This video helped a lot. Thank you. Stupid business here in NYC that sells scooters don't have mechanics that knows how to fix them. They only fix the electric bikes / mopeds.

Thank you, I'm back on the road thanks to you !!!

Hi Tony, thanks for guiding us on the repairs. I changed the battery and it was blinking blue, but it continued to give me the same error as before (red wrench display on screen). Would I need to change the computer itself? Or it could be something different? If you have encountered this issue, would you mind guiding me on this? Cheers

Just asking but normally with the red wrench there is an error showing up briefly (it even beep) If you get this error number (or get it on the app) try searching what the error code it connected to (for exemple, it can be the throttle that got water damage and is giving error, or some component that have moved and causing an error)

我有个SEGWAY NINEBOT S 平衡车， 其实是GOKART PRO， 现在按电源没有反应，充电也没有反应，反正无法开机，插上充电的时候充电器一直是绿色亮灯。我把电池拆下来， 电池上面的LED灯是蓝色一闪一闪的， 电压测试也是59.4，估计这个电池没问题， 但是我又把电池装回去后，按电源键，就BEEP一下，没有任何其他反应，和断电了一样。请问大概是哪里出问题，谢谢。

这个不太好判断，原因多种。 单从电池方面，既然打开了电池，那可以测试一下单节的电压，看看一致性。 另外我记得s的电池应该是15节，满电在63左右，你可以在开盖的情况下观察一下充电的时候电池内部指示灯有无变化。

@@user-gr4cl1jq9e 这样的话要分析就比较麻烦了，没代换配件的话只能分步检查。如果说每次装上电池按开机都有一次BEEP的话，那证明电是通到主板的；有条件拆机的话可以用万用表测一下。另外印象中S的开关机控制键是在蓝牙板上，通过线缆与主板连接，所以有条件拆机的话，这部分连线也可以检查一下。
