Need Help Identifying these wires:

Picture attached, a man at a local shop informed me that the orange and yellow wires that are connected (as seen in pic) are the reverae wires, and that once disconnected, will cause the motor to run counter clockwise.

Is this correct?

I am not sure about that. Normally with 3phase motors, forward and reverse is done by switching polarity of positive and negative 3 phase cabling. The cables are smaller gauge than the 3 phase ones so may be something else, like suppression filter connection.

If you post the make and model then we should be able to find a spec sheet for it.

Normally with a PSC motor there is three wires, one of which is the common for the other two.
The common being the N and the outer two have the capacitor connected across them, input L1 to either of the outer ends to reverse.
This is only as long as both windings measure equal resistance.

Thanks for the response, what you described I currenly have wired.
So, if I take l1 (red, low speed) and put it to either side of the capacitor, it should reverse?
Can i run l1 to capacitor, and then back out to an outlet for power?

So, on the side of my motor its mentions the orange and yellow leads.
As it says, plug yellow into orange for cwse, and orange into orange for ccwse.

My question: There are two yellows and two oranges.

To turn the motor ccwse, do i only need to plug orange into orange thus leaving the two yellows detached? Or do i need to plug the yellows together as well?

You will notice that the fact that two of the wires have male connectors and two have female connectors. This means that when the yellow wires are connected to the orange wires they can only plug together one way So the Yellows will go to the correct oranges. I believe that when the orange wires are connected together that the yellow wires will also be connected together thus reversing the polarity of one of the windings. It would have made things much easier if you had posted a full picture of the information on the motor in your first post. even now you have prevented us from seeing the full lable with the information on. When you let us see the rest of the lable we will have a better idea of how the windings are arranged. We may even then have to get you to measure the resistances between the wires.
