Do you want trouble stopped at the wall, or at your door? Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Test the energizer alone first. - Then isolate fence sections. - Common faults: vegetation, broken wire, insulators, earth. Quick answer Disconnect the fence and earth leads and measure the energizer output with a fence tester. If it is low (manufacturer guidance suggests below about 5,000 volts on many units) the energizer or its battery is at fault; if it is normal, the fault is on the fence. Then isolate sections with cut-out switches and look for vegetation, broken wires, damaged insulators and poor earthing.
