I can do this but I need a schematic of the reversing switch as well. On the wiring diagram, low voltage puts the two run windings in series, high voltage puts then in parallel. As you rightly say, you change direction by swapping the polarity of the start winding, so you need to arrange the forward/reverse switch to swap T5 and T8 over. I assume the reversing switch has a centre off position. Incidentally, it is immaterial , but I do not recognise the symbol to the left of the thermal trip at the top of the drawing, just under the letter L in "Line" Anyone enlighten me?
