So my brother fell of my bike. It's now not working low and high flash together also I'm not sure if the sensor near the crank is in the wrong place as it moves around . All the wiring looks secure and have checked this. Can someone check where this sensor goes and any help appreciated . Thanks. It's also out of warranty.

Hi. The hi+ low flashing lights on 790 unit means there is something wrong with either the brake switch or its wiring or brake lever not sitting back properly. If you cannot visually see anything wrong, trace the cable from each of the levers to connector and disconnect one at a time, starting first at the side that hit the ground when bike fell over. The bike will work with these disconnected. Reconnect the working one but leave the faulty on disconnected for now if this is the case.
The sensor need the crank ideally needs to be tightened up at some stage.

If you can't fix it, you can disconnect the brake switch as a temporary method, or even as a permanent measure if you have a switch on the other brake. You only need one. Follow the cable from the brake until you find a connector.
