      I purchased a Toyota IQ 2009 push start button last year it was good and all ( its a used car) but i didnt drive it for a little while and now that i'm ready to drive it, its not starting..... Couldnt be the battery because i purchased a new one when i got the car, i just replaced the gas pump and there's petrol in it....... When i push the button to start it stuff shows up on the dashboard but when i try to start the car its making a clicking sound repeatedly then its like its dead again. What could be the issue??

    You should always test the 30- 87 or 87a connection for Resistance. You can measure voltage or use a test light and that connection might look okay but still have burned or corroded contacts which will give you a Voltage drop/higher than normal Resistance which could prevent enough current from flowing to the Load. Your Resistance measurement should show NO resistance. There should be NO Voltage drop across those contacts. Otherwise you did a very good job producing this Video on this subject.

    Thank you so much I have plenty in my garage but didn’t understand how they work. Now that I know they will surely come in handy for many projects

    Really good video. I have very limited electrical experience but I feel confident that I could test any suspected faulty relays safely while getting tuition from this video.
    Great work @homiehektor 👏 👏👏👍

    One of the most common faults with relays is burnt contacts. Resistance checks don't work . A voltage test across the contacts under load is the test to use

      1magnit I have a silly question. How can you put a “load” on a relay that doesn’t work? If the contacts are bad or weak won’t they drop out because of the initial inrush or load? Just a couple of honest questions.

    • @1magnit
      @1magnit 4 роки тому

      A relay has 2 main parts, the coil and the contacts. You need to be more specific on what doesn't work? A open circuit coil? or contacts that don't "make" A coil doesn't have an inrush current. The load that's switched by the contacts might or might nor, depends on the type of load.

    Great video. I am a complete novice so pardon my ignorance but what power source did you use to test the relays? Can you use a car battery or?

      This is late but may help someone else reading. Use a 12volt DC direct current as ure source & you should be good. Jump start pack or a supply unit that allows for power to be switched from 69,12,24 to give adequate voltage.
