High brake vs 0v brake on svmc 72150

[okie]

I have an SVMC 72150, and it has both a "brake 12v" and a "brake 0v" wire. Do they want you to use both, or only one?

I have Magura Dorado e-brakes if that makes a difference.

I currently have them wired up to the "brake 0v" as shown in this diagram, but I'm thinking about switching to the 12v method because I want to power a brake light. I'm wondering if I do that, do I need to disconnect the 0v wire or just wire up the 12v wire right along with it?

Can't figure out if both wires are provided as an either or situation, or if you're supposed to use both of them simultaneously.

Hi okie,

You use only one or the other, not both.
Do you have an external 12vdc source?

I do, a 72v to 12v converter.

Hey, how’d you get the non-running and noise problem remedied?

It turned out to be a faulty hall sensor from the factory. I plugged into the spare hall bundle coming from the motor and that fixed everything.

Sounds great, well done!
