Greetings Denizens!, I'm building a small "zapper" for the purpose of keeping critters away from a deer feeder. Other than volts and amps ratings, I believe it is, for all intents and purposes an electric fence, just in a unique configuration (shape, not electrical specs - those are within the "normal" output specs found for DC fence chargers - similar to that of a dog's shock collar at around 2kv.) It will live outside, year round, year in, and year out. I never want to take it out of the field. To that end, I was considering the possibility that corrosion to the galvanized fence wire might reduce, or eliminate the effectiveness of the device. Does anyone have any personal knowledge, or know of a resource that can give me some novice-level information on just what I can expect? I could use stainless steel wire, but that does not come cheap. I also expect it will not be as malleable, and therefore will be harder to work with, in the small spaces I will be fishing the wire through, and wrapping it around. Another consideration - does Petroleum Jelly readily conduct electricity? I also have a chromed cage that will be the ground lead for the device. Eventually, I know it will rust. If I smear Petroleum Jelly on it, will it still be an effective ground? Thanks in advance for any help offered.
