Hi all,
I am new here. I put together my own eBike last spring to be able to transport myself a more safe way during Corona. I bought a Bafang 750W mid drive kit. Have worked pretty well, but have had some problems that I have solved.
Now I have a new problem. The display turns on, but no sound or anything from the motor. I disconnected most things and when disconnecting the speed-sensor from the rear wheel it, it started working again! I had a spare, so I changed to that. But when later trying the bike it had the same problem again. Tried and tried. Disconnected speed sensor again, all brake sensors and throttle, but nothing. Then suddenly it worked again. But when I stopped it was the same problem again. Tried several times, then it worked again, but as soon as I stopped, it again took several attempts to work again.
Now I am thinking that maybe it is some moisture in the cables or something that makes it believe that the brake is activated? I had a serial cable that I had not used before, and connected that to my PC and downloaded the Bafang Configuration Tool. I had hoped that it would show the status of the ebrake. But it does not. Is there any diagnostic software that can show this? I know some displays can show this, so the controller should be able to tell the computer.
