I lost my electric fence tester, probably the pigs ate it. But I opened it once to resolder the earth wire and found it’s really just a voltage divider with resistors and leds, so I can probably rebuild with stuff I have. What resistor values though? 2k to 10k V run through the fence. If any of you good people have a diagram, a formula or an idea, please help.

    You could use something like this:

    The diodes at least provide some steps - which just LEDs and resistors don’t. The dissipation in the main series resistors will be quite something, also. (You will probably need several resistors in series, if you use standard ones, with their standard voltage limits).
