Tech Tip: Understanding Why Alternators and Starters Fail
One reason why alternators have a high failure rate is because they’re always working under a load. Generating electricity to recharge the battery, run the fuel pump, injectors and ignition system, and power all of the vehicle’s lights and other electrical accessories places a substantial load on the alternator that generates a lot of internal heat.

Tech Tip: Diagnosing Starting/Charging Systems
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the same skills.

Current Trends for Ignition Systems
As automotive technology moves forward, ignition systems are becoming more and more entangled with other systems on the engine. The current generation Nissan Maxima 3.5L V6, which was introduced in 2004, has a fairly conventional coil-on-plug (COP) ignition system. The individual coils are driven by the powertrain control module (PCM) using the input signal from
Tech Tip: Sorting Out Tire Pressure Monitoring System Myths
Myths are fine if you’re teaching mythology. However, they are a pain for the automotive aftermarket, especially when dealing with new components like tire pressure monitoring systems (TPMS). With every new technology, there are inherent learning, maintenance and problem-solving issues. Also, there are accompanying apprehensions and fears. Some concerns are valid; others would fall into the category of myths.
Foreign Affairs: Probing Around Subaru Electrical Systems
With station wagons, small multi-purpose trucks and high-powered sports models in its product mix, Subaru has become an obvious choice for multi-use purchasers. And, by building one basic platform with all of the right stuff, Subaru has been able to concentrate on quality. That brings us to the topic of this article, Subaru electrical systems.
Tech Tip: Understanding Vehicle Electrical Systems Begins and Ends with the Alternator
The alternator’s job has definitely become more complex during the past decade. Years ago, the typical import vehicle could live very happily with 40 amps of electrical current, which was enough to power the ignition, fuel and lighting systems. Today, that threshold is rapidly advancing toward 100 amps of current.
Management: Brush Up on Charging System Fundamentals to Help Diagnose Problems
In the modern-day automobile, the battery serves three main functions. First is the obvious: It supplies electrical power to the ignition system, starter, computer system and every other electrical component while the engine is not running (or any other instance when the alternator is not charging).
