    I am powering up the solenoid directly for the test, so bc337 is not in scope.

    I am thinking the inrush device cut off the power supply when too much current is drawn.. But I will replace it to see what happen.
    So I replaced the PTC with a similar device extracted near incoming live input from another power board. Powered up and immediately a tiny spark is seen, and nothing else happened. Restored the original PTC, does not work already..

    On quick check - the C106M appeared faulty. Pulled this out of circuit - Gate is shorted to Anode and Gate is opened to Cathode. With DMM black probe on Cathode, red probe on Anode, then "shorting" the gate with red probe, nothing happened. So I believe this SCR is already fried..

    Could this SCR been faulty in the first place ??

      I have a feeling that this might have been the case

      30 Desk Top Switching Power Supply
      10 Battery Charger Switching Power Supply for Power Tool
      6 18v Lithium Battery Power Boards for Tool Battery Packs

      1 Dell Mother Board
      15 Computer Power Supply
      1 HP Printer Supply & Control Board * lighting finished it *


      These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

      1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
      2 Hem Saw Computer Stack Board

      All of these had CAPs POOF
      All of the mosfet that are taken out by bad caps

        Happy New Year

        Latest update:
        I have replaced the C106M, and it does not have the same "click-on-click-off" sound every 5 seconds anymore. And the incandescent bulb connected in series does not light up on starting up with the load. But then again, it actually does nothing...

        Meaning, it reading 250Vdc across the 2 output pins without load, and read 0Vdc when connected the solenoid... When connected to the incandescent bulb or the DC motor, nothing happen...

        So, I ran out of idea what else to do with it, and decided to give it up... I salvaged some parts are spares, and discarded the chiller..

        Thank you Sam_sam_sam for working with me all along, have a great 20201!

            The replacement should be C106MG, available from digikey C106MGOS-ND
