How an electric fence tester works

[drplokta]

1. Stick the earth spike in the ground
   
2. Loop the metal bit over the fence
   
3. Squint at the LED in the bright sunlight
   
4. Put your hand over the LED to shade it enough to see if it's flashing
   
5. Get your hand zapped with 3,000 volts
   
6. The fence is working

When I was very much younger than I am now, I went to a Scout camp in a field in Yorkshire next to the River Ouse. There was a fence along the river bank which we discovered was an electric fence. No warnings, we discovered it by touching it. And of course, boys being boys, once one discovered it, other unsuspecting boys were directed to discover it for themselves. Oh what fun.

(To date this event, I remember sitting in a tent whilst someone was playing a small transistor radio listening to England beat West Germany in the World Cup final.)
