I hope that Triumph will do a good faith compensation for the matter of less than a month.

One wire break is definitely inconclusive but could also be indicative of too much strain on the wiring harness. I'm curious about one thing. I've already removed my rectifier/voltage regulator from the forks and it seems like that relaxed the harness significantly at the steering neck, but I no longer have a comparison.

If you observe the pull of the harness (bars turned to the right) and then disconnect the two regulator connectors (hot wire and ground on the left, as your looking at it from the front, and the alternator wires on the right) and turned the bars to the right again - is the harness significantly reduced in movement? The connectors just pull straight up off so that's a pretty easy test.

My IMHO take on the clutch cable is that too much movement in the harness is the primary cause of abrasion by the clutch cable and also, the cable has little or nothing to do with pulling wires apart at the neck. To use a medical analogy, the whole recall thing could be more like treating one symptom, rather than addressing the problem.

Full throw right to the lock is a place my T120's steering never goes. No wiring problems since new, knock on wood.

With 3 yrs of history and probably near 100k bikes out there, the majority of folks have likely never had a problem with their wiring. I haven't either (and second that knock on wood) but saw what I think is a potential long term type problem. A lot of riders have reported problems and it would seem from recent posts that T is out of warranty replacement harnesses - not a good sign. As soon as I found that T had gone to a frame mount regulator for 2019, I went ahead and made the switch. (I don't think they drilled a couple of holes in the frame and relocated it behind the radiator as a styling update.) In the process I noticed how easy it is to slip the connectors off the regulator, and so I proposed the test for those who may be curious about whether they could relieve some of the movement on the harness, without having to do the relocation to find out. I wouldn't think that full lock is requisite to having problems, but it surely would increase the potential for them.

As readers are likely tired of my recurring theory on the subject, having bled all over any recent threads on the topic, I am retiring from further comment on the subject of wiring looms. That is unless I ever actually have a problem.

Streetiger, as someone with wiring issues, I am very appreciative that you took the time to think about this problem and offer information to help fellow Triumph owners. All suggestions are helpful and when we piece together everyone's thoughts and experiences, maybe we will come up with solutions. Thank you!

Dropped the SC off yesterday, needs a new loom & none in the country (AUS). Had the clutch cable reroute recall done a few months ago but first symptom was instrument panel resetting clock and trip meter, then the indicators went.
Had a play around the loom wrapping around the headstock trying to ease pressure but it seems to me the small metal guide bars (?) that stop the forks rubbing on the loom caused a kink in the wiring going to the instrument cluster. Kink plus stretch = $#!+
Hopefully no more than 10 days / 2 weeks without the bike... 😞

I just got my Street Twin (641 miles) from the dealership where it sat for 2 months waiting on a new harness. If you turned the handlebars full right all the instrumentation would cut it....turn bars back left everything would come back on.Triumph warrantied a new harness but they didn't have any in the US. for a while. Seems to run alright and there is a bit of slack at the steering head. Glad to have it back and I hope it won't act up again for the length of time I keep this bike.It's not the only bike I have right now in my shop but it is the first Triumph I've ever owned..

One solution presents a second problem. On my old Street Twin (sold it a month ago) I fixed the tight right lock issue by doing as one guy above did, just extended and shimmed the stock plastic tidy and freed the clutch cable entirely from the tidy. The second issue that occurred was now that the loom was free to move back and forth a little, on a full lock LEFT turn the pointy end of the stock headlight mount dug into the top of the harness exposing wires. I took a dremel and ground off the point of the headlight bracket, or you could buy an after market bracket and save the grinding. There is nothing good about the way the harness is routed, there are more than a few similar but entirely different issues concerning same.

2 weeks and new loom is done. Picked up and rode the long way home, nice way to end a Friday. Will have a closer look tomorrow and check the routing of the various wires and cables.
But for now, happy to be back mobile ...

Same here...This is my second week since getting my Street Twin back with a new wiring harness replaced while under warranty. Everything seems fine and I to am happy to be able to ride my Triumph which just by the way just turned over 1000 miles today.
