Yes, it’s a snoozer of a topic. But that’s great news. As aircraft alternators have quietly become more long-lived, they get less and less attention from owners who, rightfully, focus on the components that give them fits by breaking with frustrating regularity or require repetitive inspection or replacement. That’s good, especially as some owners now have a second alternator in their airplanes to provide a backup power source as part of going to an all-electric panel and getting rid of a component that is definitely less reliable than an alternator-the vacuum pump.
