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.
How was it like? Multiple leds which turned on depending on the voltage e.g. 1 led =2kV, 2 led = 4kV and so on?
Yes, multiple leds with more V = more LEDs
