Thanks for that! There is a lot of stuff to do where Heaters are concerned. I have the 12 volt motor using the Stock switch figured out and have instruction there how to use a reducer, but there is more to do. I have a DC Motor controller on order that will be a solid state solution that we can use on not just the stock switch, but any of them. More bench tests to come...
Meanwhile.. I am not ready to debut that document in its entirety yet because it isn't finished, so that's why I use an HTML trick to get just the part I want people to see front and center. If you ever see a number sign in an HTML document, it's to send the user to the portion of the document they want you to see [<a id=heatersystem>]. The rest is all there if you scroll up, but it allows you to highlight portions of a bigger article.
Two more Ranco Valves to go!
