Is It the Battery or Starter? How to Diagnose a Dead Vehicle


It always happens on a day that you’re running late or not feeling your best. You head out to your car, and it refuses to start! What gives? For the most part, a car that won’t start is likely stemming from your battery or starter, but how can you tell the difference?

When trying to determine the cause, start with your battery. If your battery is the culprit, you likely won’t see any lights or hear any noises when attempting to start up your car. If your headlights or interior lights are very dim, this can mean that the battery is on its way out.

If you attempt to jump-start the car and it starts, it’s an indication that you may need a new battery. But, keep in mind that a dead or low battery can also be caused by a problem with the alternator. Be aware that corrosion, swelling, and the age of the battery may also affect your battery performance. If you notice these issues, your battery may need replacing.

If everything seems to be working properly with your battery, you may have a starter issue. If the vehicle is stalling after it starts or you’re hearing a whining or growling noise from under the hood, you may need a new alternator.

However, for an accurate diagnosis, taking your car to your trusted mechanic professional is your best option. Keep our number in your phone for assistance if you ever encounter problems starting your vehicle. We’ve got your back!
