    Part that looks like a resistor with only code CEC

    There may be more than the 'CEC' marking, on the other side of the devices that will supply more information on the component's identity. Barring that, is the 'broken connection' just a detachment? Can you resolder the connection using a soldering iron (are you familiar with their use?) Good...

    Is there a liquid conductor out there, or that I can make?

    Sounds like you're gone, but in keeping with the topic of this post I thought I'd give an answer to anyone else who looks-up this information. GC Electronics has made a brush-on conductive coating for many years. It may not work in the application of this post, it's designed primarily to repair...

    P1203ED equivalent

    I know it doesn't help, but I couldn't find a substitute for that part number. If it helps, I did see a reference that a Chinese company called NIKOS (Niko Semiconductor) also makes it. You're probably stuck with trying to track down an exact part number replacement.

    How to read a 5-band resistor that has its bands spread evenly?

    I see a lot of them, *steve*. They're coming from no-name (alright, fly-by-night) Chinese manufacturers who I can't find information from (in English anyway). Some of them actually omit the tolerance band. Others use two bands for the multiplier (adding a black band to substitute for one of...

    Trouble with assembling electrolytic capacitators

    If some of them do what you want them to, and some don't, I would assume there is something about your construction technique that is prone to variation. I'd pay special attention when I assembled each one, and try to determine where the variance is occurring.

    Toggle switch without the switch?

    It SOUNDS like you mean a 'Momentary' contact Push Button. Depress the push-button to close the circuit, and release the push-button to open the circuit contacts. Is that what you meant?

    Yamaha EMX amp blows main fuse

    Maybe, one of the Voltage Regulators itself is defective. Just because they're new, doesn't mean one doesn't have a defect. Otherwise, I'd go with electrically isolating them from the chassis. Mica washes with heat sink grease. Harald is right, that a positive and negative voltage regulator...

    How to read a 5-band resistor that has its bands spread evenly?

    You can Google the resistor color code system, and find what you need. Different sites show a variety of charts. I agree, some of the resistors I've seen with the five bands, are difficult to decipher sometimes.

    microwave oven motor makes noise after couple hour of use

    I would suspect as BobK mentioned, that the laminations in the motor may be overheating, warping them, and causing the scraping sound.

    Trouble with assembling electrolytic capacitators

    Is there someting in the chemical composition of the duct tape glue that may be causing unexpected problems?

    24 volt ac relay chatter in parallel to doorbell

    duke37 is right that a single diode across an AC relay coil is not correct. A single diode is often used with a DC relay coil. What is normally used for suppression of voltage spikes on an AC relay coil is called a 'snubber' which is basically a resistor in series with a small capacitor across...

    I have no idea

    We can probably help, but we just don't have enough information to tell you much right now. Is this a home-built device, or can you give us a commercial model number of the device with maybe pictures of what you have, and a more complete explaination of what you need to do. I know what you wrote...

    24 volt ac relay chatter in parallel to doorbell

    I'm trying to visualize that. Are you somehow accidentally short-circuit wiring something there? Are you sure that what needs to be wired in parallel or in series, is wired that way? It sure sounds like your LED doorbell might be causing the problem. I'm just wondering if you can eliminate...

    Does Your Wiring-Soldering Look Like This?

    As advertised: A 'simple' VFO. It probably doesn't get much 'simpler', than that.

    24 volt ac relay chatter in parallel to doorbell

    It's possible the doorbell LED is causing a problem with your circuit, but first things first. Are you sure you have the appropriate relay (coil) for your circuit. AC vs. DC? It should be marked on the relay itself. You're powering your relay coil from what source? A traditional transformer...

    Cartridge Heater Circuit Burnt

    Did the burned resistor burn itself 'open circuit', or can you read a value across it with an ohmeter? That might at least get you in the ball-park for a replacement. You're bound to have other damage on the board due to the excessive current through the burned resistor circuit. Do you have...

    Resistor ID on stove igniter board 9758080

    It seems obvious, but because so many manufacturers use this board, did you try to Google a schematic for this board part number? If a schematic is out there, you can eliminate a lot of guess-work.

    help for understanding SMD marking code

    Hopefully someone will recognize this marking system (I don't). In most cases, while this marking system seems more detailed than most I've seen, it helps a lot if you know who the manufacturer is. Can you determine from the manufacturer of your special device, who, may have supplied these...

    Super Long Thread Question - Motorcycle Turn Signals

    Just some input that I can think of: I don't know where you're at, or what motor vehicle laws you may have there. I would assume that there are certain laws concerning the minimum/maximum brightness, and also the visible angle your lens must have to meet road requirements. I'd check into that...
