Turn Signals Flashing Fast Intermittently

Hey friends. On my 2015 DL1000 my Turn Signals are flashing quickly when turned on but only some of the time. They seem to flash 3 or 4 times and then go to the normal rate. This only happens maybe 25% of the time

They are the Suzuki LED OEM ones sold in Europe for this bike using the included Suzuki Flasher. They have worked perfectly fine for the last year.

They also flash at the normal rate with the Hazards on making me think it’s something with the turn signal switch itself?

I have checked and replaced the Signal fuse in the box.
I have unplugged and replugged in the Flasher

Any ideas?

The next time it happens, pull over and check that both indicators are actually flashing. A high flash rate usually indicates that only one light is illuminating - usually from a poor/erratic connection in the wiring.
I have had a similar issue with mine corrected by opening the L/H switch block and cleaning with electroclean spray.

It could be a bad connection in a lamp socket or wiring harness (or bad lamp), if it only does it on one side. If both, then has to be something common to left and right, like the switch Brockie mentioned.

As OP said, it's LED kit. The symptom he described is typical for turn signals with bulbs. I've never heard of this with LED turn signals.
I have LED Suzuki OEM turn signals kit since 2015 and when I sold my 2014 DL1000 and got new model DL1000 in 2017, I used the same kit, didn't want to let old bike go with the kit. I have never had the problem.
My suggestion is to try to provoke the fault bu unplugging one of turn signals, that should be the front one as it has easier access, and see if the rear starts to flash faster. If it does, then we have the answer: LED turn signals behave the same as bulb turn signals and there must be bad connection somewhere. If not, then the fault is somewhere else, most probably in relay.

Thanks everyone for responding

As Bosnjo suggested, I unplugged the left front and the left rear started flashing fast.

Does that give any indication on whether the connection problem is likely in the front or back? Trying to avoid removing the Top Case, Adaptor, and Tail again if unnecessary as it’s a pain.

Still confused that when the hazard light is turned on, everything works fine.

Should I try to spray some contact cleaner in the turn signal selector shift?

Does it do the same with either the left or the right side blinkers being selected?

Yes. Both sides are doing it (front and back) about 25% of the time. When it happens they blink 3 or 4 times then normalize to the standard rate.

It would be nice to find out, when it starts blinking fast, which blinker is failing, front or rear. My wild guess would be connector under the seat. Remove the seat and look all the way back. You'll see (if I can remember well) two plugs close to the right side of the bike. One of them is for rear blinkers. If there was only one plug, then that is the one. It may have become loose. Just a suggestion for your next step.

I’m back in business!

Bosnjo- Took the rear off and nothing looked loose. But I unplugged the main harness and each turn signal and replugged it all back in and everything back to normal. So I guess one was loose and you were probably right on
