Don't remember the drawing, but do remeber talking to you about your setup or relays or something. It was not long ago when only a few of us fish geeks knew what a latching circuit was. Kind of funny that several ATO companies have sprung up to sell the exact circuits that we draw up for people (not that there is anything special about a latch). The best part is that one of them copied an untested concept type schematic that I posted here on RC. They did so without asking or understanding the circuit topology and its serious flaws. They sold the unit for at least a year with the severly flawed "run dry" protection.
Anyway...
