In order to quickly diagnose and repair the many complex systems in today’s high-tech vehicles, the fundamentals of these systems have to be second nature to automotive repair technicians. This class will help you build up the knowledge you need to make this happen.

David Hobbs covers how an alternator works and how they provide power. He explains the components of an alternator, their functions, and why they do what they do. This class also covers types of alternator fields, what they are, and how they differ. It explains the function of a voltage regulator, how diodes work, and what causes current change. David also provides hands-on test procedures using a VAT 40, volt meter, and amp meter.

Free up your brain for more complex issues by making the basics second nature. By mastering the basics, you could be on your way to becoming a “super tech.”

• What the “voltage drop” and “alternator ripple” tests are and when to use them
• Explanation of multi-wire voltage regulator connector
• Common alternator failures and their probable causes (such as voltage spikes)
• LOTS of tips and hands-on testing
