| Symptom | Common causes |
|---|---|
| Low fence voltage | Vegetation, cracked insulators, poor earthing, undersized energiser |
| Fence constantly alarming | Broken wire, short, faulty gate contact, zone set too sensitive |
| Fence will not arm | Open circuit, zone fault, keypad or remote fault, low battery |

| Fence dead | No mains, flat battery, blown fuse, energiser failure |
| Faults after a storm | Broken wires, lightning damage to insulators or energiser |
How Technicians Trace Faults
- Check the energiser. Power, battery, fuses and error logs.
- Isolate the line. Disconnect the fence to see if the energiser recovers.
- Test by zone. Voltage readings on each zone to narrow the area.
- Walk the fence with a fault finder. Current direction shows where leakage is.
- Listen and look. Clicking, arcing marks and burn tracks on insulators.
- Test the earth. Earth spikes and connections checked.
- Fix and retest. Repair the cause and confirm voltage on every zone.
Note when alarms happen: rain, wind, night or all the time.

Checks You Can Do Safely
- Confirm the energiser has power and look at the display or lights.
- Walk the fence with it switched off and look for obvious damage.
- Check for vegetation touching the wires.
- Note any clicking sounds and where they come from.
Do not touch the wires while the fence is live.
Common Cape Town Causes
- Wet winters. Rain and wet leaves are the classic night-time alarm trigger.
- South-easter. Wind moves loose wires onto brackets, causing intermittent shorts.
- Sandy ground. Dry sand in the Northern Suburbs, Table View and Melkbosstrand can weaken earthing.
- Salt tracking. Salt deposits on insulators near the sea leak voltage.

Electric Fence Fault Finding Questions
Why is my electric fence voltage low?
Most often vegetation, cracked insulators or poor earthing. An undersized or failing energiser is the next suspect.
Why does my fence keep alarming?
Usually a broken wire, short or faulty gate contact. Intermittent alarms in rain point to leakage.
Why will my fence not arm?
The energiser sees a fault on a zone, or the keypad, remote or battery has a problem.
Is clicking on the fence normal?
A regular tick from the energiser is normal. Clicking or sparking at a point on the line usually means arcing.
Can a technician find an intermittent fault?
Usually, but it can take longer. Energiser logs and your notes on when it happens help.
