4 Signs it’s Time to Replace the Alternator

Have you ever been stranded on the roadside as your car won’t start? The alternator is one of those parts you can’t afford to ignore. If it malfunctions, you’ll be frustrated. The alternator turns mechanical energy into electrical energy. This powers the car’s electrical systems as well as charging the battery. As you upgrade your vehicle, such as the audio system, among other accessories, don’t overlook the alternator. With high performance alternators, you can ensure a balance, keeping the system in top shape.

Replacing and upgrading the alternator can’t be emphasized enough as you strive to keep the system in good shape. Nonetheless, you need to pick an option that strikes a balance. As you balance, understand what’s too much for the engine, the required amperage for optimal operation, and the available space for the alternator. This will help you to upgrade to the best high-performance alternators, especially as you go for the made-to-order options. Over time, the alternator will wear out. It mostly fails in stages, but don’t wait till you are stranded on the roadside to consider replacing the alternator. Among the signs that you need to give it some attention includes;

Dead battery

A dead battery could be an indication of a worn-out alternator. Nonetheless, even when the alternator is functioning properly, the battery could go bad. Establishing the root cause of the issue is essential to ensure you aren’t upgrading to a high-performance alternator only to be frustrated by a dead battery. A common sign that the alternator is malfunctioning is the battery discharging more frequently than usual. If the damage is extensive, the alternator fails to recharge the battery completely.

Diming/brightening lights

A worn-out alternator disrupts the electric flow. This means that various parts receive too much or less voltage. You’ll notice dimming or brightening of lights. The headlights are the obvious tells as you can easily notice the changes. The effects extend to power seats/windows and dashboard lights. The problem is typically due to a broken alternator or loose connections. Upgrading to high-performance alternators does the trick, keeping the current flow balanced.

Problems with the engine

If you are having a hard time starting the car, more so in cold weather conditions, it might be time for an alternator replacement. Other engine problems associated with the alternators include misfiring, rough idling, stalling, and poor acceleration.


Among the tell tales that the alternator is not in its best shape is unusual sounds. This emanates from the accessory/serpentine belt that connects the alternator to the crankshaft. When the belt loses tension, you’ll hear whining or growling noise. Such noise could also be due to worn-out bushings or bearings.

As the alternators age, it wears out. You can tell if the alternator is defective with the above tells. If you get an ALT or GEN light indicator on your dashboard, don’t ignore it even when your car is running smoothly. Upgrading to high performance alternators makes it easier to keep the power balanced, serving you for an extended period as it doesn’t train to meet your needs.
