To reverse in the schematic i posted earlier we may assume the right lead is neutral.
Then the left lead is fase.
when you move the fase wire to the top the motor will reverse direction.
You should check what i am saying next.
In the picture you posted i think the motor wires are all on the bottom row.
Starpoint of the motor is hidden.
Did you draw in green where the actual capacitor is ?

In its original wiring, it runs counter-clockwise as I face the shaft.... I can get it to run clockwise by rotating the bus bars through 90 degrees BUT I have to also move the Cap from pin2 to pin4 which seems odd and I don't have enough pins in the tumbler switch I have in order to implement that.
I was hoping an expert would reveal how dumb I was and say something like "you reverse it by moving the cap only"
I did, I don't know much about AC motor schemes but that motor looked (and sounded) like a different beast to mine.

Or this....?
We are seeing this from different perspectives my good man
I have a very poor grasp of the underlying/fundamental functions of the varying flavours of AC motors
If this image represents my conundrum, it does so in an abstract that I am struggling to convert into pin numbers.
I don't know how I get four pins from the three nodes

Ah... wait a minute... the three sets of two pins...
My apologies Bert.
I think I'm gaining some perspective, I need to have a ponder on what is going on.

Haha yes last 2 pictures work for me.
There is no real difference.
effect is the same.
The bus bars i am not sure of until we know where u1 v1 w1 motor wire go.
What is confusing in the picture is what wires are capacitor and what is the power cord.
Normally motorwires are all below the busbar no need to mess arround with them.
looks like u2 v2 w2 starpoint is hidden in this motor.
Grtz Bert.
