    What do you get when you measure the resistance across the lead ends that connect to the 6HC?

    Nothing. It seems to be a poor connection/crimp. Not the first time during this build. I'll try redoing it. It was very hard, since I had to use thick cables for tiny crimps.

    The connectors used for those outputs accept fairly large wires easily.

    What size wire are you using?

    What sort of crimp tool are you using?

      @fcwilt You're right, the output side is fine, but the input on the smart effector is terrble.

          @velvia Tested the wires again, red to red and black to black, no problems. They are both whole.

            You mean to say they did not use the same connectors for both the input and output connections?

            That is not a good idea at all.

            You can always "cheat" a little. Short lengths of small gauge wires are not going to be a problem.

            So if you have the tools you could solder and heat-shrink two 50mm lengths (or so) of small gauge wire to the long large gauge wires coming from the 6HC. That would make crimping the small connectors much easier.

              You need to verify the resistance across the ends of the two wires that would connect to the 6HC.

                @fcwilt Did that now and discovered the issue. Yet another poor crimp by me. It threw me off since it worked the first time I tested it. Now the heater works
