Fault finding with a Voltmeter

The best way to track down any faults in your fence is to use a digital voltmeter.


Faults may occur in either your energiser or on the fence line – a voltmeter is the best tool to assist you.

To test energiser.

Disconnect wires from energiser & connect volt meter clips / hang plate to energiser terminals switch energiser on to test.

To test fence line.

Faults in your fence line can be caused by shorts, vegetation growth, faulty insulation or break in the line.
To track what is happening along your fence, connect the volt meters earth clip to the earth ( dead ) wire, or to the ground ( soil ) – then place the steel hang bracket at the top rear of the volt meter case, to the live ( hot ) wire – the  volt meter will automatically turn on and display the fence voltage at your location. Proceed up and down the fence to find your fault.
