Why Perform an Alternator Diagnosis Every 5 Years?

The alternator in your car is a generator of electric power and is a major component of your vehicle’s charging system. Whenever your engine is running, the alternator charges your battery and supplies additional electric power for the vehicle’s various electrical systems. An alternator is attached to the engine and is driven by a drive belt (also known as a serpentine belt).

The alternator is a maintenance-free unit. On average, an alternator can last for 8-12 years without any repairs. If an alternator fails, the car may still run on battery power alone, but will die as soon as the battery charge is depleted.

The most frequent symptom of a problem with your vehicle’s charging system is a battery-shaped warning light. Normally this warning light should come on when you turn the ignition, but should disappears as soon as the engine is started. If it stays on, there is a problem with your charging system. The charging system warning light doesn’t point directly to a failed alternator, although alternator problems are very common. You Otobot mechanic will need to do further testing to pinpoint the defective part. Sometimes when the alternator becomes weak, you may notice that your car’s headlights and dash lights become dim at idle, but get brighter at higher RPMs.

Still not sure if your vehicle’s alternator needs servicing? Read our FAQ’s:

If I think my alternator is failing, could Otobots have it tested?

Yes, your Ototbot mechanic can test the state of your charging system with the battery and charging system tester; this is part of our alternator diagnosis test. The test can show if the charging system is weak or not working at all. It also can detect if one of the diodes inside the alternator has failed. If the charging system failed the test, your mechanic will need to do further diagnostic to see if it’s the alternator or something else causing the problem.

How can I make the alternator last as long as I own the vehicle?

Often an alternator can fail prematurely when a protective engine undercover or shield is damaged or missing. This is happens because sand and water from the road can get inside the alternator and cause it to wear faster. If your engine undershield is damaged, have it replaced to keep the engine compartment clean and dry. A coolant or oil leak can also damage the alternator. Similarly, if you have to shampoo the engine compartment, the alternator must be protected from water and detergent.

What are some of the common issues with alternators reported by your technicians?

The most common alternator problems include worn carbon brushes, worn contact rings (the two copper cylinders at the back of the rotor) and a failed voltage regulator. Bad outer and inner alternator bearings (large and small silver cylinders in the cutaway image above) can produce a whining noise. When the alternator is rebuilt, the bearings, voltage regulator, brushes and some other parts are typically replaced with new ones.
