Earlier whenever i used to reverse my ebike manually it used to not give me a drag but but after checking it for any issues using the ebike testing device, I taped all the wires together(I guess shorting all of them in the process). Now i think i have a issue where it is giving me huge drag when trying to rotate back. I have also got a 03 error on my display caused by hall sensors after giving a grinding noise from my motor.
Is there any linkages within the two and how do i troubleshoot the two issues?

Thanks in advance, Cheers!
