they call the change over relay, which is the one that dims the power from the headlight when you press the starter button. it's a 5 pin little blue relay, i just made a circuit by joining the 2 red/white start button wires at the relay. I have a feeling it is some thing simple that I have missed.
Shorting just one circuit i.e. two pins does not replicate the conditions it operates under - you need a circuit diagram, see what happens with the other 3 pins.
none of them relays, I got the relay from triumph. i agree with it's not it's normal condition, but it proved that the starter button, starter solenoid and starter work. but not sure of the ignition side, in the haynes manual they call it the headlight cutout relay.
I should have pulled my own to see what it was They are £3 micro relays. https://uk.rs-online.com/web/p/non-latching-relays/9156644?cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Relays-_-General_Purpose_Relays|Non-Latching_Relays-_-PRODUCT_GROUP&matchtype=&aud-830986524469la-445410761225&s_kwcid=AL!7457!3!243845768305!!!g!445410761225!&gclid=EAIaIQobChMIxoHSi66k5wIVSrTtCh0oYQFYEAQYASABEgJtb_D_BwE&gclsrc=aw.ds I won’t ask what Triumph charged 4x?
That relay shows Blue/yellow as commom for the switch so 3 and 5 should be connected together to bypass
When its powered there will be 12v on one of the pins to the coil, i.e. 1 or 2 so you need to do that as well and trace where that goes. And the other will go to earth - possibly thats what energises the relay via the starter circuit. All those circuits need chasing to find a possible fault.
it was only £7 from triumph, thats why i got another, one of the first things i did when the bike wouldn't start, was try a starter motor i had off a Kawasaki, without putting in the starter hole, with just the wire on and a earth, and when i pressed the button it turned over, so thought it must be starter motor, as I tried it on a battery and it wasn't good. but new starter motor and just the same. the engine does turn over so not seized. it's as if the relays are not strong enough, as i get one click, then have to wait for a reset before i can press again. I checked all the feeds to the relay, and all as the book says. the blue/yellow wire is from the fuse box (headlight) blue wire to what they call dimmer switch, which i take they mean high low beam. the yellow/brown wire goes to ECU, now the way i by passed this, that wire wouldn't get any live feed, so i will try a different way tomorrow and report back, that may get me my sparks

tried to feed the wire to the ecu and still no difference. I am starting to think it's a ECU fault. is there any one who can test them ? or do I have to take the bike to a triumph dealer ? thanks
