- The speedo is intermittently showing zero while riding. It’s been getting progressively worse as time goes by. It’s a bit of a journey to fault find the cause but I get there in the end. Couple of links below 1st for the LED light and the other for the KTM wiring diagrams.

this is a single video on whole internet which provides solution to this problem!! nobody has even made video a on this! Thabks buddy for helping us out
You are a legend mate.
Thank you so much for finding the root cause.
Just wanted to say thanks for the great video! My gf was having the same issue on her 2013 Duke 390 and I was able to fix it by following your instructions and installing the LED headlight. Thanks mate, bloody legend!
Led bulb voltage and wt let me know bro
thankyou very much...i reallly apreciate your video...mi ktm 990 2012 speedo was going to zero and abs light turned on....got a new battery and a led light and now is perfect! thanks for taking the time not just to find the issue, but to record the process, edit it and upload it to youtube....god bless you good man
Hello. check the resistance from fuse 1 to pin 11 on the dashboard. I had 14 ohms. I disassembled the ignition lock and cleaned the contacts. the resistance has become less than 1 ohm. after that, there were no problems with the speed readings even once.
I need that bulb - just kidding!
This is a very interesting video. I've been struggling with this issue for a while, culminating with my bike's battery outright dying on me. I run the same brand bulbs (Novsight) but mine comes with the little fan and ballast. Anyway just like your Duke, my speedo behaves almost exactly the same except that when I use maybe 20-30% throttle input, the speedo works fine. If I wring it out, the speedo dies but if say coming from speed and I'm just coasting with the throttle off, it reads fine again.
A local shop tested out the bike where my battery (very old, very stock) was replaced along with a new regulator / rectifier. Issue is still there but I don't think my battery is fully charged yet. I'll charge it up and get back here to see if the issue gets resolved.
Been dealing with the same issue for almost a year now.
Hi,
Thanks for the detailed video. I am currently facing similar issue on my Duke 200.
The speedo works just fine when the headlight is turned off. But the moment I turn on my headlight, the speedo will occasionally show "0" while riding.
The service center guys changed the stator coil and recharged the battery and still the issue persist. So now I am going to check the power consumption of my light bulb.
However in India i couldn't find that LED bulb without the fan. I guess I might have to look into some local hardware stores here.
However great video and I will keep you posted on my issue.
Thanks.
Thanks for your effort and informative video. My 2013 390 Duke has the same problem and seems to do it more when I first start riding. I don’t ride ever day so I put your theory to the test and put the battery on charge and then took the bike for a test ride, knowing that the issue usually occurs more when I start riding. With battery fully charged the Speedo didn’t drop out once. Also think I’ll change the headlight over to an LED. Thanks again. Let me know if you still have the other bulb 🤷♂️.
Yep still got it.
Send me an email to
Don.knight@bigpond.com
With your address and I'll send it your way.
Very informative video. Thank you, sir. BTW, does this Led needs an relay? TIA
Same circuit at the original bulb. Plug and play.
Hello! Please check the voltage fluctuations at the battery terminals at idle using an oscilloscope. My volts jumped from 10.5 to 14.5. replacing the battery with a new one fixed the speedometer error
Awesome detection skills 👍
How is the longer term trial going? Any issues with heat or moisture?
Thanks,
Neil
Interesting enough, after the bike sits for a few weeks (winter here) the speedo has a few hiccups until the battery fully recharges then it's fine. I'm wondering if there not a voltage regulator in the speedo circuitry that's on the way out.
Time will tell.
@@mostlymotorcycles. Yep - it does definitely seem to be related to the charging circuit in some way.
I've ordered one of the headlamp globes you recommended and I'll put that in and see how it goes, but to be honest I suspect my stator is on the way out, but if the lower power globe helps extend it's life then thats good for now.
My speedo started playing up a few months ago literally after I'd over filled the pertrol tank and fuel spilled out over the bike. Once I started riding from the petrol station the speedo started playing up (my thoughts at the time was that the fuel had gotten in to some electrical connectors and dried them out/increased resistance so I blasted a few with WD40). Of course it could simply be coincidence that the fault appeared at that time.
It's been intermittent since, and I recently come back to Sydney after 3 months overseas (and the bike actualy started on the third attempt without doing anything which impressed me) - so I fully recharged the battery overnight, tightened up the battery connectors and the speedo worked fine - until my next ride when it started reading zero again.
So with a fully charged battery it works (my battery is only about 1 year old)
My bike is 10 years old (only 15,000 KM) but there are so many annoying faults occuring, like the dodgy clucth switch which makes it stall for no reason - it fails when you stop at traffic lights or a junction) and my fuel pump went and started leaking fuel - that integrated unit alone was $650 and with mechanics labour it was expensive....
