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

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.

Short-trip, stop-and-go city driving, as well as excessive idling, accelerate the rate at which these contaminants form. Changing the oil and filter regularly and using gasoline that contains an adequate amount of detergent to keep the fuel system,
