This is to replace the second ballast off the BK-80, not the transformer/first ballast assembly. Always unplug the unit and take proper safety precaustions. To replace, remove the screws holding the ballast in place and disconnect the wires running to the bulb socket. Screw in the new ballast and reattach the wires to the socket.

These spare parts are for Flowtron bug zappers. We do not know if they will work for other machines.
