Step 2: Reassemble the Zapper
Reinstall the ceramic spacers and the outer zap screen, with the screen's former electrical connecion spot near the disconnected wire. Resolder the electrical wire to the outer zap screen. Make sure your zap screens are oriented straight and concentric with one another, then reinstall the bulbs. Put the outer protective plastic screen back on the machine, and the top cap if that was also removed. Plug in the zapper and make sure the bulbs light and that there is no electrical arcing yet within the machine. Do a zap test by securing a small wad of paper towel to the end of a WOODEN OR PLASTIC stick with a rubber band and moistening only the piece of towel. Poke the stick in through the first zap screen, and you should get a zap. Unplug the zapper and DON'T PLAY WITH IT.
Hang the zapper somewhere outdoors where it will not attract mosquitos to where people might gather, up where it cannot be reached by people or pets.
