Sometimes, the connections and wires from your energiser to you earth stake and on to your fence can get damaged. This can happen because they have been tugged, due to chemicals in the environment sprayed in local fields, and due to age. It is essential to have a good connection from your energiser to your earth stake and to your fence.
These leads work for the Horizont Trapper AN8, AN12, AN24 and the Hotline Gemini 40, Gemini 80 and Gemini 120.
You can also use high voltage lead out wire (for any energiser). Simply remove a section of the plastic coating at the end of your wire, and wrap it around the energiser terminals and the fence/earth stake.
