I have had a Super Lucky Duck spinning wing decoy for three years. I use it four days out of the year at most. Today I went to charge the batteries before I go to SD duck hunting and it won't work. After hooking up directly to the motor and not going through the switch I have determined the motor to be bad. The battery tests fine. Has anyone else experienced this with such little use? I called the company and they said I need to dry it out after every use. I have never had it in the water. Will the fall humidity do this? Just curious and don't want to spend $100 every three years on a new one. The motor cost $25.00 to replace.
