Yup. Like I said I had installed a switch on the power wire of the receiver, I was worried that it might catch a wireless signal somehow like from another remote or something, and as soon as I switched it on to start winching the thing started winding itself in without pressing any buttons.
It was just a cheap chinese clone one from amazon though so the XBull one might be just fine but it put me off that style of wireless receiver. I just use the wired remote for that winch now.
