Hello All,

I have an 18' Thruxton with the cafe fairing and NRC tail tidy (both installed by Tampa Triumph) and about 1,000 miles. ALL of my turn signals and hazards stopped working today. I checked the fuse box and didn't even locate a fuse for the signals. Any ideas before I ride or trailer all the way to Tampa from Orlando?

Thanks!
Chris

A quick update for those considering the NRC tail tidy setup or similar. I dropped my bike off at the dealer (Fun Bike Center in Lakeland) to trouble shoot the issue. Apparently the difference in electrical draw between the LED NRC tail tidy signals and the stock front turn signals fritz out the bike's computer. The dealer hasn't been able to fix the problem. They're ordering LED replacement bulbs for the front turn signals, then will reset the computer and see what happens. Not real happy that this NRC kit was sold to me with no mention of the potential issue but I'm confident they'll make it right. In short, talk to your dealer if you decide to mix up the bulb types on your Thurxton's signals.

I have the same set up with my ttr that I've installed myself (fairing and nrc tail kit) for over 3000mi. I haven't experienced your issue. The shops finds does not make sense to me unless there is a short in the wiring somewhere or the relay for the turn signals is internal to the computer like some modern cars have in thier body control modules. Putting led front turn signals on will just increase current flow and make the blinkers blink fast. I'd recommend an adjustable blinker relay or adding some resistors to the blinkers to slow them down to see if the issue returns. I've also seen a loose connection on one of the plugs in the headlight housing cause this issue. If you or your shop you went to can get a wiring diagram for the bike and post it here that would be awesome. My two cents is done lol. Please keep this updated, I'd like to learn more about this bikes electrical system from us on here since the all mighty google comes up short.

Thruxton R , there is no relay for blinkers, all done by ECU. Flash rate is adjusted with the “i” button. unless of course you are confusing the ECU by using a mix of led and incandescent.

I have incondecent front and led rear, how do you adjust it with the "i" button? I wouldn't mind trying to see if I can slow mine down a little bit.

After installing my NRC tail and LED fronts, I installed the fronts with resistors and haven't had a problem. Normal blink rate.

Press the "I" button and hold then turn on the ignition let it do the normal cycle while still holding the button it will then go straight to the blinker settings you will have 4 settings to adjust number one the fastest press the button till you get it to number 4 then hold the button to set it on that number then things will go to normal once set, takes about 30 seconds to do.

Lots of good suggestions here. Much appreciated. Update from the Lakeland shop - still can't figure it out even with their "electronics specialist" - geez... I do have a mix of incandescent (stock front) and LED (NRC). Even though they blinked just fine for 1000 miles they all of sudden stopped. Anyhow, they're ordering LED replacement bulbs for the front housings and we'll go from there. If they're still stuck, I'll have to pull up this thread and give them some ideas. Thanks goodness I have a backup bike or two:).

So I have an NRC FEK , I was going to install this weekend. Do I need to use LED bulbs in the front, a relay,or stock fronts and adjust the blink rate with the "I" button?

I found out today that if you have the nrc kit with oem front turn signals, and set the signal pattern with the I button to anything besides one, the hazards don't work. Just for everyone's information.

I'm fairly certain this has been a known thing unless your switch to LEDs all around. I had this issue temporarily when I had mixed turn signals for a few days.

Got it LED's at all four corners. Can I get LED bulbs to fit the stock fronts? Where and does anyone have a part number? Thanks.

It doesn't matter whether you use all LEDs or a mix. The indicators on each side are in parallel, so the bike has no idea what the relationship is front to back.
The ECU measures the current draw. If it's too low, it won't start flashing, and some LED bulbs are such low power that they cause this. Weird, but true.
If it's high draw, like incandescent bulbs, it's happy. Most LED bulbs fall between the two, and might only draw 1.2W (0.1A) each, which is way below a 21W OEM bulb (1.7A) each, which is why the ECU gets confused reading the operation. If you struggle getting the flash rate right, just buy a pair of 15 Ohm resistors like these: https://www.ebay.com.au/itm/Gold-Tone-25-Watt-Power-15-Ohm-5-Aluminum-Casing-Wire-Wound-Resistor/273374047293 from any electronics store.
Stick them between the wires on each rear indicators and you're done. No need to do the fronts, as they are in parallel.

Thanks, JSOBELL, I installed teh NRC kit, jacked around with the kit spacers, then made my own to get the LED fully visible below the rear cowl. I don't remember what setting I have them on, but it is blinking at the right speed, the flashers are working fine. Time will tell.

I want to thank Chris for posting this question. I just had the same issue with my 2016 Thruxton R after riding the bike for ~ 3000km after installing the NRC fender eliminator. It stopped working without notice and the resolution was to install the NRC LED front signal units which cost me about $90 for the pair and they were easy to install. I did need to hold down the I button and change the signal setting after installing the new lights. I found Type-1 was the best for my bike.

I just installed the NRC kit yesterday and ran into the same problem. Was flashing fast, then when I did the Type Change to 2 it blinked correctly until I hit the emergency flasher button and it all stopped. Now the signals don't work front or back, only the brake light. I just ordered some LED fronts. Once I put those in and reset, will it work again or am I looking at some sort of computer issue now?

You should be good to go once you install them. I was told by my local triumph deal that I may have a computer issue, but once the lights were installed it all worked. One thing to check is to disconnect your front signals and see if the rear starts working. I did that and it worked. Once I knew I was getting power back to the rear I knew the front light would solve my issue.
