Horse people, help me out!

So I need some help with you Horse People out there. Last year we installed Hot Tape for our cross fencing. Well since that time I tore down the overhang on our barn, so I needed to move the charger box for the fence.

I re-installed new ground rods, and I don't know if this reading on the fence is strong enough. We have the 3 mile charger, and I'm 99% sure the install is correct, but our reading seems low to me.

Let me know what your reading is... I don't want to zap the horses too hard, but I want them to respect the hot tape. I'm thinking we might need to buy a 5 or 10 mile charger box to up the zap?

Please leave me a comment if you think this looks wrong, needs to be tweaked, or even looks right.

Thanks!
