Battery Light is on Inspection Service

The battery is one of the most essential components of any vehicle. It is responsible for keeping the car running, as well as powering most of the creature comforts in the vehicle, such as the windows, air conditioning, headlights, interior lights, and radio.

As a result, it’s important to maintain the battery and promptly address any issues that arise with it, which are often indicated by an illuminated battery light.

What does the battery light look like?

The battery light typically takes the form of a picture of a battery on your dashboard, but sometimes it will just be the word “battery.”

Common reasons for this to happen:

  • Faulty or failed alternator: When the battery light comes on, chances are there’s not actually a problem with your battery. Usually it’s a problem with the system that keeps your battery charged. Many battery light issues center around the alternator, which is a generator used for converting mechanical energy into electrical energy. In short, the alternator takes the power that the vehicle’s crankshaft is generating, and converts that power into electrical energy, which it then sends to the battery. If your alternator is unable to produce an adequate amount of voltage, then the battery light will illuminate. When an alternator completely fails, your vehicle is entirely reliant on the battery for electrical energy, which means the car will soon stop running, as spark plugs rely on electrical energy.

  • Bad voltage regulator: The voltage regulator is attached to the alternator and controls how much voltage the alternator is outputting. The voltage regulator limits the amount of voltage the alternator can send to the battery, and also increases the output when the extra voltage is needed. When this regulator breaks or malfunctions, the alternator no longer doles out the correct voltage into the electrical system.

  • Worn-out serpentine belt: The serpentine belt – which helps drive not only the alternator, but also multiple other peripheral devices – can snap, which renders the alternator relatively useless.

  • Corroded battery terminals or cables: While alternator-based issues are the main cause of the battery light coming on, it’s not completely uncommon for the triggering issue to reside in the battery itself. Just like with a battery in a remote, your car battery can die over time. Corrosion on the battery terminals or on the battery cables can also prohibit the battery’s ability to power the vehicle’s electrical unit.

What to expect:

A top-rated mobile mechanic will come to your home or office to determine the source and cause of the battery light, using a voltage meter, amp meter, and load tester to assess whether the issue is in the battery or in the alternator. The battery, alternator, regulator, and serpentine belt are all easily accessible, often making it fairly simple for the mechanic to assess what is wrong with your electrical system.

After the inspection, the mechanic will provide a detailed report that describes the source and cause of the issue, along with the scope and cost of the necessary repairs.

How important is this service?

When your battery ceases to work, your car will stop running. After the battery light has come on, you’ll likely be unable to restart the vehicle or drive it very far without it dying. Enlist the help of a professional to diagnose the issue as soon as possible.

Peter was not only a pro's pro, but he was kind, courteous, patient, and even indulged my curious 6 year old as he watched him work to diagnose our problem. Plus, he diagnosed it correctly, quickly, and took care of everything. Could not recommend higher -- Thanks Peter!

Jose arrived early, had all the tools he needed, was polite and good humored. He figured out the problem in minutes (probably something I should have noticed) and we were able to go pick up the one part that was needed to fix it right then. He did not mind answering all my questions about everything and pointed out items that I should have the previous mechanic shop confirm they did correct (possible over torquing on the alternator nut which sheered off). I would definitely have Jose work on my car again.
