I found a used Warn Powerplant for sale and know nothing about them except they seem to be a winch with a built in compressor that runs off of the winch motor. I can see this as a useful tool, but have never heard of it. I am hoping someone can tell me if it is worth $400.00 or if I should just keep looking. It appears to be in good shape, but it has had the wires cut off that will have to be replaced and that also means I can't tell what is or isn't working. Any insight would be appreciated.
