The light in the button on my Vision Spinner II won't turn off. When I put my tank on the light turns off but when I press the button the light flashes three times and then stops. It also doesn't burn the coil but I know It's not the tank Cause It works on my other battery and the tank worked for about two weeks before it stopped, and I know it doesn't need to be charged because I tried charging it with multiple chargers. Help me out here.