The new 399cc Duke looks interesting though and I'd like to try the new 400cc Triumph when it lands here (be a few years before I can afford a 2nd hand one of either though I'm sure)
Anyway, thanks for your help - love your work with the oscilloscopes etc , and I'll let you know how I go.
Cheers,
Neil
Keep me updated for sure.
Hi. Maybe you already know what that extra button is for but to answer your question, it is to disable the rear ABS. KTM calls it supermoto mode. You just have to long press it.
Mine stopped working when you press it longer than 3 sec.. what could be the issue
@@DreamGrowls There's a process in the service manual using that "secret button" for raising the RPM limit and shift indicator light.
@@NicksBikes yea I used to be able to do it earlier.. but doesn’t work now. Took it to the Svc, they can’t seem to find out the problem either.
@@DreamGrowls I was using that button to turn off the abs. front and rear.
Thanks alot... Great video. Im also have this problem for long time.
Have the same issue with my sons Duke 125. Will take it for a spin later and see if the headlight goes out when the speedo drop to 0.
By the way, did you also try with a cheap led ligh bulb?
Tried taking the bike for a ride without the headlight, and no speedo issues. Ordered a led headlight and position light.👍
Weird though, looking in the manual, my battery is charging quite a bit higher than the lower limit..
Very interesting. keep me posted on how you go with the led.
Hello, first thanks for the video. I have the same problem with my 2013 Duke. I'm thinking about buying the LED bulb but I have a question. In my country it is mandatory to drive with the lights on, as soon as you turn on the ignition the light comes on. I tried turning off the motorcycle on a descent and turning on the ignition (which also turns on the light), but the speedometer continues to show zero from time to time. If the motorcycle is without the engine running, shouldn't the speedometer work properly, since I think the stator isn't working?
The light will come on when the ECU detect rotation from the front wheel.
Maybe try disconnecting the connector to the bulb then go for a test ride. Not at night lol.
Check the comments for other peoples faults on the same issue.
Hi, so if I got it right, the issue is bad stator. Correct?
The problem goes in this order: speedo + headlight works after cranking up the vehicle -> bad stator -> doesnt charge battery properly while the headlight consumes power from battery -> battery voltage drops -> speedo stops working once the voltage drops below 9V -> Headlight also stops -> battery gains voltage -> cycle repeats
My question is: My duke 390 also has same issue. It's 2013 model. Mine doesnt have always on headlight. Then why does mine have the same issue? Also, isnt replacing headlight with LED light not a permanent solution? Why is the speedo going off after a certain speed, while coming back on instantly after going below 60kmph? Shouldnt it stay off no matter the speed?
Sounds like a different issue to mine.
Your right It's not a permanent fix if the stator is failing, but fitting a low wattage bulb may make it hang in there a little longer.
Check a previous comment from a dude who traced his issue down to a faulty contact in his ignition switch. This was causing an intermittent low voltage to the speedo cluster.
Hello, thank you for your video on the topic! I have the exact same issue on my duke 390 2013. I think this issue started to appear after I washed it. Maybe water got in somewhere and started to corrode some wires, increasing voltage resistance? Is there already a definite solution or is my best bet to change the headlight and clean the connectors in the dashboard?
If it started after you washed it, id go with cleaning the connector. If no change, try just disconnecting the headlight to see if it helps.
@@mostlymotorcycles. Thanks for replying! This afternoon I will also call a ktm dealer to ask if they have experience with this problem, otherwise I will try cleaning the connectors
My ktm Duke 390 bs3 in speed is not showing some times it shows but always it is showing zero ...I have checked in ktm service centre and local gurage also ..I have chenaged speedo meeter wire also what to do sir any solution from ur side
Hello sir . My 2014 duke 390 has off switch for headlight still i am facing same problem.
And i have tried charging the battery fully still it doesn’t solves problem temporarily.
I checked the battery with multimeter. It charges normally as i start bike. Eo its not the battery issue
There seems to be lots of different problems causing the intermittent failure.
Check the other comments. Ther may be a solution that's works for you.
have the same problem with my old duke 200. im already using an LED headlight but going to check a lower ampere if it fixes the problem. Im just thinking, is adding electrical accessories gonna affect the current and just worsen the problem of the speedometer going to zero? or is it going to wreck the stator?
Seems the stator in the early Dukes is a little week. I've heard of quite a few failing.
If the accessories are things like seat of hand grip warmers those do pull extra amps, could cause an early stator failure.
@@mostlymotorcycles. thanks man, i'll consider changing my battery to a higher amp hour, see how it goes if it solves my speedo going zero. im currently using a 12v 6 amp.
