Giovanni Posted March 26, 2019 Share Posted March 26, 2019 Dear riders and KingSong representatives! Maybe somebody can help me to diagnose and understand what is the issue with KS-18L? You can see everything in the video: my EUC was charging and I just started to rub and wipe it with paper napkins, suddenly I heard regular beeps (every 2-3 seconds) and when I turned it on I saw unusual red LED indicators (1st and 9th from each side). The problem is floating, it's difficult to cause it again, but it happened already few times with my KS-18L. After turning off/on everything is OK and riding is normal without any troubles. Does anybody know what is the issue and what do that red LED indicators and regular beeps mean? videocompress-016-VID_20190323_150410.mp4 Quote Link to comment Share on other sites More sharing options...
Marty Backe Posted March 27, 2019 Share Posted March 27, 2019 @US69, any ideas? Quote Link to comment Share on other sites More sharing options...
RockyTop Posted March 27, 2019 Share Posted March 27, 2019 It kinda acts like that when you lock the wheel and try to walk away with it. Quote Link to comment Share on other sites More sharing options...

US69 Posted March 27, 2019 Share Posted March 27, 2019 @Giovanni in the both latest apps under detailed parameter you have some failure messages. is there any message shown? Or all all parameters normal? (While the fault is there...and also in general?) Quote Link to comment Share on other sites More sharing options...
Giovanni Posted March 27, 2019 Author Share Posted March 27, 2019 @US69, thank you for quick reply! No issues in general reported by KingSong apps (attached screenshots from both old and new apps). Regarding app report while the fault, it's not that easy, because this problem is floating, appeared only few times and I can't cause it on purpose.

Giovanni Posted March 27, 2019 Author Share Posted March 27, 2019 @US69, I have also asked previously community of Russian EUC riders in Telegram about this issue. They said as well that they know different LED combinations, but not this one. And I think they also asked KingSong about this and answer was to look if app reports any issues while this fault appears. Another interesting thought was that maybe it's static electricity causes this problem, another Russian rider has also experienced same LED combination and beeps and his guess is static electricity. I believe that's really can be the case, because it appeared while I was wiping and rubbing my wheel with paper napkins and wheel was charging at that moment. I haven't noticed any other problems with my wheel, except only 2-3 times when I turned it on green LED indicators weren't switched on, it happened after I had turned on/off hese LED lights few times in KingSong app. 1 Quote Link to comment Share on other sites More sharing options...

As said, i have asked KS contacts, its just that its now 21:30 in China.... So waiting for an answer tomorrow here. And also: Yes, Maybe your whiping triggered the well known "static electricity" glitch, which then, other than while trolleying, while charging triggers the LED fault message.

Giovanni Posted March 27, 2019 Author Share Posted March 27, 2019 (edited) @US69, ok thanks! Just one correction, I am not sure if it was combination of first and ninth LED, first for sure but as for lower LED I don't think it's ninth, it should be above, it's visible even on low resolution video I uploaded here. Next time (when and if) it happened I will check it. Also I asked in the Telegram chat and we have at least 3 riders with the same LED and beeps symptoms as you can see on my video.

(while i still think it is the wipping and static Energy) 16 minutes ago, Giovanni said: Also I asked in the Telegram chat and we have at least 3 riders with the same LED and beeps symptoms as you can see on my video. Then it is for sure the "static Energy" Problem, as this is the only known Problem on the Wheel.......which at least only happens when the Wheel is stationary or only on trolleying. When i might ask for a favor: The KS contact has Problems to watch the video-Format. Are you able to reproduce the Problem and throw it into YouTube, perhaps? Also: Will contact/Mention you as soon as i get an answer :-) Quote Link to comment Share on other sites More sharing options...

Next time (when and if) it happened I will check it. Looking at the video, I didn't think the lights are 1 and 9, so I grabbed a couple of frames and overlaid them in Photoshop... It's a little rough, but with the key points lined up it looks like this is 1 and 6! @US69 - what would that mean? 1 1 Quote Link to comment Share on other sites More sharing options...
RockyTop Posted March 27, 2019 Share Posted March 27, 2019 (edited) I should just be quite while the adults talk but are you supposed to count the lights starting from the top? Edited March 27, 2019 by RockyTop Quote Link to comment Share on other sites More sharing options...
Giovanni Posted March 27, 2019 Author Share Posted March 27, 2019 @RockyTop, you can see almost all of them (except second and third), so it's not a problem to find out it's 1 and 6. @The Fat Unicyclist, thank you very much for Photoshop detection) 3 Quote Link to comment Share on other sites More sharing options...

Thanks in advance Giovanni, i really, really would like to have the total effect on a youtube video...wiping and then LEDs go red.... That telegramm video: That look like LED one and five, which is motor short circuit. Led one and six would be Onboard gyroscope error. Hearing of the wiping its more and more clear that -whatever the LEDs say, thats the case of static electric energy. So actual there is no real solution to this problem of static energy, i would suggest just not to clean it while it is charging. Sorry, i REALLY know it is frustrating to have such a stupid error, i can only say that worldwide never something happens while driving.... Just Another thing: Please, Giovanni, can you please in the future only do links to video files? The forum software only provides a very very small memory space for each member, and posting videos ON the forum, without link, would fill up your memoryspace anyway....(its also in the forum rules ;-) ...and a moderator might delete them)...Forgot to say that in my first answer....WHEN this are links allready...excuse my stupid me. 2 Quote Link to comment Share on other sites More sharing options...

Both videos (I posted here) started after this issue (red LED and beeps) appeared, so in the video you won't see wiping/rubbing/cleaning or anything else that had happened before and caused this issue. The problem is you never know when it will appear, so it's difficult to shoot video from the very beginning, also I can't reproduce and cause again this issue, I tried really hard yesterday wiping my wheel with paper napkins) and nothing happened... If I get these beeps and red LED again, I will try to film it better. However it's only our guess that wiping and static electric energy causes this problem, maybe that's not the case. 22 hours ago, US69 said: Please, Giovanni, can you please in the future only do links to video files?

Led one and six would be Onboard gyroscope error. @US69, where is this information available, about different combinations of red LED and beeps and its meaning for malfunction diagnostics? I tried to search and couldn't find it, it's also not present in the wheel manual.. Edited March 28, 2019 by Giovanni Quote Link to comment Share on other sites More sharing options...

Vincencus Posted September 2, 2022 Share Posted September 2, 2022 Hi Giovanni, Did you find an answer/solution to this? My 14S started doing this a few days ago and haven’t been able to do anything about it. Quote Link to comment Share on other sites More sharing options...
