Some of the most common causes of electrical problems are batteries, grounds, alternators, and starters. This self-paced course will give you an overview of batteries, how they lose power, and how to charge or replace them. Building on that knowledge, you’ll learn about the components of both the starting and charging systems, how they work together, and how to diagnose and repair common issues with them. This class teaches these concepts with text, images, diagrams, animations, and quizzes. After you finish all the labs and quizzes and score a 70% or higher on your first try, you’ll receive a certificate of completion.
