Lol,, now I`m confused,,
You should have kept the original cap where it was,with the compressor tied to it
You only remove the cap wire/wires that went to the old fan motor
When you bought the new motor they should have sold you a new cap. That was for the new motor only
The new cap. Was to have the br/br-w fan motor wires connected to it only
Hope you didn`t can the original capicitor,, the compressor needs a different megiferit capicitor than what the new motor needs
Look at the tag/label for the ac unit see if it tells you what cap. Is needed for the compressor
