Righter’s Auto Repair advises that the maximum voltage and alternator should generate is 14.5 volts. Have your vehicle towed to our shop if the alternator is overloading the electrical system. You should also have the alternator tested if you notice any of the following problems.

Dashboard Warning Light

Sometimes, when the alternator starts to go bad, the engine control module will turn on a dashboard warning light. The light may be in the shape of a battery or may say ALT or GEN. take this warning seriously, as it can be a sign that the alternator is on its way out.

Difficult Starts/Dead Battery

If you have been having problems starting your automobile lately because the battery keeps dying, the alternator may no longer be able to keep the battery charged. This is just one of the responsibilities the alternator has aside from generating electricity.

Frequent Engine Stalling

Another thing the alternator is responsible for is the spark plugs. It provides power to them so they can generate sparks to start your engine and keep it running. If your engine has started to stall frequently and you can hear it misfiring, the alternator may not be powering the spark plugs.

Growling, Grinding, or Whining

The alternator may start to make noises if it is going bad. For example, you might hear growling or grinding in the engine. This is an indication that the alternator is wearing out. Whining or squealing noises point more toward the alternator belt as the problem.

Malfunctioning Accessories

The alternator is also responsible for providing power to your car, truck, or utility vehicle’s power accessories. This includes things like the entertainment system and the power seats. If these accessories start to malfunction, slow down, or shut off by themselves, your alternator could be the source of the problem because it is going bad.

Vehicle Light Problems

Finally, the alternator helps to provide power to the lights so they shine brightly. If you are having problems with your exterior and interior lights, it’s possible that the alternator is failing to produce the power they need. For example, your headlights may be dim at night.
