What is an alternator?


Ever notice a bunch of lights that flash on your dash when you start your engine? They flash on to test the circuits then go off if everything is working normally. One of the warning lights looks like a car battery. This light informs you if your battery is not charging correctly.

We know that the battery’s job is to store electricity – enough to start your engine and get you moving. But that's about it – you will maybe get a few miles around WORCESTER on battery power alone. An alternator is needed to generate enough electricity to run your engine and power your electrical accessories. For example, the stereo, power seats, heater fan, on-board computers and so on. Not only that, but the alternator needs to recharge your battery. There isn't enough electricity for all of those things if your alternator isn't working properly. When your alternator fails, you aren't going very far.

So what can cause an alternator to not work you may ask? Usually they've simply been worn out. Alternators are driven by your serpentine belt and spin 2 to 3 times faster than the engine – that's a lot of work. The bearings wear out, as do the copper wire coils and magnets that generate the electricity.

It makes no sense in shuffling along with an alternator that's not working properly. You don’t want to be left stranded when it eventually fails. Get a bad alternator replaced as soon as possible. Your WORCESTER, MA service technician at AutoPro Import Repair will install an alternator that meets your manufacturer's specifications.

Who also has a lot of additional electrical gizmos in the vehicle, like computers, DVD players, power inverters and such? Or may regularly tow a camp trailer with a battery that recharges as you drive? If that sounds like you, talk with your WORCESTER service advisor at AutoPro Import Repair about upgrading to a more heavy-duty alternator to meet your needs.
