PROBLEM

PROBABLE CAUSES

Energizer not on or no voltmeter reading across energizer output terminals when disconnected from fence.

·  Mainline power outage
·  Blown fuse on input circuit
·  Energizer switched off
·  Dry cell batteries dead, wet cell batteries discharged
·  Terminals corroded
·  Faulty energizer

Energizer on but low voltmeter reading across energizer output terminals when disconnected from fence. 
(classic signs of bad transformer)

·  Energizer switched to low setting
·  Weak batteries
·  Terminals corroded

Energizer connected & operating but no voltmeter reading on fence.

 (Dead short on fence)

·  Ground-return wire disconnected or broken
·  Feedwire terminals corroded, disconnected or broken
·  Broken live or ground-return wire on fence

Low voltmeter readings at several places on fence.

·  Energizer on low setting
·  Energizer inadequate for length of fence
·  Weak batteries
·  Terminals corroded
·  Ground system inadequate
·  Soil dried out

No voltmeter reading or low reading at one location on fence.

·  Broken wire
·  Dead short across wires
·  Broken or disconnected jumper wire
·  Disconnected or deteriorated ground rod

Voltmeter reading on one wire higher than another or no reading from one live wire to ground-return wire or soil.

·  Broken or disconnected fence wire
·  Broken or disconnected jumper wire
·  Broken or disconnected ground wire
·  Broken or faulty insulator
·  Ground rod deteriorated

Radio, TV or telephone interference.

 (major short on fence)

·  Ground system inadequate
·  Antenna too close to fence
·  Fence parallel with antenna wires or telephone wires
