electric fencing on indicator

Recommended Posts

What I am trying to do is to install a ultra bright LED on an electric fence, this would, at a glance, one could see if the fence is on, if possable a few of these lights arround the fence. These LED'S would be powered by the energisor, 10.000v at 8J. pulsed at 900ms.

I am assuming that there is a low power side to this circuit. The electric fence amplifier box is stepping a smaller voltage up to this level. Why not use a voltage divider on the low voltage side to bring it down to 2 V or thereabouts and run that through a resistor to the LED? It will be much less expensive for parts to step up than to step down in this case. You will have the same result, because if the low voltage that is supplying the circuit is not present, then there is no high voltage present, etc.
