What the alternator does
Your battery stores enough electricity to start the engine, and not much more. The alternator generates the power to run the engine and your electrical accessories, such as the stereo, power seats, heater fan, and on-board computers, and it recharges the battery as you drive.
When the alternator stops working, there is not enough electricity for all of that, and the car will not go far.
Why alternators fail
Most simply wear out. An alternator is driven by the serpentine belt and spins two to three times faster than the engine, so the bearings, copper wire coils, and magnets work hard.
The battery-shaped warning light on your dash comes on briefly at startup as a test. If it stays on while you drive, the battery is not charging properly.
A weak or old battery can look like a bad alternator, so we test both before recommending a repair.
Replace it before it strands you
A weak alternator will fail eventually and leave you stuck. We install an alternator that meets your manufacturer’s specifications.
Added electrical equipment or towing
If you run extra electronics such as aftermarket audio, lighting, or inverters, or you tow a camp trailer with a battery that charges as you drive, ask your service advisor about a heavy-duty alternator that fits your needs.
Frequently asked questions
What does the battery warning light mean?
It tells you the battery is not charging properly. It flashes on at startup to test the circuit and should go off. If it stays on, have the charging system checked.
Can I keep driving with a failing alternator?
Only for a short while. The car runs on battery power alone until the battery drains, then it stops.
