    XBox Series Controller - Component ID

    SIR SWEEP . . . . . Neither WJ3--- nor ---1o are researching out as being viable identifier codes for Q3. So o o o o o o o o o lets just take DC metering and see what is to be found . I am more inclined for Q3 to be a common bipolar transistor. . . . . . probably NPN. Look at your provided...

    Complex unit fails to power up

    Dr Edd calling the Dick Dr . . . . come in pls . . . . . . With 2004 to 2024 having that unit plugged in, has probably left some of the units E caps in such a depleted condition, such they no longer have enough OOOMPH to start up the power supply portion of the unit after you totally lost...

    Ignition Coil Fence Charger

    Sir whfarms . . . . and have even built one. It would not not hold a mouse. I wonder if that reason might have been that you used a new generation spark coil , and not one of the pictured older generation . . . .akin to this type . . as having either a 6 or 12V primary. This " old school "...

    Whirlpool oven timer problem

    1 Form-B relay - normally closed . . . . means you need to take the non powered board and use a 6VDC power source to touch to the relays end coil terminals ( small pins) and listen for a click and ohm out to see if the power contacts opened. If so, then you need to connect the board to the...

    Whirlpool oven timer problem

    Sir MDJolley . . . . . If you pop the tabs on the pcb case (grey clear plastic)and show the other side of the pcb, there may be a different story. If you (press back)the 2 far rear tabs on the pcb case (tough LEXAN plastic) and then fight the 4 minor side tabs,you may find more discrete...

    Wall Charger 120VAC to 5VDC

    Sir H2814D . . . . . Looks like you got the unit functioning again, before I had this info available . . . . but I will post the possibilities anyway . . . . . I marked up that data sheet and circuit board, in relation to your supply's board foil paths and placed it below. POINTS OF INTEREST...

    pioneer cdj 1000mk2 coil problems

    Sir 7 heaven . . . . . You say . . . . the coils shown in the diagram are all faulty I looked them up and the pink box and their positioning on the schematic reveals them as being high frequency EMI-RFI supression filters in the 1.8 and 3.3 V power supply. This is on the IC501 in my snippet...

    Need to find where i can get a ceramic cement resistor or equivalent please. The white 2W 3ohm 3K in photo

    Sir Texascowboy . . . . . . . . ("Here We Go!" ) THINK ABOUT THIS NOW . . . . . . We see the . . .erCAP ker V1 Circuit board, which we are to assume that initially rated 2 watt wire wound resistor come from . . . . and you never did definitively say if the resistor...

    dt9205a

    Me too ! . . . . . . but only for researching its other ends " # " location on the schematic. As can be seen, it only comes into play, when switched in on the seven different ohms ranges. S o o o o o o o o o o o o o o o o . . if you had your unit on ohms function and then subjected its...

    Need to find where i can get a ceramic cement resistor or equivalent please. The white 2W 3ohm 3K in photo

    With that 3K tacked on the end , but with no intermediate R inserted . . .its a puzzler. If the unit tests as open with an ohmmeter connected to each leads. Then try this . . . Use a jumper clip or bared wire to connect both end resistor leads together and that will be 1 connection to an...

    Coffee pot component.

    Don't I reads that depicted one "shotted " thermo/fuse as being a TEAPO brand and of a 240 C . . . cen-ti-mum-uh-grated blowing up temp rating ? If so . . . . . .MAN! . . . . . . . .You'se done gots yersefs one HOT pot !

    Children's electronic motorbike upgrade

    What does the old pot read from either end to rotor ? It now could have opened up from the hi speed end . . . . . Thus no control. I would be solder tacking on 47 k resistors on each end of that pot and then re tacking on the lifted wires to have 47 k added on each end. Then test to see if all...

    Coffee pot component.

    The thermostat that was on the heating element has no continuity, so I had a different one I put in. Is there anyway to test the old one to see if it's an off then or a burned out on then off? Both thermostats should read shorted at room temperature, then bi-metallic strip activated switching...

    Help diagnosing Trinitron KV-32FV27

    I never received the DEFINITIVE answer on using OHMS function on your meter, instead of the "shotgun" interpretation that is being provided by using its continuity function. ( 1 ohm beeps . . . . . . .BUT . . . . . .500 ohms also beeps ! ) BUT . . . . . lets go back to the orderly procedure you...

    Fixed reading error in DT-9205A multimeter

    VERY weird . . . .in the choice of part number assignment of that I.C. . . . . .UNLESS . . .that was being from the units first line of marking. In my eyes mind, I would want to see that being as "shorthand" for a "HC14" . . . . . which is a schmitt trigger enhanced hex inverter.. . . . as...

    Component id needed

    No-no on varistor. Looks like a paralleled ceramic capacitor and an anywhere from 2.5-4 meg resistor (being permissible) that would be from a circuit negative ground to chassis frame position. An ohmmeter and testing with one of its leads floating . . . . should confirm that resistance value...
