    You are the man, thank you for this. I hate people who say don't touch anything electronic, just replace it. This is a much better answer in my opinion-- teaching and sharing what is safe and reasonable to do.

      I’m a year late but agree 💯%
      Personally I like to tinker and if I can fix it it’s a bonus can’t make it worse as it was already broken lol’
      Also helps one learn how everything works on a board’
      The sad truth with “modern day”electronics is companies either build them to fail
      (planed obsolescence) or they manufacture them so cheap
      Aka they make them not meant to be serviced’ so fixing them is near impossible’ or a new product is more “cost affective” if u can fix a tv board absolutely worth it! For a person who doesn’t know how not worth it as a new TV will cost about what a tech will charge to fix it’
      For me I agree with u all the way’
      I would repair an older electronic any day if the week over goi g for modern day cheap crap’ same with appliances 80s appliance are an eye sore but they were built like a tank! 😂
      Take care brother!

    This was extremely helpful. thank you! I had received a board from a glass top stove that supposedly didn't work. fortunately all the components on the board tested out perfect. But unfortunately these people had German roaches and all the roach crap was fouling the whole system up. I clean all the feces off of the board and it worked perfectly. So people if you have a roach problem and your appliances don't work, that might be the problem. Because roach crap really does screw the whole system up. LOL

    Quick q i have the fluke 117 there is no "rel" button on this meter to zero out the leads. Is it possible to zero the leads ? As when i set the meter to ohms and check the leads i get a reading of o.2 ohms and can't reset it to zero.

    Analog multimeters are better for this purpose, even if they are inaccurate, and old. Better response and you can test, how the device behaves. Analog multimeters are also ideal to revive locked devices or components. I could restart the charging of a locked ZTE phone, by tapping the port and batt connections with a multimeter, and it started charging. Digital multimeters are better for everything else.

    I have a electric shaver that doesnt charge anymore , i dont think its bcuz the battery is dead, i think its a technical issue that send the power directly to the motor instead of the battery
    And when its pluged into outlet, the motor starts but gradually it gets more intense, so much that i think it might damage the motor and i get it out of the outlet
    Any help? Do u have a video about it ? Or can u tell me what should i search to find the solution ?

    It just feels a bit too vague and rushed for a "Basic" tutorial; ie. You take a reading and say "Looks good!" but you never explain what a bad reading would look like or why the readings you took are in fact good.

    • @MrDmadness
      @MrDmadness Год назад +5

      It's a hair above basic. The reason the readings were good is due to continuity or lack of. And also because the resistances were within the expected ranges. It's VERY important when dealing with electrical components to expect a reading, in the case of the resistors you can consult a chart online for the colour stripes and compare to your readings.. in general if a reading is within 10% of what's expected the component is considered good. :)

      @@MrDmadness thanks for your response. My problem is not measuring components, but correct measuring in circuit. What can we expect to correctly test in circuit with accuracy and what needs to be removed for accuracy. As you and I both know, the majority of faults is with shorted or leakey caps. How can these be measured inline with accuracy?

    • @MrDmadness
      @MrDmadness Год назад +3

      @@jefffoster3557 an oscilloscope will tell you anything you need to know. With a volt meter you can test capacitors with the cap funcation ( sometimes paired with the diode function ) to co pare their readings with their identifying markers. For voltage on a board you need 2 points of contact ( one could be ground ) and touch a line trace anywhere understanding that the meter is giving you the differential between those points( eg. If you check the same live wire it will read 0volts as there no differential ) to read amperage in a live circuit is harder, there is a meter specifically for this that's expensive and who's name escapes me at present though as mentioned an oscilloscope can do all functions. One of the first things I learned doing controls wiring is that you should never take a reading without first having an expectation of what it SHOULD be. For resistance readings ( never take these on a live circuit ) it's as simple at touching 2 points and reading the reading, having a wiring diagram helps to see if you are reading g resistance through a component like a mossfet or otherwise.
      The basic triangle for figuring electrical readings out ( if you have 2 ) is this
      Volts over amps x ohms ,
      E.g..
      120 vac
      15 amp breaker
      == 8 ohms resistance .. this means that if you have greater than 8 ohms resistance your circuit will not function at all as electrons cannot overcome the resistance
      Remember also this ( compare ele tricity to water )
      Amps = flow ( same as gpm or any other flow in water )
      Volts = electrical pressure ( psi in air or water )
      Ohms = resistance ( same as friction allowances In plumbing )
      Electricians have switches and breakers
      Plumbers have valves and main isolation
      They are basically the exact same thing, except specific to their conveyed medium .
