International Rectifier has introduced a LIN-controlled alternator-regulator (IRVR101) designed to optimize performance in next-generation intelligent automotive charging systems for increased ...

The days of a simple dc-charging subsystem in a car consisting of an alternator, rectifying diodes, basic regulator, and battery are nearly gone—no question of that. Now, the 12-V automotive regulator ...

Do you own a '69-or-earlier Mopar musclecar? Unless it has already been upgraded, the charging system consists of the old "weak sister" single-field alternator and its accompanying mechanical ...

A common problem exists when driving automotive alternators via motors. In the process of attempting to regulate the charging voltage of a low battery, the alternator shaft torque usually exceeds the ...

There has been a dramatic rise in demand for electrical energy, especially in light vehicles, as mechanical functions are replaced by electronic systems to increase fuel mileage, reliability, and ...

Production cars began using alternators in the 1960s. As part of the electrical system, alternators made it possible for cars to use higher voltage, and led the way to the modern car charging system.

Disconnecting the battery while the engine is running isn't a valid test for alternator function and may damage sensitive electronic parts. Instead, use a common voltmeter and the following test ...

The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also ...

It’s always the same sinking feeling when you notice that the interior lights seem dim as you climb into your Mustang. A twist of the key confirms the miserable truth with a clicking noise from the ...

Last week, I talked about troubleshooting a car-died-while-driving condition on my 1969 Lotus Elan +2, which I eventually traced to a broken contact face—on a set of points that didn’t even have 300 ...

Last week, I talked about how the alternator in my daily driver 2003 BMW E39 530i died while my wife and I were in southern New Hampshire, and how we successfully made the 45-minute trip home just as ...
