Self-paced Electrical Repair Course

If you want to learn truck electrical repairs, then this is the place. We have developed a completely FREE Self Paced Electrical Repair Course which you can study right here on the Internet. We will provide the required electrical theory that you need to become an effective truck electrical troubleshooter. This course will NOT bog you down with fancy dancy theory which you don't need. If this course covers theory, then you had better pay attention because it will help you resolve electrical problems later.

Increase your value to your employer, and take pride in your ability to understand and fix those electrical problems that keep other mechanics baffled.

During the spring of year 2001, this site is new, and some of the below listed course topics are still under construction. If the bold topic name is not underlined, then that topic is still under construction and will be available soon.
