No voltage on the other end of the relay, this with nothing but 12vdc into the board, red led on, relay clicked when powered, no sensor, no output connected. Should I have 12vdc on the backend of the relay at this point? Wouldn't I NEED 12vdc on the back end to make it trip/click? So I wonder where to start checking for "operator error"? I guess I'll get the schematic out and try to trace thru and see if I have a diode backwards or something. I have all the black bands to the white band on the board, my interpretation of how it goes.
