Hi all - I stumbled upon this site while researching how to build an electric fence status indicator. To give you an idea of what I am attempting to do is, build a simple circuit that would be able to flash an indicator light when the fence pulse is below 750v (Red), between 750v - 1500v (Yellow) and over 1500v (Green) that can be seen at night from a distance of 1000'. I have a small farm and being able to glance out the window from the house to ensure the fence is up and running quickly would be sweet.
