      my small ohmmeter is a cheap old analog type...10ohm and 1k selector...

      resistance was 8~9 ohms if this is ok.

      I'm leaning towards to replace the fuse.

        datasheet for the replacement part suggest 0.6 to 2.5 ohm, but early boards could use a different part.

        do you get a 0 reading if you touch the probes together?

          touch

          let me check...

          do you want me to measure the resistance on the thermistor connection?

          by the way, this is the temp reading i have.Capture.PNG

            no, just measure the resistance from the red probe straight to the black probe, to check if the meter will give you a reading of 0 when the resistance should be 0.

                I'd expect a larger value for it to be the cause, on the other hand if it worked with the workaround (lightbulb or resistance?) then the fuse is what remains - if you have the spare then just replace it.

                (OR solder the new on top of the old, should be less risk of damage to the board)

                    this bellfuse is definitely bigger than the one that was installed.

                      assuming you guys care...

                      definitely the fuse was faulty... it measured around 13ohms when measured off the board... but the part was really tiny... who knows.

                      the belfuse was dead zero... I placed it on the back as shown on the dozuki link provided... still pending the 10kohm resistor...

                      anyways, this is my temp reading graph now.

                        interesting, which revision of the board was it you had, look at the silk screen, on the top of the board.

                        good job on getting it sorted in the end!
