Common Signs that Your Alternator Is On Its Way Out
Your car's alternator plays a crucial role in keeping your vehicle running. It generates electrical power and charges the battery while the engine is running. When the alternator begins to fail, your vehicle’s electrical systems can suffer, and eventually, your car may not start at all. Identifying alternator issues early can help prevent getting stranded. At Lloyd’s Automotive & Transmission Specialists, we provide expert alternator replacement and auto electric repair in the greater Olympia area. Here are four common signs that your alternator may be on its way out and should be inspected by a professional.
Dead or Weak Battery
A failing alternator often leads to a dead or undercharged battery. While batteries naturally wear out over time, if you find yourself needing frequent jump starts, the problem may be with the alternator not charging the battery properly. If your battery is relatively new and you're still experiencing power issues, the alternator is a likely suspect. A mechanic can test both the battery and alternator to determine which one is to blame.
Dimming/Flickering Lights
If your headlights or dashboard lights dim or flicker while you’re driving, your alternator might not be supplying enough power. This can create a serious safety hazard when trying to navigate nighttime roads.
Warning Light on the Dashboard
Most vehicles have a dashboard warning light shaped like a battery or labeled ALT or GEN to indicate charging system problems. If this light comes on while the engine is running, it’s a clear sign something is wrong with your charging system, and quite possible the alternator. Ignoring this warning can lead to sudden electrical failure, so it’s important to get your vehicle inspected promptly.
Problems with Electrical Accessories
As your alternator weakens, you may notice various electrical systems behaving erratically. Power windows may move slower than usual, heated seats might stop working, or your infotainment system could fail. These inconsistencies usually point to an inadequate or unstable power supply, which is a strong sign that the alternator isn’t delivering sufficient voltage to your vehicle’s components.
