Problem Solving Tips

Problem Solving & Tips

It is essential to check the power on your fence regularly (see “Fence Testers”) as this can alert you to a problem which is or might be slowly occurring, such as vegetation reducing the power on your fence line. You need a reading of over 2,500volts for most animals.
It also helps identify the problem area.

Fault Finding

To help identify where the problem is – first check the energiser by disconnecting the wire joining the power from it, to the fence line. Then carry out the following checks:

Mains Energiser checks:

• Is the energiser in a dry weatherproof area?
• Is the energiser turned on?
• Is the energiser emitting an audible tick?
• Is there a light flashing on the unit?
• Do you have cable specially designed for taking the power from the energiser to the fence line, normally referred to as a “Lead Out Cable”.
• Disconnect the wires to the fence and earth system, connect a fence tester directly to the two terminals where the wires were connected, is there a power reading?
If the answer is yes to all questions your energiser is working.
If the answer to any question is no call us for advice.

Battery Energiser Checks :

• Is the energiser turned on?
• Is the energiser emitting an audible tick?
• Is there a light flashing on the unit?
• Having disconnected the power wire to the fence also disconnect the earth wire, when you connect a fence tester to the two wires, is there power at the end of the wire?
If the answer is yes to all questions your energiser is working.
If the answer to any question is no call us for advice.

Fence Line Check

• Mains Energiser- Having checked the energiser operation (and reconnected the power and earth wire if they were removed from the energiser) then disconnect the wire carrying power at the point it connects to the fence line. Connect the fence tester to the end of this wire. Is there power at this point?
• Battery Energiser – disconnect the wires that connect the power to the fence and the wire which connects the earth wire to the earth stake. Connect the fence tester directly to these wires. Is there power between the two wires?
If the answer is yes to all questions your power is getting to the fence line and the problem is in the fence or at the earth stake.
If the answer to any question is no check the wires for bad connections and breaks and any damage.

• Is the fence line clear of vegetation?
• Are the insulators in good condition?
• Is the fence line fixed correctly in the insulators?
• Is anything touching the fence line?
• Are the connections clean and with no rust?
• Are correct joiners used?
• Is the fence line length of the fence matched with the energiser output?
• Is the fence line in good condition with no breaks?
If the answer is yes to all questions the problem is with the earth system.
TOP TIP – if you can hear a clicking on the fence line this indicates where there is a problem (not that the fence is working, as many people think).

Earth System Check

Approximately 100 metres away from where the energiser is connected to the fence, use a metal bar to short out the fence to the ground (just lean it on the fence while it remains in contact with the ground) Use a voltage tester, preferably a digital type, to check if you have power on the earth stake (push the tester probe in the ground and touch the stake with the other connection on the tester). If you have a reading over 400 volts then you need to increase the earthing system using more stakes, or longer ones. An earth system relies on using the moisture in the ground to assist its operation. Dry conditions, rock, sandy gravel and chalk soils can all reduce the moisture, making it essential to use longer or more stakes. The stakes need to be spaced at recommended intervals (this depends how long the stakes are) and they need to be linked together to increase the ground contact area.

Radio Interference

All the energisers we sell meet legal requirements relating to radio interference.
Interference is usually caused by poor connections and problems with the electric fence which are resulting in the electric arcing (shorting).
TOP TIP – pay particular attention to any joins and connections and this will reduce the risk of any problem occurring.

General Information and Advice

Electric fence lines should not be installed parallel to, and directly below high voltage cables. It is generally acceptable to cross under them as near to a right angle as possible.

Electric fencing can be installed next to, and along footpaths crossing fields, but you must display an approved warning sign every 50 metres.
