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.

Tech Tip: Replacing Wheel Bearing Hubs Equipped with Wheel Speed Sensors
When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside world.
Tech Tip: What To Do When An Engine Won’t Start
In today’s world of high-tech electronics, onboard diagnostics and scan tools, you would think engine diagnostics would be easier than ever. Yet some technicians struggle when confronted with an engine that cranks, but refuses to start. Most no-starts do not generate any fault codes, so how do you proceed to find out what’s causing the problem?

Diagnostic Solutions: COP Ignition Systems
For a number of reasons, the trend of modern engine management technology is leaning toward using coil-on-plug (COP) ignition systems. One reason is that COP ignitions are very compact and are very adaptable to individual cylinder tuning. With the exception of a few designs that incorporate a driver or “module” into the COP assembly itself,