Sir is there any particular voltage led bulb is required for this or any led bulb 15 wt to 30 wt bulb is fine let me know sir i have same issue in my duck ktm 390 .im from India Bangalore
12 volt. 15 watt led would be fine.
I have excatly the same issue but the problem is that in my country it is illegal to change a regular bulb with a LED one and i wonder what i could other do to fix that issue?
How about a switch to turn the light off during daytime. That would not be legal in Australia though.
@@mostlymotorcycles. That is illegal in my country too, today i tested led bulb on a private road to see if that will really help and i didn't get any 0 during the ride
In the speedometer u have a secret switch that's for switching on and off the ABS system... Yes duke 390 have button to switch off the ABS
Thanks. Most Interesting.
I changed the stator but the speedo still shows 0 kmph at times. I even changed the battery but still no luck and my headlight bulb is stock.
So what might be the issue?
Sounds like a different issue.
Maybe a broken or misaligned picup.
Or a corroded connector.
What do you mean by pickup here?
And could you even suggest which all connectors need to be check for corrosion?
hey man, have the same problem, i think only u can help me, exactly the same issue on duke 125 2013, i tried to change speed sensor and tomorrow i will try to change phonic wheel, for now nothing, what is your opinion? just tried now to unplug the forward light and i still got the problem, (i noticed maybe that is less frequent without light but not sure if is only my impression, is possible turn light that are chineese? they have a small white light always on? )
What i can try? Thank you and good catch for your problem
Try charging the battery over night if u can.
If speedo issue improves or goes away theres probably a charging circuit issue.
@@mostlymotorcycles.
hi, thanks for the advice, I tried but still the same problem, I did the same test as you by putting the multimeter on the handlebars and doing the test with/without the headlight, it's not clear if it improves or not.
in my case there are moments in which it seems to mark for about ten seconds and then goes away.
but the voltage in any case it is always of 13.5/14 V when I am on the motorbike and the problem occurs the same, I put the multimeter cables on two power cables under lock and key in front of the motorbike as you did (I don't know if they are the same but I think yes), do you recommend trying to change the phonic wheel? Already changed only the elettronic abs sensor near. Is it possible that the phonic wheel doesn't transmit properly the frequency?
It's unlikely to be the problem as it's just a metal plate. Check the gap from the pick-up to the disk.
As the voltage is good I'm wondering if it's a fault in the gauge cluster itself.
Only way to know for sure would be to swap it out with a spare from a friends bike or something like that.
Otherwise I'm out of Ideas.
Worst-case would be if you bought a new instrument cluster and the fault continued.
@@mostlymotorcycles. Hi I have an update! First of all, thank you so much for your reply, you're really kind! I dismantled the fuse box at the back seat and found the 30a main fuse loose, but it still works. so I decided to change all the fuses and clean all the contacts, now the problem seems to have been solved, at this point I think I should do a more thorough cleaning of all the contacts.
the strange thing is that I had the new speed sensor mounted and as soon as I tested it on the road it seemed to do it (1-2 times) then it seemed to have stopped completely, I refitted my old sensor and now it really rarely does it, I don't know whether it can also center the sensor as well as the contacts! one thing is for sure, the problem has reduced exponentially since I changed and cleaned the fuse contacts
Most excellent.
Hi is have duke 390 2013 model if I go in 10 kmph it shows 01 in speedometer if go 100kmph it shows 10 in speedometer what will be the prblm
I am facing same problem, did you find solutions
No still facing same problem @@sanjeevbendigeri4010
No still facing same issue @@sanjeevbendigeri4010
Hello, I have the same problem at my duke 390 2014.
Please what was the final the cause of the problem please? 🙈
Thank you!
Speedo dropping to zero is low voltage related. Could be the generator or battery failing. Try full charging the battery and see if the problem stop for a while.
Thank you for answer!
Today I puted battery to charger, so tomorrow I will see.
But now I found some strange thing.. When I ride on motorcycle with switched off motor the speedo shows speed normally.
When I ride with switched on motor the speedo dropping to zero. 🤷♂️🤷♂️
So I think abs sensor is OK and speedometer too, but problem can be somewhere in electroinstallation and it can be hard to find it. 🙈
Hello!
The third secret button is turning on/off abs.
Two ground wires and two power wires fit to the dashboard. Probably, there was a bad contact in some connector, so 7 or less volts reached the dashboard. The stator of the generator is in perfect order. After all, at the beginning during the test run there were no reports of low battery voltage?! And the lamp didn't go out. Cleaning the green and black connector next to the dashboard helped me.
Thanks for the info.
