The Electronic Spark Suppressor is intended to improve lightning protection and does the same job as the output board on the New Zealand power chargers. It takes out the extra high voltage spikes in the pulse which causes undesired sparking. Voltage over the normal fencer output voltage is shorted down. There should be no load on the charger at 5000 volts. Hook one wire to the ground terminal and the other wire to the hot terminal of the charger. This unit is much easier and less expensive to replace than repairing the charger when lightning strikes. (For outdoor use, see MSW weatherproof spark suppressor)
