I have a hoist motor that has had control wires pulled out and need reinstalling. motor only has 3 wires coming out of it which makes it impossible to reverse a winding. Have added attached wiring diagram. Any help would be greatly appreciated. Thanks

Red - Yellow you see 5.7 ohms
Red to Green you see 11.4 ohms
Yellow - Green you see 5.7 ohms.

That would make Yellow the common lead. The 8 uF cap goes between the Red and Green wires.
Power is applied between the Yellow and Red for one direction, and Yellow and Green for the other direction.
