Electrical Print Reading

Overview

This course was designed to provide training for electricians, mechanics, and others, wanting to know more about electrical print reading. The eight lessons in this course present general information about electrical schematics and electrical diagrams showing and explaining how to read and interpret the symbols on electrical schematics and electrical diagrams.
