Bypass the controller on a DC pump?

I've got a spare Jebao DC12000 controller if you need one.

Curios about this as well. My DC-10000 controller has also packed it in. I'm running a smaller emergency pump while I try to sort it out.

I'd buy a new controller if I could, but no joy from RLSS, the distributor.
