Diagnostic Dilemmas: Battery-Related Driveability Issues
Any experienced automotive trainer will tell you that the automotive starter battery is the foundation of a vehicle electronics system. Of course, most of us nod our heads in agreement and then proceed to diagnose a driveability problem without first testing the battery’s condition! Unfortunately, short-cut procedures don’t work on the really tough no-code engine
Handling the Load
It takes a lot of amps to power the lights, electric defrosters, wipers, power windows, power seats, power liftgates, the ignition system, fuel injectors, fuel pump, cooling fan, A/C compressor, heater fan, heated seats, audio system and navigation systems on today’s late-model vehicles. Since alternators can generate only so many amps, their output may depend
Vehicle Mileage Maintenance
A mere 0.7 of a mile does not sound like much, it is about 3,700 feet, or less than one-third the distance around Daytona International Speedway. On average, the U.S. population of vehicles will get 20 miles per gallon (including light trucks and passenger vehicles). A 0.7 of a mile improvement represents only a 3.5

Battery, Charging & Ignition System Diagnosis: Getting Around those Difficult-To-Diagnose Faults
What do you really need to know about diagnosing and repairing starting, charging and ignition systems? Basically two things: that electrical and ignition problems are often difficult to diagnose (especially intermittent faults), and that a lot of electrical and ignition parts are unnecessarily replaced in an attempt to repair problems that are hard to diagnose.

Servicing Mazda Electrical Systems: Starting and Charging Diagnostics
While it sounds obvious, the battery is often overlooked when dealing with an electrical problem. Actually, the battery should be more of a maintenance item than a repair issue. I have to think by now all successful import specialist shops are relying on maintenance work to keep their bays profitable. Checking and servicing the battery
Getting to the Heart of 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 technicians because many vehicles 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 vehicle
