    I require help repairing a Kitchenaid Water Kettle

    Hi chrotesque, Have you had time to check what Adam suggested? Only now, test the input to the transformer. The Red and Black. If you get voltage to the transformer and nothing out of it, Adam has done it again.... He is always ten steps ahead of us mere mortals. Martin

    Siemens waching machine Siwamat plus 7421 repair-need schematics

    I am not sure for different countries. But UK would be BROWN = Live, BLUE = Neutral and green/yellow = Earth. But the 'loud boom' has to show some kind of failure somewhere.!! Does the motor spin by hand? Pull the belt to rotate it. Turn the drum and try and see if something has seized. If you...

    Siemens waching machine Siwamat plus 7421 repair-need schematics

    Hi dorke, I can't find a schematic for it. When you say the line lamp is on, is that connected directly to mains in (neon) or through a switch on the machine? Some items to check. Filter capacitor, normally located on the bottom somewhere. Motor. Pump. Wires for short circuit. Heating element...

    FTDI, USB-serial adapter

    Yes @Gryd3 the driver was part of a Windows update. Microsoft are not happy about it and apparently pulling it from the update. But the damage is already done for so many people. Dave Jones in the above video tackled them and they rplied. Quite a funny video. Martin

    power dissipation capability

    Hi, It's something to do with thermal resistance. And probably to do with manufacture. A good example would be a computer processor that gets so hot it needs a heatsink and fan. A calculator has a processor which can run all day without getting hot. It clearly has something to do with speed and...

    Battery charger diagram

    steve said [MOD] I'm editing this in place because it's important to realize what is definitely wrong. It would have been nice if you highlighted these points too!! I made it quite clear NOT to try it and it was a GUESS. I also stated "wait for other members input". I am not sure if getting...

    Hi steve, wouldn't that be a straight short across ac input? Martin

    continuity, insulation and isolation testing

    As pm'd to me. " Thank you for your kind reply. I assumed that's what insulation testing was. If everything is insulated ok and we apply a voltage for the connections in this test am I right in saying that the resistance will be large? Does this also apply for isolation. Circuit isolated, low...

    Battery charger diagram

    [MOD] I'm editing this in place because it's important to realize what is definitely wrong. Hi Frank, I will have a guess to get this thread started!! This is by no means HOW to connect it but a GUESS. You should really use a multimeter to check polarity and voltages. I am assuming BLACK to be...

    Need help reverse engineering a PCB

    All 8 pins are used for signals, and all or most can be switched to be used for power. The outer plug shell is used as ground reference and connected to the device shell. At least one (probably at most two) of the pins is used for detecting what sort of plug is plugged in. All plugs have to...

    Need help reverse engineering a PCB

    I can certainly see why you are having technical issues. You are probably communicating with a 5 year old who has a pocket flamethrower. Martin

    continuity, insulation and isolation testing

    Hi Stuart, Continuity is simply a circuit that is connected, current will flow from one point to another. Think of it as checking a fuse or light bulb. If that fuse is blown, there is no connection from either side of the fuse and therefore no continuity. Isolation is quite simply as the word...

    I require help repairing a Kitchenaid Water Kettle

    I personally find it fascinating. I also find you checking willy nilly . You are playing with mains voltage and very dangerous. This is not a led christmas light. You are playing with possibly 13Amps. Please don't take it in your stride.

    I require help repairing a Kitchenaid Water Kettle

    Trust me, your explanations are perfect. You should be proud, and we need more people on this forum who can explain things like you... The BIG blue and BROWN wire are more than likely the heater elements power. Put meter on V and check these CAREFULLY while switching the kettle on!!

    I require help repairing a Kitchenaid Water Kettle

    It can be quite shocking too. OK I have advice not to carry on with this BUT, be very careful. Lets first try the big blue and brown wires voltage. in the centre of the base there is blue and brown. can you check first that there is voltage? Change your meter settings. Then flick the base...

    I require help repairing a Kitchenaid Water Kettle

    Thanks again, you are superb. I do have to say that all our findings so far are preliminary. We may have to go back and do finer checks. So far your initial checks are fantastic. You only have two more components to visuably check. The capacitors. The black cylindrical items, they are called...

    HOME THEATER AUDIO CUTS OFF

    Sorry Dave, Just giving an idea for audio modes as OP. I/we call them inputs or outputs. I was just trying to help the OP to better explain him/herself. I am certainly not questioning /asking you!!!! Sorry, Had to edit this because I didn't explain myself in my post. Martin
