Your Alternator Just Failed. Now What?
You’re cruising along, when suddenly your low voltage light turns on. Now what?
WHY DO ALTERNATORS FAIL?
Your alternator is your aircraft’s primary source of electricity, and when it fails, you need to start making some decisions. But first, why would your alternator fail?
There are a few reasons, and the first is one of the most common problem: a broken drive belt.
Most aircraft alternators are powered by a drive belt that’s connected to your engine’s crank shaft. And, like everything else on your engine, they can wear out and break. When they do, your alternator comes to a screeching halt, and so does your flow of electricity from the alternator.
