Your Vehicle's Other Power Plant (Alternator Replacement)
March 2, 2025
Your vehicle's engine is probably the first thing that comes to mind when you think of a power plant. But it has another power source that is vital as well: the alternator.
The alternator is what puts out the electricity that powers such things as your lights, power windows, sound system, and navigation. Maybe you've started seeing those electrical components behaving in strange ways. Maybe your power windows are going up and down a little bit more slowly than they used to. Or perhaps your engine doesn't start as easily or is misfiring.
Other signs of a failing alternator are headlights that are either brighter or dimmer than usual. If your battery keeps going dead, it could be that the alternator isn't recharging it.
The alternator has to get its power from somewhere, and in vehicles with internal combustion engines, that power comes from a drive belt powered by the engine. Sometimes that belt can fail. If you hear a whining sound, it could mean bearings in the alternator aren't turning as freely as they used to. You could even notice a burning smell. Oh, and when you see your battery light illuminated on your dash (it looks like a rectangle with a - and + inside), it may be warning you that your alternator is not healthy.
Bring your vehicle in to us for a diagnosis if you notice any of these symptoms. If your alternator is bad, we can recommend a new or remanufactured one to replace it. Some new alternators are warranted for life and remanufactured units usually are guaranteed as well.
It's important to your vehicle's health to have its alternator putting out the right power consistently. It may not be as well known as the other power plant under the hood, but it's a vital part of helping your vehicle run the way it is designed to.
