Electric Fencing

[RedViking]

An electric fence experiences voltage drop due to a short somewhere along the perimeter. The installer loops the send and return terminals in order to get the volts back up. Now my brain is telling me that he is effectively bypassing the entire fence, while the energiser appears to be functioning correctly. He insists that the fence is working correctly. Am I wrong?

What happens when you touch the fence with a voltage meter.

Sounds like it is in parallel now instead of series? Then yeah, the entire perimeter alarm function (primary function of the fence) is gone and it can be easily cut without siren going off.

Our estate's fence was breached awhile ago without the alarm being triggered. Then found out it won't get triggered if the ground isn't shorted as well. Had to fit DUT's which addresses that problem.
