You'll need Acrobat Reader to open that file but the 4th page of that document has a good circuit, exactly what you are looking for. It was easy to find with my web browser and only the 3rd link on the page!

The link is broken

can you post a new or pdf?

Most good energisers have a 'weed burn' facility these days. A hundred meters or so of weed on your electric fence will cause problems, however you are correct in that when it rains this kind of overgrowth can actualy disable the fence.

I have heard of people using a ignition coil for an electric fence, the usual standard coils put out around 14 to 15,000volts HT.

As a kid (in the early 1950s) I once saw a man open the bonnert of a WWII Jeep then he placed the whole length of his arm accross the sparkplugs and kill the 4cyl motor. His arm jumped around a bit doing this. Now that got my attention.

This circuit uses a Car Ignition coil and works quite good.

But Yes, You Need Good Insulators on the Wire and the wire needs to be in Free Air.
Rain and Plants touching the Wire can Short it out.
