Ive had to go behind someone's work. Im trying to figure out how to wire a cooling fan. Coming from the unit is 3 wires. Two of the wires one brown the other purple are coming from the capacitor. The 3rd is black coming from the contactor. Coming from the fan is a black, white, brown and brown and white. Also the old fan was disconnected while the power was on. Sometime from the disconnection t my arrival the wires have made contact and the board has 3 burnt connections. Ive already replaced the capacitor because it was swelled. The contactor is clean and emitting the proper voltage. Before I replace the board Im going to check the compressor for continuity. But the fan is the biggest problem for me right now. Any advice is appreciated. Thanks
