Dead Battery

It is frustrating when you have somewhere to be, and your car will not start. It can also be scary when your battery light comes on while driving. When car issues arise, knowledge is important to get your car running again and get moving as soon as possible. 

You can look for multiple signs to determine if your battery or the alternator is the culprit. Below are some common signs of battery and alternator problems.  

Dim Dashboard Lights

If you have access to a dashboard battery gauge, determine if there is a charge. The car does not need to be running for this. When the lights are dashboard lights are dim, this is an indication that the battery is bad. Find your Ford F600 battery to get back on the road.

Battery Age

Batteries do not last forever. If your battery is between three to five years old, it may be time for a replacement. Older batteries start to corrode inside and cannot hold a charge like a newer battery. 

Battery Corrosion

Clean the battery by using a rag to wipe away any corrosion. Jump-start the car. Allow the car to run for a little while and then turn it off. Try restarting the car. If it will not start without a jump at this point, it is likely the battery. Find the best 1999 Chevrolet S10 battery option to get your car running now.

Engine Starts but Dies Immediately

Check your battery first if your engine starts but dies immediately. The battery may only produce enough power to start the car, but cannot keep the car running.

Your alternator charges your battery. The battery will not hold a charge when the alternator is going bad. Below are a few signs that the alternator is faulty.

Engine Doesn’t Crank

Once you know the battery can hold a charge with the above steps, but the engine will not start, it is likely an issue with your alternator. When your car stalls immediately after a jump, it is a clue the alternator is not working.

Headlight and Interior Light Issues

When your headlights provide inconsistent results such as flickering or brightening and dimming, this is a sign that the alternator is causing the problem. The interior lights may also dim with the engine running.

Battery Is Dead

A dead battery is a sign that the alternator is the concern and not that you necessarily have a bad battery. The alternator’s main purpose is to charge the battery. When this does not happen, the battery will not do its job. This is a good indication that the alternator needs to be replaced.

Electrical Issues

A faulty alternator can cause issues with the electronics in your car. For example, your speedometer may show signs of an issue, your radio may sound strange or your window may function slowly.
