Your tester if it is the type that you just touch it on the wire will show you that your fence is working but if the ground is too dry it won't show that. The old type tester that has a probe in the ground and the hand piece touches the wire and various number of lights show up depending on the strength might be more appropriate in your case Murray to see if the ground is too dry to give a shock. Those testers are very cheap, often given away with other gear.
