run speedwave 2640 without controller?

[lastlight]

I'm assuming the controller for my pump is to blame. For the past few days the pump has been turning off and then back on after a few seconds. Early this morning it turned off but did not come back on. The unit still lights up and responds to the pressing of it's buttons but the pump does nothing. The impeller assembly spins freely there's just nothing happening.

So my questions is, can I cut the power cables and connect the pump directly to the power supply? I'm assuming the brick is converting the AC to DC and not the little speed controller but I could be wrong. I already cut the wires and found only two exiting the brick and 3 entering the pump. One of the three appears to be a ground wire.

Red and white wires from the brick. Blue, red and a green/yellow entering the pump.

I don't trust this thing for regular duty and have a mag 18 running in its place. I would however like to use it for maintenance jobs like pump new sw into my sump etc when needed.
