Having trouble with something killing pheasants. Put up two strands of electric fence and hooked it up There's power to the energizer, the light is flashing on and off. Tested with a piece of insulted wire and it sparks. But just a small spark. But the cats are weaving in and out of the wire with no shock. Dogs seem to be brushing up against it, no shock! We used the same emergizer last year to teach the rat terriers to leave the keets alone worked great.
