The green Sense-Alert light on the zapper is the contact light. That means that if your zapper has a bright green light, you have a good contact with your zapper. If the green light does not light up, then you may have a faulty or broken wire, insufficient moisture in your super straps, or your wire jack is not properly seated in the zapper.

Solution: You can test for a faulty wire. Turn on the zapper and plug in the cable. Touch both of the snaps (or alligator clips) together. The green SensAlert LED should light up. If it doesn’t light green then the cable is probably at fault. To confirm this, please use the second cable we included with the AutoZap.
