Automotive Video presents a brand new training program, A/C Best Recommended Practices, on air conditioning fundamentals with Bosch Field Sales Technical Trainer Bob Pattengale. Today, virtually every car has air conditioning, and virtually every car is going to need to have that air conditioning serviced from time to time. In this 75 minute training program, Bob focuses on the best recommended practices: the steps that you need to take long before you hook up an air conditioning machine. Are the belts in good condition? Are there any leaks in the system? Is the heater valve stuck open? Do you have a dirty cabin air filter?

These videos are brought to you through the efforts of the Wells Technical Services Department. The Wells Technical Services department has developed this video series with dozens of in-depth training segments covering a broad range of drivability and related topics. The videos can be accessed by searching for “Wells Vehicle Electronics” on YouTube.com and through the company’s award-winning www.wellsVE.com website.

He also goes into detail regarding how the FRED also handles the regulatory side of things such as EPA guidelines and leak tests.

By Gary Goms. This real-world case study of a 2002 Chevy S-10 pickup, a 1995 Buick and a 1995 Lincoln Town Car illustrates why "chasing" trouble codes can get you lost in the Diagnostic Woods. Working as a part-time mobile diagnostic technician, I find that many techs find themselves “lost in the woods” while diagnosing engine management system failures. Although not perfect, the “lost in the woods” analogy describes the dilemma of a technician through a forest of information without a good sense of direction. Unfortunately, most of us have found ourselves in that situation more often than we would like to admit.

By Joe Glassford. To test the condition of the contacts (excessive resistance from pitting that causes an excessive voltage drop) this voltage drop test should be done: Here we have a fuse located on the “ground” side of the relay switch. This is a common circuit arrangement you will see.
