I am asking some questions. I recently replaced the fuse box board in my car with new resistors (122). It had nearly flawless resistance of 1200 ohms prior to my installation of the new resistors (122). However, upon installation and verification, the resistance of four resistors was reduced to 456 ohms. and 38 ohms is displayed by the other resistors😯. Then, believing that I had simply burned the resistors during installation, I took out one of the 38 ohm resistors. then the test returns with the accurate measurement of 1200 ohms. What might the problem or issue be? however, as of right now, our car is operating without an alarm. I am grateful in advance. I am hoping you will read this and respond to my queries.
I am not an electronic engineer or an electrician. I simply study on my own to get our car fixed. Because I cannot afford to pay $300-4000 for repairs or to purchase a brand-new one for about $600. I ended up saving $597. Because the resistors I purchased are only $3 for 50 pieces. 😊
If you get continuity, it indicates a short circuit, and the voltage regulator should be replaced. If there's no continuity, the second test is more thorough and involves checking the input and output voltages.
Why does the multimeter no beep but I know the bulb works. I’ve put it into the continuity setting and touched the two leads to make sure it works. So why does the multimeter not signal that the light bulb allows the flow of electricity?
Thank you. Can I please ask, if a TV power board has 2 x 450v capacitors should they read at 450v or is it just the max tolerance? Mine both read 350v would there be a problem with a component upstream or is that normal on standby? Thank you Tim
When I measure from 1st to 4th leg i don’t get 1v like you do. only 0.5v (like all other measurments minus it being blocked in reverse). Does this mean my rectifier is faulty ?
Thanks for the vid. So if i test my plug socket as you said and the neutral and ground give zero volts, does that mean that my house is properly grounded?
@@ElectroUniversity Thank you for replying. I checked the resistor according to the information you provided (thank you again). It's 105 and the resistance should be 1M ohms but the Multimeter is not giving as should be.
What about adding the voltage for the center pin vs the inside of the barrel connector? Some chargers deliver 5Vsb to run the switching circuit that turns on the higher voltage.
@@purplefurture6960 Exactly I use a test light to check the relay You must have power on +30 and 85 or 86 When the relay doing a click then you must have power on 87
Good video, but there is no way an average person without scientific equipment could accurately or even estimate how much is left in the battery. There are way too many existential factors at play. The only accurate way is the multimeter! Just saying this because people come looking for a way for sure.but this is not for sure. The princeton research was done using epoxy tables and tubing. No other factors at play. Research is inconclusive at best.
@@ElectroUniversity hi thanks for reply ...so obviously this would indicate a " faulty" bad resistor! Am i corect? Then when im getting NO beep on most resistors they ALL " good"
