Your vehicle’s alternator plays a crucial role in keeping the electrical system running smoothly. It generates electricity to power components like the lights, radio, and air conditioning, while also charging the battery. When the alternator starts to fail, it can lead to several issues that should not be ignored. At Prestige Automotive, we provide expert alternator replacement and auto electric repair in the greater Helena area. Here are five common signs of alternator trouble.

Dim or Flickering Lights

A common early sign of alternator trouble is dim or flickering headlights and interior lights. As the alternator weakens, it struggles to supply enough power to keep all of the electrical systems operating at full strength. 

Dead Battery

A failing alternator can’t adequately charge the battery, leading to dead battery problems. While a battery has a limited lifespan, if yours keeps dying even after jump-starts or replacements, it could be an alternator problem rather than a battery issue. The alternator is responsible for recharging the battery as you drive, and if it’s not working properly, the battery won’t stay charged.

Strange Noises

If you hear unusual noises, such as a grinding or whining sound from under the hood, this could indicate a problem with the alternator’s bearings or belt. A slipping belt that drives the alternator can produce a high-pitched squeal, signaling an issue.

Warning Light on the Dashboard

If the battery or alternator warning light comes on, it’s a clear sign that something is wrong with the charging system. This light may be shaped like a battery or have ALT or GEN written on it. Even if the car seems to be running fine, don’t ignore this warning, as it indicates a charging issue that needs attention.

Electrical Accessory Failures

When the alternator starts to fail, you may notice that your car’s electrical systems are acting erratically. Power windows may be sluggish, the radio might cut out, or the air conditioning may not blow as strong as it should. These electrical failures occur because the alternator can’t produce enough power to keep all the systems working properly.
