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??

@Wolfensptz 3 года назад

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.

@harrychrusch8318 Год назад

@joejoeaz47 2 месяца назад

@Paul-ns8fr Месяц назад

When you test 30 and 87 for resistance should you have power to 85 and 86 or just test the resistance to 30 and 87?

@1magnit 4 года назад

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

@roblox-kazz-wcue4348 4 года назад

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 4 года назад

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.

@katywalker8322 2 года назад

Some relays have a diode in parallel with the coil, hence the direction of connection on these will be important. There are also some relays where pins 30 and 86 are reversed. If you mix up these 2 types (they plug into the same housing) then you land up with some odd effects!

@petewhittle2930 2 года назад

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?

@eyesofagemini7715 Год назад

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.

@Heat7215 3 года назад

Just found your site, great video, auto electric systems and tests have always been a mystery to me, this helps. More videos showing electrical auto motive test would be great (perhaps they already exist) One simple question on my part, why are there relays and what is there actual purpose in the electrical circuit?

@michaeldockins5608 3 года назад

On a circuit that has a high amperage draw there is a heat problem wherever there is resistance. Invariably that is at a switch point. so a toggle switch or other kind of switch can't handle a continuous high amperage going through it. It will burn up. So we use a toggle switch with a low amperage circuit to trigger the relay which completes the high amperage circuit to get the job done. It is really just a much heavier and stronger switch.
