How to Wire and Test a Relay

Today I did a mock up of a typical relay circuit in a vehicle. In this video I go in-depth of how to wire up a relay and diagnose any problems in the circuit. I explain the purpose of the relay and how it works.
How to diagnose a relay problem starts at 6:35

This video and the previous one made it easier to understand wiring better xD Diagrams are easy but with all the maze of wires it's kind of scary, great job señor.

Brother!! Thank you for making these videos. This helps me out so much on how to troubleshoot these things. I have always hated auto electric stuff. But now that I’m starting to understand it more, the more I want to learn how to deal with it. Any car I’ve ever built, I always sub out the wiring. My goal is to be able to tack this myself. I know it will take some time, but I will get it. Thanks again.

I gonna have to watch this a few times, but to no fault of yours. That was an excellent video!
I've always been completely mystified by wiring and I've finally made the commitment to master this black art. How did you learn? Clearly you have a very solid comprehension.

[@mrharlemike28]

You're the man! Phenomenal detail! 🤩

It's confusing, there's just one battery in the car. explain

[@NutsandBoltsAuto]

4:29 I used two different batteries to clearly explain that the relay operates with two different circuits. You can make the "9V" circuit work in many ways depending on your specific needs.

@@NutsandBoltsAuto okay👍

Still pretty confused
