Led turn signal flash rate problem

So I installed rizoma club turn signals front and back. Look awesome by the way. But I tried to adjust the flash rate and it only works when the engine is not running. Anybody else have this problem? Am I doing something wrong? Land vehicle Tire Automotive tire Vehicle Motor vehicle

What does "it only works when the engine is not running" mean? They never flash, stay on, flash fast? What do they do when the engine is not running?

I'll try to be more clear. To adjust the flash rate you hold the info button then turn the key on. There are 4 flash types you can scroll through. Set at 4. Hold info button again it set to that type. With the key one and the engine not running it flashes at the right rate. When I start the engine it seems like it defaults back to type1. But with the engine off it's still set to 4 and works like it should.

OK, I seem to remember after you set it to the required setting you have to hold the Info button down again to lock the setting in, otherwise it does indeed default back to to original value.

Thanks for the info. That's exactly what I did. It holds the new setting, I checked 3 times, but the flash rate is only right with the key on and the engine not running. As soon as the engine is running it goes back to a quick flash. Turn the engine back off the flash rate is slow again. Just checked it again as I'm writing this.

Hmm, OK. Well on @Fenech's bike I had to add a resistor across one side only, as one side would flash fast and the other slow.
I have no idea why it needs changing at all, as an electronic flasher unit shouldn't need any settings, but there you go.
What you might need to do is fit a resistor of about 100 ohms between the indicator wires circuit on both sides. You only need to do the back ones as they are paralleled and the back is easier to get to.
It's about a 10c fix, as some of the LED bulbs just don't have enough load for whatever Mickey Mouse system Triumph have implemented.

I also have no idea why there are 4 settings. What do they change? Some seem to make the hazards flash properly and indicators not at all, and various weird combinations.

I really appreciate the help. Adding resistors was going to be the next step for sure. They actually included them with the signals. I still don't get why they work with the engine off. 12 v is 12 v whether or not the charging system is working. Filthy gremlins!

So I wired 2 resistors into the rear harness switched it back to type 1 and the flash rate is perfect. I would have just done that in the first place. Oh well. Just more wires to tape into some semblance of order....
Thanks for the silly useless feature triumph. Just kidding still love the bike.

Interesting the way these bikes seem to ignore logic, I currently have a "hybrid combo on my '16 TTR, stock signals in front and an NRC FEK in the rear. Selecting option #2 of 4 fixed the fast flash rate on both sides, engine on or off. I'm planning a swap of the front signals to LEDs, we'll see what happens when I do.

Sorta goofy to reply to your own post but I removed one of the OEM front turn signal bulbs and connected an old LED signal I had in my parts stash. Fast flash with the setting on 2, had to select 4 to restore the normal flash rate.

I think this whole flash rate thing is simply provided as a "one of your bulbs has blown" detection system.
It's been standard on cars to make the blinkers blink fast if one blows so that you know there's a blown bulb, even though they could make the remaining ones flash at normal rate if they wanted to. The Triumph setup thing seems to be intended as a way of reading the current usage (load) from each set of bulbs, and telling it to flash fast if it's lower than expected from two working bulbs.
It would be nice if they'd added an option #5 which said "I don't care, ignore the load", but they didn't so we have to fool the system into seeing the correct load by reducing the resistance.

You may be 100% spot on with your analysis, I really hadn’t thought of it that way. I assumed the changed in resistance was causing the flash controller to lose its mind like on my Duc Hyper when I installed LEDs and had to fab up a resistor network to cure the issue.

If you put genuine Triumph LEDs on you can set the flash rate it only takes about 30 seconds to change, but friends who have put non genuine LEDs on they had to add a relay to slow the flash speed, I original brought the LEDs for my 2013 Thruxton but the LEDs where for a 2016 up models and had to also get the relay for them to work on the 2013 Thruxton but lucky before I fitted them I brought my 2016 Thruxton and they went straight on it without the relay, its set on number 4 flash setting and is perfect.

The problem with using genuine Triumph LEDs is they are so expensive but I was lucky a friend of mine works at my Triumph dealer and I was rebuilding his Norton motor so I got his staff discount for them but they work perfect and changing the flash rate was a 30 second job and a quick change over from original flashers and yes the WC models the flasher is controlled through the ECU and not a flasher relay.

I swapped out the stock front indicators with Laser Star XS LEDs from Canyon Motorcycles out of Topanga CA. After resetting the "i" setting I've had ZERO issues. Also added the NRC FEK tail tidy and auxiliary led brake lights from Hyperlights. All working with no issues at a standard flash rate. No resistors installed.

I've got exactly the same problem (started a thread already, then saw this here). I am not familiar with electric wiring, soldering etc. so I am still hoping to find a solution using the ''Type 1-5'' modes on the bike.
If anyone knows how to fix it other than with resistors, please share.
Thanks,
Ozgur
