I need to test whether there is a break in our electric dog fence. It is a buried 18 g solid copper wire that is about 600 feet long.
Can I test whether there are any breaks using a flashlight bulb and a 1.5 volt battery (i.e., does the bulb light?), or is there too much resistance in a wire that long for such a small battery?
Any other easy suggestions?
Obviously, I don't do too much electronics. I don't have a multi-meter or anything like that.
