What causes multiple alternators to go bad?
Alternators put out alternating current, and the battery needs direct current to charge, so there is a voltage rectifier that converts it, and it can suddenly go bad, too. Dust and dirt can get into the alternator, and over time cause shorts or wear on the brushes.
How long should a replaced alternator last?
The average longevity of an alternator is seven years or about 150,000 miles. Several factors can impact the lifespan of your alternator, including the quality of the part, the overall condition of the vehicle, and how many electronics are being used.
Do alternators go bad suddenly?
The alternator is a key component in running the electrical systems in your car. When your alternator begins to fail it can cause a variety of different electrical problems in your car, and eventually cause a breakdown. Alternators can go bad suddenly, or slowly over time.
What keeps killing my alternator?
Mechanically a pulley could be off-center and strain the alternator bearings. Or in older cars the tensioner may be adjusted too tightly. If it’s an electrical death, it could be using alternators from a poor source, like some of the marginal alternator recyclers.
Is it OK to buy a remanufactured alternator?
A rebuilt system won’t have all its parts at the same state of wear and tear, but it’s an affordable alternative to buying a new alternator or starter. It’s important to visit a skilled alternator rebuilder or starter rebuilder, because this service requires judgement and experience.
How much does it cost to fix and alternator?
Typically, it costs between $400-$600 to replace a faulty alternator with parts and labour. However, this price usually reflects a remanufactured alternator. New alternators can run you approximately $500 to $1000, again, depending on the type of vehicle you have.
When is it time to replace your alternator?
Your alternator needs to know when each one of those things is plugged in and turned on, so that it can increase power. More importantly, just like with your breathing, your alternator needs to know when to put out less power.
What causes an alternator to wear down over time?
Over time, there are several components in the alternator that naturally wear down. In my experience, it’s either the brushes (magnets) or the voltage regulator that break down the soonest. With the brushes, it’s not very complicated.
Is it time to replace your alternator wrench wench?
Wrench Wench has been in love with automotive mechanics for decades. She loves sharing advice with fellow DIY mechs and curious cats. Alternators are really not complex mechanical components. They are a type of generator that creates an alternating current.
Why is it important to have an alternator in your car?
Your vehicle’s alternator has one extremely important job: Keeping your battery charged. Additionally, your alternator also pumps in a little extra electrical power, so that each electrical system runs optimally. Without your alternator, your battery would drain in a few minutes and your car would stop.
