Daryl...what is the wattage of the fixed resistor you use for speed control? Thank you.My thaughts on this are that the beter way is speed controlled by the temperature as in the Waeco system. Where if the temperature rises too high the processor then gives a higher compressor speed. then reduces it when the temperature is nearer where it should be. That being said im not into processor design. My approach in portable 12V DC refrigeration is simple is best. I do have 2 Waeco fridges, but I also converted a Evakool fiberglass esky which has far beter insulation than the Waecos. I just used a $15 electronic thermostat from Ebay. My compressor speed has a switch for economy 2000rpm & power 3000rpm. It spends most of its time on the economy seting, The power setting is only used if ive loaded the fridge up & want it cooled quickly, then it lives on economy. This is my converted Esky.View attachment 97515 View attachment 97516 View attachment 97517 View attachment 97518
