Alternator Repair & Replacement Service

Just like any system that uses moving parts, your alternator can wear out, and the components inside can become compromised. A malfunction of the bearings is a common cause of alternator issues. The rotor in the alternator spins freely within the stator thanks to the bearings. As time passes, dust and grime can accumulate, and the heat generated by friction can lead to damage or bearing failure in your alternator. If this alternator issue is occurring, it may sound like a grinding noise coming from under the hood—one sign that your alternator is bad and needs replaced. So, what are the other signs of a bad alternator?

Signs of a Bad Alternator

• Frequent jump starts. Symptoms of a failing vehicle alternator are often confused with a dying battery. You may find that you’re having to jump-start your vehicle frequently and the battery warning light on your dashboard may illuminate.
• Dead battery. Your vehicle battery is altogether dead or can barely start the engine.
• Flickering or dimming lights. If your headlights, dome light or console lights are dimming or flickering, your alternator is possibly the problem.
• Slow electronics. Because your alternator maintains the power of your electronic systems, you may notice power windows opening and closing slowly or your electric seats struggling to move front and back.

If you think you have a bad alternator, take your vehicle to a local NAPA Auto Care so we can check it out, as well as test your car battery. If your battery is in good shape, it is possibly time for an alternator replacement service. However, if it’s bad, we can replace your battery too.

Alternator Replacement Service at NAPA Auto Care

The ASE-certified technicians at NAPA Auto Care are trained to evaluate the electrical systems in a vehicle and determine the next steps in repairing and replacing problem components. If your alternator needs replaced, the technician will start by doing a full inspection and test the starting and charging systems in your SUV, truck, minivan or sedan. This helps eliminate other issues that are possibly leading to the malfunction of your alternator.

If your battery terminals are corroded or the cables are worn or frayed, it may cause a failed alternator test, and these may need replaced. If the issue is more complex, our technicians will administer an alternator test, which could mean partially or entirely removing the alternator from your engine bay. The Auto Care technicians will examine the alternator belt as well and replace it if necessary.
