Leionar27 Posted February 19, 2021 Share Posted February 19, 2021 Hi guys, I'm asking ur help, my ks 18L was really dirty inside the shell and I decided to clean up a bit. So I followed this method in this topic https://forum.electricunicycle.org/topic/7401-small-trick-for-cleaning-your-acm/ I attached a soft cloth to the wheel and started to move the wheel with trolley. A lot of mud and dirt came out the wheel, so it was perfect until cloth started to come off the wheel, and it blocked totally wheel's spin. But I forced with to move it with trolley cause im stupid, it cuts off 4 times before I had the presence of mind to shut off manually... It still turn on when I push power button but Im a bit afraid to ride it now. Do u think I damage something and it has more chance to fail me during rides now? 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Scottie888 Posted February 19, 2021 Popular Post Share Posted February 19, 2021 (edited) Did you do something wrong? Hmmm IMO yes & no. No because you're correct in pulling out the shell & doing a clean. Infact its recommended that we do that occasionally to not only clean but to inspect & ensure no loose connectors, nuts/screws are tight & that everything is where it should be. Yes you screwed the pooch in forcing the wheel to keep running when its blocked. The reason why it cutout was cos it was overloaded trying to spin when it couldn't. Luckily that cutout is a safety mechanism to ensure no damage is done to the electronics & motor. Since it can turn on, its likely the mobo didn't burn any components. If it passes the no load spin test, its likely fine & ready to go but if it were me, I'd try riding it slowly to test it out initially. Even if it cutout again, there'd be very little damage to either machine or man (hopefully). However its my humble opinion that your wheel is a-ok.

Popular Post Leionar27 Posted February 19, 2021 Author Popular Post Share Posted February 19, 2021 Thanks for ur reply and welcoming Scottie888. Thats reassuring, I dont know anything in electronics and I started to read that mosfets ( and fuses ? )can be damaged when u overload a wheel in low speeds. 4 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted February 19, 2021 Share Posted February 19, 2021 (edited) Sorry, I feel responsible for this! I added a big disclaimer to only do this kind of cleaning while the wheel is off. If your wheel is still working, I think you're safe. The 18(X)L has fuses (I believe) for exactly this kind of situation (blocked tire level of stresses), so if the fuses didn't blow, that's a very good sign. The wheel just told you to stop early enough. You can do a few pendulums (not too crazy, pendulums put a lot of stress on the wheel, just like 10 seconds) if you want to reassure yourself. If anything were close to failing, it would fail then, and with no crash to you. So you'd know. But you should be good. Sorry again. Also, this is what full face helmets are for. EUCs could always have a hardware failure, even if that virtually never happens in real life. The helmet is everyone's insurance for the tiny bit of uncertainty left.

Thanls for reply and dont be sorry, fault is mine. I just didnt attach well cloth on wheel... I will try a few pendulums, thanks for advise Quote Link to comment Share on other sites More sharing options...

It could have gotten stuck on some dirt, too. The point is to never block the tire of a wheel when it's on. Because naturally that might fry the electronics as they try to counteract the blockage.

Just take it as you're Sylvester da puddy tat with nine lives. So far, you've only used up one of em so there's still a few left spare. That said, I would do my best to not repeat them😜 3 Quote Link to comment Share on other sites More sharing options...
