The electrical system of your car relies heavily on the state of your alternator. As the vehicle’s electrical system and accessories consume power, the alternator must stay in check, or the vehicle may be at risk of power failure.
To help you pinpoint when it may be time to consider high output alternators, here are some things to think about.
Signs Your Alternator Is Failing
Your alternator may be failing if you notice:
- poor car audio
- light dimming when stereo is on
- car starting then stalling
- engine squealing or whining
- burning rubber smells
- the battery warning light is on
- car fails after being jumpstarted
- slow-functioning accessories like slow-moving windows
Why Choose High Output Over Regular Alternators?
Alternators create the electrical current that allows the vehicle and all of its components to function correctly. The more advanced these components are, the greater power your alternator must produce to keep the car working.
High output alternators are installed to increase total amperage to the car’s electrical system. Sometimes these are needed to preserve battery power or supply the vehicle with the necessary electrical output to run correctly.
If you’ve upgraded your sound system, you might require a high-output alternator given the extra energy needed to run the system and the rest of the car.
Things To Note
If you’re worried that your high output alternator will be too powerful and put out more energy than is necessary, you’re wrong. Here’s why:
- The amperage rating indicates what the alternator is capable of, not what it will put out when that amount of power is not needed.
- The alternator will only respond to the actual needs of your car. If your electronics equate to a 60A, your alternator will only support that, not its total amperage.
- In most cases, the stock alternator is enough to keep your car functioning. It is when you add aftermarket equipment that you should consider a high-output alternator.
- Larger vehicles are most equipped to handle high output alternators.
- If you own an economy car, you won’t want to exceed 300 amps. If your car has a small engine, it might not operate an alternator with that amperage.
Review the data on your vehicle to see what alternator will work for you. A high output alternator might be just what you need to power up your sweet ride.
