Already contacted support but thought I may as well ask here. I just got my Roadrunner S3 in the mail and straight out of the box after assembly and battery charging the display gives me the E3 message indicating a problem with the hall effect sensor. I'm not sure where to even begin with this. I tried looking at cords under the seat and they appear to all be plugged in, but I tried replugging all the ones that weren't caulked into place with no luck.
The throttle has some loose (colored cables exposed from inside the black rubber shroud near the housing of the throttle) looking cables but I don't think that is the problem since if it's cables were broken I don't imagine the screen would turn on at all.
Also there was an Oreo wrapper in the box which I thought was funny but probably isn't the problem haha.
