???? What is a Relay? What parts does it have? What is it for? What does it mean when a relay has 3, 4, 5 or more pins? How to read an electrical diagram of a circuit with a relay? What faults can a relay in your car cause? ???? In this fifth chapter of the Automotive Electricity Course we will focus on learning and practicing with relays and electrical circuits that are no longer so simple. Therefore, if you have any questions, I encourage you to watch the previous videos and leave your questions in the comments ????
