Alternator Replacement

Your vehicle’s engine is probably the first thing that comes to mind when you think of power, 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. A few signs that your alternator might need replacing: The power windows are going up and down a little bit more slowly than they used to, your engine doesn't start as easily or is misfiring, or the headlights 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. 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.


If you notice any of these signs, bring your vehicle into Downtown Automotive in Nelson, BC for a diagnosis. If your alternator is worn, we have a 24 month,  40,000km warranty for alternators installed by Downtown Automotive.


It's important to your vehicle's health to have its alternator putting out the right power consistently because it's a vital part of helping your vehicle run the way it is designed to.
