How Relays Work, Why They're Used, & How They Fail (Disassembled Relay Explained)

[@Coastal0]

Would love to see a simple explanation for solid state relays, now that you've mentioned it!

[@CarsSimplified]

I'll have to do some more research on those, but I already have a solid state flasher relay ready to film, so I'll put it on the to-do list!

[@davebwilliams]

Super helpful. Thank you.

[@robertferraiuolo3675]

Great explanation. Thanks!!!

[@SalemDoyle]

great video. Also, thanks to relays, it's possible for a single switch to simultaneously turn off and on multiple circuits. oh the joys of technology.

[@CarsSimplified]

Thanks! It is indeed! I also forgot about the fact that on board computers can control or override components, too.

[@rawr7502]

Great video thank you!

[@tonyswagz]

Great video, does relays need to have specific numbers like fuses to be replaced or can any relay work as long as the pins are the same?

[@revmatchtv]

Great explainer!

[@CarsSimplified]

Thanks!

Hi. Thanks for the clear information. I did subscribe. Before I watched your video I watched one where the guy slopped the dielectric grease all over the metal contacts on a trailer connection he was installing; both the male and female sides. Is he just totally misinformed?

My car horns are perfect ground is good wiring everything is good but it sounds weak sometimes .. can this because of a bad relay

[@CarsSimplified]

If carbon builds up on those contacts, it can add resistance which can alter the pitch and/or volume of the horn. On a dual horn system (the harmonic horn tone many cars have) a loose connector/wire near one of the horns could make one work intermittently. A relay seems like the more likely issue, and really easy to test if there is an identical relay that can be swapped out that isn't vital to the car/safety while testing.

My parents named my oldest brother load number one.

Amazing Explanation! Thank you

[@CarsSimplified]

Thanks!

[@silvervortex2441]

​@@CarsSimplified looking forward for more automotive electronic explanations ;)

[@CarsSimplified]

They won't be every week's topic but I will definitely keep making them fairly often!

[@kw0060]

thanks for the straight to the point video loaded with information!

[@CarsSimplified]

Thank you for watching! That's my favorite kind of video to make!

[@davemcguigan218]

Fascinating stuff, great explanation!

[@CarsSimplified]

Thanks!

[@gaiagaiagaiagaiagaia]

Wow these videos are amazing. Thank you so much!

[@stevenwarrener8533]

Dude I love this guy! Thank you so much I have learned a lot already from your videos. I appreciate you doing them!
