Hi all,
Out of a sudden, my blinkers stopped working properly. They are flickering unregularly on both sides in the front and the back. The flickering is simultaneous in the front and back so when the front blinker flashes faster then the rear one is flashing in the exact same sequence. This problem started like half a year ago and then disappeared again m. now it is in the winter garage and I turned on the motorcycle this morning and tried out blinkers and the issue is back again.
What can that be?
Thanks a lot

I think the fault is the relay that controls the turn signals. They are inexpensive, easy to replace. Locate the item with the help of a repair/maintenance book (available on ebay) determine the spec and purchase a new one, also available on ebay. I have done this to other motos. Relays do fail. Good Luck!

Most likely it will be a mass wire that has come loose or is breaking.
If you ride an older RC it is also possible you need to spray the electrical connectors with 'electric-clean'.
Check and clean the left hand, handlebars, switch cluster.
Undo the 2x screws from the bottom, separate the two halves and spray electric clean into the switch.
Because all four indicators present the same issue it is most probably a negative/mass wire issue.

Hi everyone :),
Another attempt of asking. I have noticed that the indicators only flash veered Lee when the engine is turned on. When it is turned off, it all appears normal.

Would this help locating the system? KTM unfortunately rejects warranty because I have changed the tail tidy….!!!!
