KeithMartin Posted March 15, 2022 Share Posted March 15, 2022 Hi -- I had a bike shop replace the wheel/axl after I cracked the original one. The four contact points of the electric motor are hooked properly into the CPU. I've used the app to erase the flash drive, unplugged and replugged everything back in a dozen times, unplugged the battery connection, and held down the power button for 30 seconds. But no matter what I do, the CPU is not registering the new motor. When I run the diagnostic on the app, I get a red X by the motor. The unit also, when turned on, has a small red dot on the left, upper corner of the battery indicator. Nothing seems to work. Please help!

EIN5TEIN Posted March 18, 2022 Share Posted March 18, 2022 I had a similar problem with my V8F: the axle was cracked and I was having a sudden violent shuddering a few times in the last month before the wheel has finally started saying "Please, repair". Then I bought the new motor, connected everything properly, but the wheel would not power on, same red warning sign next to the battery indicator. The diagnostics was still showing the same "Motor Hall signal error". It turned out that those spontaneous shudders had in fact burnt the motherboard. Only after I replaced the motherboard everything started working, the diagnostics goes through without issues, the odometer is showing 0 km. )) 1 Quote Link to comment Share on other sites More sharing options...
