These lessons cover essential electrical and electronics lessons for automotive, truck and heavy equipment technicians in a way that minimizes excessive emphasis on electrical theory and focuses on the more practical aspects of troubleshooting vehicle electrical and electronic systems. This is a complete 60 lesson vehicle electrical-electronics training program with a review test after every 4th lesson. The lessons begin with essential electrical training and then through vehicle on-board computer circuit operation and circuit troubleshooting.
