Please help with this circuit! Its not working and I have no idea why!

[Timmy Tucker]

Hi everyone. So the other day I came on here and asked for some advice on controlling the speed of a motor with a motor speed regulator. Thanks to all those who helped out.

It has now arrived but I am not sure how to connect it up. Can you help?

Here is a diagram of the circuit and the motor. I have written on the 4 connectors what they are.



So I plugged the cable running from the switch in to the + Power connector, and the cable from the motor in to the - Motor connector. The connection is complete but the control knob doesnt work. What am i missing? Have I done it right?

What happens to the - Power and + Motor connectors? Are they needed? Does something need to go in them so I can use control knob. What about the red cable in my diagram? Does that need to go back through the motor speed regulator?

Many thanks.

Tim

I'm sure we can fix you up with a better motor speed controller board than that......
