Electric fence: is it on or off
I posted a while back about fencing most of my yard off
and letting a neighbor's cows keep it cleaned off for me.
My neighbor supplied all the fence material, and I put up the fence.
It is an electric fence. It is entirely in the flood plain of the river.
So sometimes he turns off the section that goes to the river.
So, except for actually touching it to find out (that hurts),
how can I tell if it is on or off at any given time.
I'm sure I could buy some kind of tester.
But I just need a simple (cheap or free) method to test it.
