    Ceramic Capacitors

    Hi all. I have pictured a couple of ceramic capacitors. I know the one on the left is a "monolithic" ceramic capacitor, and the one on the right is simply a "ceramic" capacitor. They both hold the same value. My question is, are they interchangeable in a circuit? The ceramic capacitor was...

    Component Identification and Information

    Hi all. I am working on another old Delco Car Stereo Control Data Module (CDM). Model Number 16169996. AM/FM Stereo "brains" part of a three component system. No schematic is available. This one has two components I am trying to identify. This should be easy for the radio guys. They...

    Component Identification

    Hi all. Can someone tell me what the two yellow components are on this board please? I see they may be polarized, due to the stripe on one end, and that is what has me confused about them. They have 106, 6K, and 210 on them. Thanks in advance for your help.

    Carbon Composition Resistor or Inductor?

    Hi all. This part has me confused. The color code (Brown, Black, Red, Silver) for it to be a resistor, would make it a 1K Ohm value with a 10% tolerance. Testing it with a multimeter set on Ohms, it comes out to 8.3 ohms, which would obviously be quite low for the value, if it is a resistor...

    Wall Charger 120VAC to 5VDC

    Hi all. My current project involves a relatively simple wall charger/power supply. The circuit board is not complicated at all. So far, I have tested each component on the board and all seem to be working properly. The only component I cannot test, with relative certainty of its proper...

    Triac Question

    Hi all. I have sourced a particular Triac (BTA800-600C) from two different places. When I put each of them separately into a Component Tester, I am getting two different readings. The components have the same component number markings on them and they both appear to be manufactured by the same...

    Inductor Question

    Hi all. I'm working on a US Model 220vac Hot Tub Water Pump that runs 24/7. They last a couple of years and then they just die. I decided to open one up and see what was inside it. According to the information I have read about this thing so far, there are no moving parts, except a...

    Hunter Ceiling Fan Receiver

    Hi all. I have tried long enough, and now am reaching out to the experts. I have a Hunter Ceiling Fan with a remote control that controls the fan speeds (3) and the lights. The lights are incandescent and dimmable, 60 watt candelabra style bulbs. There are two of them in the fixture...

    Comparable Component

    Hi again, all. I am trying to source a component I am having a hard time finding the exact numbers/letters on the available replacements. I think I may have found what I believe is the closest one. Can someone take a look at the information I have provided and let me know if I'm close please...

    Can You Identify This?

    Hi all, can anyone tell me what this is? I've looked for something similar, and plugged the numbers in a search, without luck. There are two of them right next to a multi voltage output voltage regulating component on an auto radio PCB. The numbering and markings you can see are the only...

    Delco Radio CDM Troubleshooting and Component Identification

    Hi all. I have an original equipment Delco AM/FM Stereo Radio from a 1994 Chevrolet Full Size Blazer (I bought it new) that has recently started to give me intermittent problems. About a month ago, the issues were sporadic and tolerable and would solve themselves with a power off and back on...

    Question About Resistors

    Hi all. I have a question about the placement of resistors in a circuit. In this application, the circuit involves LED's in an automotive turn signal. Newer vehicles, originally built with incandescent bulbs, flash normally with the original bulbs. When replacing the bulb with an LED bulb...

    Capacitor Substitution

    Hi all. I have tried to find a definitive answer to my question on my own, however, I am not confident in what I have found. This was my last, but obviously, most trusted attempt. I realize substituting capacitors with higher voltage and temperature ratings is acceptable, if you cannot find...

    Component Identification

    Hello again everyone. I am trying to identify a component on a circuit board. I do not have and cannot find the schematic to assist, but if you can give me a reasonable probability by looking at the component, that would help. They are small. 2.7mmx1.3mm. They have three legs and are on a...

    Resistor Value

    OK guys. This is embarrassing, but I cannot identify the value of this resistor from the color bands. Know that before coming here (as a last resort because this should have been simple), I have tried the color charts and the internet and the phone apps, but I just can't find this one. It...

    Switched Mode Power Supply/Switching Power Supply (SMPS)

    Hi all. I have a question about a power supply. Input is 120vac. There are two outputs. One is a four wire 12vdc (two pos, two neg, hooked to a single pos and single neg output on the board) and the other is 52vdc (one pos and one neg). This thing runs a surveillance system (cameras and a...

    WiFi Antenna Composition

    Hi all. Before I start taking this thing apart, because I am getting intermittent WiFi transmission and reception from it, can anyone tell me what I should expect to find when I remove that heat shrink from the antenna? Is there anything else inside there, other than what feels like a...

    Resistor Question

    Are there any other considerations I need to follow when choosing a .56 Ohm (560 mOhm) 2W wirewound resistor replacement for one that is open? There are no color bands on the resistor. It does have .56 Ohm, 481, and 2WJ imprinted on it. I am guessing the 2WJ is the wattage and the .56 Ohm is...

    Testing Procedure For this Component

    Hi all. I have removed for testing a TS2576, a step down voltage switching regulator. It was on a 12vdc to 12/8/6vdc power supply board. The power supply is to an RV Stereo/CD/DVD system for which I cannot find a schematic diagram (Quest QX3202DVD). The pins, from left to right, are supposed...

    A Diode Question

    Hello all. I have a question concerning a diode on a 12vdc to 12/8/5vdc power supply for an RV Stereo/CD/DVD Player (Quest QX3202DVD). One of the diodes (red arrow) on the PCB has a 12 volt dc charge on both sides of the diode (anode and cathode) when tested from one of the legs to ground...
