I went thru this a while ago and have asked as many sources as I can find -
but no results that work.
I'm using an electric water pump. I want to use a dash mounted 12v LED
indicator light to tell me when poser is available to the pump motor but it
isnt drawing power, letting me shut down as soon as possible. I dont want to
rely on just a water temp gauge (although I have one). Does anyond make or
know of any sending unit that might tell me a 'low amp draw' condition by
closing a 12v circuit that I can wire a lamp to? Do you know of any other
passive (e.g., not a series-wired relay) device? Any diagrams?
