Help needed Motor does not run

Hello,

I'm attempting my first E-Bike build and just finished the wiring. Unfortunately not everything works right away. I hooked up all the connectors to my Infineon Controller, the switch to power the system up works, as I can tell by the CA also working. When I turn the throttle the motor does not respond. I use these components:

Mac 10T (cassette)


I have a multimeter and this tool:

How should I proceed, to make everything work ?

Thanks
Felix

Are you using the CA to control the throttle, or direct throttle to controller?

Unplug the CA and see if you get power. Then you know it is to do with the CA settings. Not much help, but an easy place to start

It's directly pluged to the controller.

Thanks, will try.

There are several things that can make it not run.

Brake switch activated
Hall sensors signal invalid
Battery voltage too low
Throttle signal bad

And probably a few more, but you can eliminate these one by one with testing. I would try unplugging the brake switch wires too, as these are not needed to make the motor run.

Minimum battery voltage is programmed into the controller.

Thanks, that was it. I thoughtlessly mounted the brake sensor without mounting the magnet.
