Morgan Posted August 11, 2016 Share Posted August 11, 2016 Hi all, My nephew lost his balance while learning to ride my wheel along a wall, and hopped off. The wheel kept going and got wedged, so that the unit was tilted forward and was still trying to turn, but couldn't. Now when I turn the unit on, it works, but stutters wildly (video attached). The wheel feels and sounds normal when spun or rolled with the power off. I'll open it and have a look when I get a chance, but wonder if anyone has seen this symptom or has any ideas.

US69 Posted August 11, 2016 Share Posted August 11, 2016 so the wheel got stuck and tried to move on? then perhaps something on board has burned...mosfet? sounds like you need a new board...my 2 cents Link to comment Share on other sites More sharing options...
Morgan Posted August 11, 2016 Author Share Posted August 11, 2016 Thanks KingSong69. To clairify, the unit was still upright when it came to rest so no auto shutdown, but wedged under a lip on the wall, so the wheel couldn't turn, though it was definitely trying to. I managed to shut it off within 3 seconds. Link to comment Share on other sites More sharing options...

Morgan Posted August 11, 2016 Author Share Posted August 11, 2016 Okay, no sign of burning on the motherboard or wires. Are the MOSFETs built into the battery packs? Any way to test them? Link to comment Share on other sites More sharing options...
EUCMania Posted August 11, 2016 Share Posted August 11, 2016 This is a common problem, but the fix is easy: The board or the side panel is lose be cause the screws are not tightened now. Then the board is shaking, making the gyro thinking your EUC is shaking and hence reacts to counter the shaking. Just open the side panel tighten all screws. It will work again.

Morgan Posted August 11, 2016 Author Share Posted August 11, 2016 Thanks EUCMania....I wish the solution was that simple - the board is perfectly secure. It does seem like a lazy gyro though - as I tilt the wheel the motor doesn't smoothly and immediately react, but pauses, then "jumps" to keep up.

gobygoby Posted September 14, 2016 Share Posted September 14, 2016 I have an iWheel that is exhibiting the exact same problem. The motherboard is very secure, so I do not believe it a loose sensor. I am guessing the problem is coming from the motherboard and not the hub motor, but I'm not positive. Any updates on this issue? Link to comment Share on other sites More sharing options...
Morgan Posted September 14, 2016 Author Share Posted September 14, 2016 Awww...sorry to hear that. The unit is currently on it's way to the mainland to (hopefully) be repaired. I suspect the motherboard will need to be replaced, but will post an update here as soon as I know something. Link to comment Share on other sites More sharing options...
Bay Surfer Posted September 15, 2016 Share Posted September 15, 2016 Easy way to check if it is bad mosfet on the controller is to unplug it from the motor/wheel, if it turns smooth unplugged its a bad Mosfet on the the controller. Hope they fix the wheel fast. Link to comment Share on other sites More sharing options...
