It's based around an Arduino microcontroller, some "solid state relay" chips and software to drive it. It picks temperature info and engine on/off from the Stewart Warner sender. I was going to make it work with the factory sensor but I didn't feel like solving the make/break regulation problem (long time scale filtering in software, or hardware). I built it into the old generator regulator box. It's hard to believe no one makes such a thing for sale. It's only got three wires -- battery, fan, sensor. One knob for set point. I'll post the schematic and code later. My motor controller is a bit embarrassing but I had the chips (VN05's) already so I used those. They run hotter than I like. -------------- next part -------------- An HTML attachment was scrubbed...
