Learning to Read A Wiring Diagram

This is the first in a series of videos in which I'll try to get the point across on how I read a diagram and use it in electrical troubleshooting. I chose to start out with a high voltage application because this particular electric heat kit will lend itself fairly easy to understanding. It will also allow me to go into a couple of key "rules" that I have in my head.

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.

Hopefully I can get the basics across to you on how I go about doing this when I work on a unit.
