Learn how to test Relays with multimeter, how relay works

[@ligma8353]

Thank you. This was a good easy to understand explanation.

[@desirelungu5137]

thanks alot sir for nice lesson, I would like to ask if you test without removing it Frome the board does it gives correct value?

[@markw3922]

question please , can these be resistance tested in situ i.e still installed onto pcb with other pcb components still present but removed from the pcb power supply ? obviously not powering them with external rated power 12v in this case while still connected is probably a bad idea but will the circuit affect the readings.

[@ivyfrazier8039]

Great demonstration. Thanks!

[@electronicsrepairbasics_erb]

Glad it was helpful!

[@tauraimachingura]

Understandable,thank you Sir

[@electronicsrepairbasics_erb]

So nice of you

[@vikramtrivedi5468]

Thank you very much Sir. If possible please make a video on Optocupler testing. 4 pin and 6 pin.

[@electronicsrepairbasics_erb]

You are very welcome. Ok I will make it today for you.

@@electronicsrepairbasics_erb sir, why dont you used DIODE in the car relay? Where is the diode? Please explain why diode is not present in the relay?

[@awaisahmed5537]

Really appreciate you sir ❤️❤️❤️

[@djdarkpsycho]

Can you apply voltage to the relay and measure continuity and resistance? Will not damage the multimeter?

[@ashrafkarjiker6888]

Can you use a bench power supply to apply voltage to the relay and is it always 12 volts

[@electronicsrepairbasics_erb]

The relays have usually the working voltage of 12VDC and 24VDC.

[@ashrafkarjiker6888]

Is it possible to test the relay in circuit on PCB board

@@electronicsrepairbasics_erb diode protect the circuit from reverse coil relay voltage. Why is diode not present? Please explain.

[@tnamen1307]

please explain why diode is not used?

[@electronicsrepairbasics_erb]

Simply the diode is not used in relays because it is not necessary

[@tnamen1307]

@@electronicsrepairbasics_erb then how does the circuit protect itself from the huge reverse spike voltage produced by the relay??
