2017 turn signals

[SteveThe Snakes]

Anyone have experience with turn signals not working. I have power at the left switch with the horn and lights working fine. But the turn signals don’t work at all. 
Is there a wire I am suppose to check coming into the switch. All fuses are good. 
Here is a picture of the plugs for the left switch. Maybe they are the same for previous years. 
It has a Sicass left switch and I tried the stock one also but nothing.

relay ?

Hum I only see a flasher in the parts schematic.  But there are two relays in the air box or one I think could be the flasher? I wonder if it could be the flasher. But when they go out on cars the light usually comes on but doesn’t flash.

The flasher , atleast mine is behind the head light

I think the headlight power and turn signals were part of the same relay circuit. It's K12, the 1st relay next to the airbox door. They are generally reliable. I may have checked the ground connector on the frame/ coil bolt. In the case of a 2017, it may be worth stripping back some of the sheathing to look for a broken ground behind the steering head. Orange was the common wire per notes I kept on wiring.

I cured my turn signal problem. Took them off when 2017 350 EXC was new and never put back on. I'm old and can not ride well in the woods always crashing. 

Also i live in WV so Johnny Law doesn't really care about all that. Headlight, Taillight, Licence Plate.

I guess they changed the 17’ up.

It looks like there are two grounds next to the coil. They both look good but I will check again. 
From the parts diagram they seem to call the relay under the seat the turn signal flasher. However there is two relays under the seat. Maybe I should order one and see? 

[Burnrider]

Actually there are 3 relays under the battery box on my '17 500 EXC. Info from the workshop manual electrical section. My 500 also has the flasher behind the headlight mask.

A lot of my friends in the NW have done that. More of an issue for the California riders than most places.

It looks like your blinker indicator light is unplugged. The green one on the left side of the dash. I don’t know much about it’s circuit, but I remember that if switching to full LED blinkers, the indicator bulb must be switched, as well as the relay. Maybe plugging it back in will complete the circuit? Just guessing.

I think it just pulled out of the housing it goes in. The wires were all hooked up. But I will look again.

Is your flasher a aftermarket led one. I know I put one of those on my 18’ and I think it’s behind the headlight.
But my sons 17’ has the stock turn signals up front so it doesn’t have the led one. I believe when you do all leds you need the led flasher. I am working on his 17’ and didn’t see a flasher behind the headlight.

Yeah I don’t see a flasher. Just wire plugs on the 17’. The bulb for the indicator is wired up and just pushes into the indicator housing. 

[Burnrider]

Yes, an LED flasher. The stock flasher was zip tied to the 6-wire multiswitch connector from KTM. It' a  1" cube which doesn't look to be present.

The two wires going to my flasher are an orange wire (common or gd?) and a yellow wire with a green stripe coming out of the smaller wire sheath from the harness.

I thought the 17-19 would all be the same but maybe not?
I just removed all the stock lights on my 19. Sicass LED in rear and Tusk LED up front. You will have to have the relay which looks like you don't have one up front my the headlight?
My 19 and even my 07 had it here. Plug and play.
But after hooking it all up the rear worked fine but only the left front worked. Right front didn't. Brown ground wire to ground on the LED had to be reversed? No idea why but once I flipped those the front right worked fine.
Just my two cents.

Car flashers do usually not flash, but I’ve seen them completely go out and not complete the circuit to even light the bulb. Should be able to unhook the flasher and just jump the wires and it the circuit is good they will light. Then you just need a flasher. Just a cheap test light can tell you allot very quickly, power or grounds.

Hello, If I recall, I have a Yamaha so I do not know if KTM is the same but here is the theory, Turn signal circuits switch voltage from left and right lights after the power goes through the replay. What I mean is you have left and right lights, OEM's use the switch to provide the power to the left or right signal.  Also think of it like this, First feed power to the turn signal relay, TSR,  then send power to the handlebar switch, now when you click left TS on it feeds power to the left bulb then power goes through bulb to the ground , light comes on. Now you also have to remember that the turn signal relay works off of resistance (to blink) , so generally if you do not have 2 working lights, (LED bulbs can cause a resistance issue keeping TSR from working correct, not enough resistance), the turn signals generally will not blink. So one of the reasons OEM's  create this circuit is so they only have to use one TSR. So check get a test light check power to TSR then to each bulb then check grounds. Sorry for the long post, and once again this is a generic explanation your bike may be different , check your bikes wire schematic.

Some great advice from you guys for me and anyone having this issue.  

Here is what Sicass emailed me back this morning. 

“My guess is that your flasher is blown. Power for the turn signals goes through the flasher first, then to the control switch, then out to the turn signals.

You can test this by disconnecting the flasher and jumping the BIKE side of the connector with a paper clip or small piece of wire. This will make the turn signals come on solid when you turn them on at the control switch. The trick is going to be determining what caused the flasher to blow... I would check over the turn signal wires and make sure there are not any that are pinched, or broken wires.”

So where exactly is your relay if not under the headlight area?

I think the parts diagram shows it under the seat? But if anyone has a picture of the stock flasher behind the headlight on a 17+. That would help. I have another 18’ in the garage but it has a aftermarket led flasher. Number 7. says flasher.
