BbsHD MAIN HARNESS DAMAGED

Post by Oscdav » Feb 22 2021 5:21am

Hi, I have had a complete power failure and discovered that the main harness at the motor end got squashed and badly damaged by being tightly trapped between the lower part of my bottom bracket and the motor itself after it hit a log at speed.
I need to source this harness section from here in Norway and renew it from the motor.
Do you think that the controller is fried and how do l test for this?
Also,where would be the best place to buy the harness section and controller from here? Your help would be much appreciated.
Thanks, Oscdav

its quite hard to tell what happened because the pics are bad quality. But in the first pic it looks lite the wire got squashed but left enough space to cut the broken piece out and solder the wires back together again. If there isn't enough space you could open up the motor and pull the wire out of the case, then solder it and put it back in. I guess that's quite easy and cheap

Finding that piece of wire would be hard. Maybe try posting in the Items Wanted section of the forum and try to find someone that has a fried BBSHD with a good cable.

I would just cut out the damaged section and solder the wires back together with heat shrink tubing around them and try it.

Depending on which wires made contact with each other, the controller may or may not be fried. One wire is carrying battery voltage and if it makes contact with the serial data line, it's toast.
