I am trying to install an electric fence for an arena. My problem is that the arena floor is ground rubber mixed with sand. I am using 1 inch polytape and a 2 mile solar energizer on a 60 x 90 arena. I was told by Tractor Supply Company to connect one end of the tape to the positive terminal and the other end to the ground terminal of the energizer and that would work. It didn't. Any suggestions to get it to work?
