Bro hello, one strong recommendation. You keep refering about the isolation Diodes. The job you mention and actually draw, is done by the Relays. The diode is there to protect the whole circuit when the relay deactivates. When a relay deactivates produces current fluctuations that are harmfull for circuits.
I am not an electrical engineer, I am a certified flight instructor and the purpose of this video is to help student pilots and new pilots to the Diamond DA20 understand the application and failures of the system itself. Frankly, from a pilot's perspective I don't think that it's important to be able to distinguish a relay from a diode. However, I appreciate your feedback and explanation for individuals that want more thorough understanding of electrical systems.
@@cmcintyre3165 I am not an electrical engineer either. I am required to make a brief explanation of the DA20 electrical systems for my Flight instructors Certification too, and I stumbled upon your video. If u need I can provide you with my presentation. Based on both the FM and the maintenance manual.
