It says I should swop over the two wires that feed the commutator as shown in the article picture below;

But on my motor there are THREE wires, two to the RHS and one to the LHS as shown below

Do I still swop them over ie move the two wires to the left and the one to the right?
The single wire appears to be red/green and the two wires appear black with a white insulation inside.
