I have a Warn XT9000 on my 40. It free spools fine, it power unwinds fine, but when I try to power in I just get a clicking sound (similar to what you here when you have a weak battery on an engine start or a weak ground. I'm using the remote attachment. I've taken the ground terminal off the winch and cleaned that connection. I am assuming that if the system is working on the unwind then the power requirements should be there for the wind up. What other suggestions do you have for me to try before I have to get a professional involved?
