The European TW125 has a carb heater ........
My dad dismounted another TW we purchased, a cafe race one
He removed this cable but forgot where to attach it, it is a TW125, also attached some carburetor photos so maybe you can identify the model
Note we already connected the one near starter motor and back of the front part of the chassi, so is not that one
Looks like an electrical connector, to me. The "slip" connector must go there and the round "lug" end must connect to power. This is NOT a ground (earth) cable. Look for a power connector close to the carb. I hope my altered photos show up.
Is it not the ground cable for the carb heater?
Power has to come from somewhere. The carb should be grounded via bolts, etc. However, I am just guessing, too. I have a USA TW200. No carb heater and no 125's here.
Fishguy - that point on the carb was my first thought, but I'm not sure that spare wire has a spade end - curious as to why you think it's not an earth though
Peterb - the thought had crossed my mind, but jannaruto and his dad know what they're doing (kinda) - in the absence of a diagram for the 125 or any other experience of it for that matter, it has to be a "hands on" solution
The manual is here http://www.tw-parts.com/macbig2k1/doc/tw125-2002.pdf and predictably, about as much use as a chocolate tea cup
Following this link https://tw200forum.com/forum/technica...-125-carb.html – post #3 – takes you to this link - https://www.yamahamotorcyclespares.c...?uID=812856335 – and if you ignore the “security issue” (it’s safe), then parts 25 and 26 do indeed refer to the carb heater
Now, if the bullet end of that remaining cable matched up to the point on the carb comfortably, then at around 6 degrees temp, the sensor under the seat should send a signal to the carb heater, which makes that brass spade end either a positive or negative – depends if you can first prove that there is one other electrical connection to the carb, which would then make it a negative, provided the other wiring point is correct – but in any event, there should be something connected to that brass spade on the carb
Feeling lucky ?
Check front mounting bolt of the regulator. Should be a cable just like that mounted via that bolt. Cheers
