Need wiring on a condenser motor 1/4hp 1ph 1075 rpm.
I have a bad condenser motor and it is an AO smith 1/4hp 1075rpm.The factory motor has only 3 wires a brown purple and black. The wiring diagram shows purple and brown are going to a sep. cap and the black is the line. In the a/c unit the purple goes to the defrost control board and the brown to the capacitor and the black to the contactor. Now on the new motor ot is an AO smith with 4 wires,a brown,brown /white strip, a yellow and black. The wiring diagram shows the brown and brown/white strip are going to a sep. cap and the yellow and black are line. I think the brown and brown/white strip are going to the capacitor and the defrost board but I'm not sure if the yellow or black are used going to the contactor. Also if one is not used which one don't I use. Any help will be appreciated. Thanks:)
