I made a picture of my Canable and how I have my wires connected, I also did a continuity test from both ends (male to female) of the wires and that was positive. I also did a continuity test between the female connector and the Wago/Canable and between the male connector and the Wago/Canable.

First I connected all the cables like in my picture (see here) without connecting the Canable to my laptop and after that I switched on my HMI display. The moment I connected the Canable to my laptop with it’s usb cable the HMI display went out and by unplugging the Canable from my laptop I was not able to power on my HMI display and when I measured there was no voltage between the Brown and Black wire and at the beginning when I started there was a battery voltage (I believe it was 36V or something, battery was at 70% when starting the experiment)

I have no idea if that is normal behavior but after that I was just unable to power on my bike and now I’m not really sure how or why it eventually worked again.

I’ve got my bike a few weeks now and I’m not so fond of trying it again. What I just found out is if you remove the existing HMI and replace it with a 600C HMI then you are also able to change the speed limit and that display gives more info while riding the bike. Maybe that’s a more secure way. Topic is here.
