Is my alternator bad? Here are 7 signs

A healthy alternator will reliably charge up your car battery. If your alternator is malfunctioning, your battery's power reserve could become depleted to the point that you're unable to get moving. When you first suspect alternator trouble, you'll want to take action to address it. By being proactive, you could save yourself from getting stranded. Here's a look at seven common signs of alternator failure.

Dead Battery

Car batteries should last for three to five years. If yours dies sooner than this, then there's reasons to suspect alternator trouble---unless of course you left your headlights on!

Dashboard Indicator Light

If a light illuminates on your dashboard that reads ALT or GEN, then alternator trouble could be brewing. In some vehicles, this warning light turns on in the form of a small battery.

Electrical Accessory Problems

In newer vehicles, the computer will often prioritize what accessories will get shut off if the alternator isn't supplying sufficient power. This way, there will be enough power for essential functions. So, if your power windows start to roll up and down at a noticeably slower rate, it could mean that your alternator isn't working properly.

Malfunctioning Headlights

It's your alternator that gives your headlights their power to shine. If your alternator is malfunctioning, then your headlights may exhibit erratic behavior, such as dimming and flickering.

Belt Problem

You may have found the source of your alternator trouble if you've spotted a belt that is too tight, too loose, or cracked.

Stalling Out

If your alternator isn't supplying enough power to your spark plugs, then your vehicle could stall out while you're out in traffic.

Burning Smell

The alternator's drive belt is kept under a lot of stress and as it wears out, it may emit a burning odor. And when an alternator is overworked, it could push an excessive amount of power through its wires, which may create a burning smell and a safety concern.
