LED Indicator Problems & Flasher Relay?

[duncanmiller]

Hi Guys,
Anyone reading my previous threads will see that I am having problems with the indicator flashing rate after fitting front led indicators. Also I cannot find a flasher relay? The wiring diagram does not show one? I could have probably resolved the problem by fitting a flasher relay that copes with both kinds of indicators (these are available). This bike does not seem to have a flasher relay, is the flash rate controlled by the ecu?
If anybody has found a led indicator that works at the correct flash rate, please let me know. I think someone said that Oberon bar end indicators worked at correct rate? I do not want to fit those as I wanted to fit Acerbis hand guards, but maybe the normal fit Oberon led indicators may be an option
Any help/advice greatly appreciated.
Regards.
Duncan.

Have you tried them with the bike running? When I installed my Oberon`s, they flashed really fast with the bike not running. As soon as I started it for the first time they were fine...

Hi frique,
Thanks for your reply and advice. I tried the indicators with the bike running and they flashed at exactly the same rate ie far too fast. I am puzzled at how the flash rate could become slower with the engine running though as if anything the voltage would be higher, which is more likely to make the flash rate faster with the engine running! strange. If I thought that the stalk mounted Oberons would work I would try changing for Oberons. Any further advice guys?

Duncan.

Hi,
as far as I know you can't repalce the flasher relay by itself at the Hyper.
I used a 47 Ohm / 11W resistor for each side with good results.

Modern Ducatis (and cars) don't have a conventional flasher. The blink rate is controlled by the dash cpu. The blink rate change is used to indicate that a bulb is out (by sensing low resistance). Using a resistor will fool the cpu into blinking correctly.

Thanks for the advice, I thought there was no relay, you guys have confirmed that. Next question has anone fitted front led indicators that work right straight off with the correct flash rate? Do the original handguard led indicators have built in resistors? Do I need to fit resistors to get the correct flash rate with alternative led indicators? Also can using resistors overload the dash cpu? I await your advice.
Many Thanks,

There was a thread posted a while back and supposedly, you can reprogram the flash rate from standard to LED. This is for when you replace the rear flashers with the DP LEDs. I tried to do it, but could not get the setting to store when I closed out of the program. It would always return to the faster pace. You might want to see if you can find the post or talk to you service rep to figure it out.

If that doesn't work, Motrax makes a set of relays that are splice inline and it cures the problem. I believe they are made on your side of the pond.

Good luck, let me know if you figure out the reprogram feature.

Out!

Hi Axe,
thanks for advice. The Motrax device you refer to is I think the flasher relay they make that corrects flash rate when led indicators are used. This of course cannot be used as the Ducati we know does not have a flasher unit. You can get resistors that splice between the + & - wires to the led indicators. This could well resolve the problem although a bit messy as resistors have to be kept away from anything damaged ny heat & are recommended to be fitted to a metal surface so they can dissipate heat. This is a possible solution although I do not know what rating of resistor I would need. I am wondering if the original Ducati handguards have resistors of some kind built in as standard. It seems strange that there is such a large difference in flash rate between the Ducati led's and after market led's?
You can now get led indicators with built in resistors, these also might work but I am a bit worried that if you put too much resistance into the Ducati dash cpu that you could cause some damage to it? I am not sure about this.
I never thought it would be so difficult to swop indicators!

Hi Guys,
Further to my previous posts on this I tried reprogramming the Indic menu in dash. I achieved this, basically when you access the indic function on dash, you toggle with the a/b switch till the indic menu reads Lamp (this is the default setting) or LED, to lock this in memory you hold switch down in position B for a few seconds until the display reads non (think thats what it reads from memory) the setting is now changed. Next the annoying bit!!!!!!!! when I tried the replacement front LED indicators (non original as the whole idea of this was to swop hand guards), If I use the standard lamp setting on menu the indicators now flash very fast, If I use the LED menu setting the indicators now flash even faster. I have tried 2 different makes of LED indicators and both have the same flash rate problem. I have also tried using resistors (supplied with one of the sets of indicators and rated at 10w) with the new front indicators, still a problem, if using resistors, the indicators do not work at all whatever the menu setting. I have now deduced that the original LED indicators that are fitted into the handguards have a higher resistance than other replacement LED indicators, so obviously the answer to this seems to be resistors of a smaller resistance then the 10w ones supplied with the set of replacements I bought. The trouble is I do not know what resistance I would need, if anyone out there can work this out please let us know, and also if possible where to obtain them. What may work, and I have not tried this yet would be to replace all the indicators front and rear for LED type and reset dash to indic LED. Never thought it would be so difficult just to change a pair of indicators.

Resistors have mine working perfectly
