Learning to Read A Wiring Diagram Part 2

This is the 2nd of videos that I am putting out to try and help people understand how to read a wiring diagram and use it in electrical troubleshooting. I am moving from the electric heat kit I started with in the first video and into the air handler that I have in the shop. I continue with the couple of key "rules" that I have learned over the years and attempt to help get this across to whomever watches this video. Remember that what I go over here and how we look at things will have to apply to anything we connect to this component. Even though you may have a residential, or commercial system, that has some add-on electrical parts not associated with the original air handler or outdoor unit...that doesn't matter...all of it has to fit together to be one functioning system. 00:00 Intro 01:20 Rule 2 01:50 Look at the air handler 03:48 Air Handler Wiring Diagram 04:53 Primary Side of the Transformer 06:52 Rule 3 08:00 The PSC Blower 10:05 Low Voltage Circuits 11:00 24v Red Wire/Fuse/Thermostat Circuit 12:35 Blue or 24v Common Circuit 13:27 Green or "G" Circuit 13:41 White or "W" Circuit 14:43 Brown or "W2" Circuit 15:30 High Voltage Purple Wire 16:27 Outro
