Understanding Operating Strategies
As driveability technicians, we’ve been taught to solve diagnostic problems by gathering and analyzing data. Data usually comes in three basic forms, the first of which is sensory data that we can see, hear, smell or feel. The second form is measured values gathered by using test equipment like lab scopes and multimeters. The third

Alternators Are the Heart of Import Electrical Systems
In current SAE J1930 terminology, the “alternator” is now being referred to as a “generator.” Of course, this isn’t news for many import technicians because many imports have always been equipped with “generators” for several years. By either name, the alternator’s job has definitely become more complex during the past decade. Years ago, the typical
Volkswagen Brake, Suspension and Exhaust Repairs
The original Volkswagen Beetle changed a number of things for the maintenance technician.

Things have changed

Engine Series: Proper Maintenance Can Extend an Odyssey
We all know that some vehicle owners don’t adhere to preventative maintenance schedules for their vehicles. So when a customer’s vehicle is in for a major problem or service, take advantage of in-depth system inspections. It may be one of the few times that you get to check the vehicle for severely worn parts. Although
Component Connection: Wiper Motors
If there is one system that vehicle owners believe is inhabited by Gremlins, it’s the windshield wipers. Unfortunately, car owners don’t normally realize there is a problem with the wiper system until they need them most – when it’s raining.

Dusting Off Fuel System Fossils:
For many technicians these days, the sight of a real working carburetor may be as alien as the rover roaming the dusty Martian surface. But consider the opportunities that these die-cast, zinc alloy, fossil fuel-metering Martians present to us technicians. Opportunities abound, to repair emissions failures by re-calibrating the main circuits and diagnosing high carbon
