Some drivers have probably noticed a bunch of warning lights on their dash when they start their engine.  They flash on to test the circuits and then go off if everything’s OK.  One of the warning lights looks like a car battery.  Its job is to tell you if your vehicle’s battery isn’t charging properly.

Most motorists probably know that their battery stores electricity – enough to start the engine and get moving.  but that’s about it – you can only get a few miles on battery power alone.  You need an alternator to generate enough electricity to run your vehicle’s engine and power your electrical accessories, like the stereo, power seats, heater fan, on-board computers, and so on.  On top of that, the alternator needs to recharge your battery.  So when your alternator isn’t working, there isn’t going to be enough electricity for all of those things.  When your alternator fails, you aren’t going very far.

So why would your alternator not work?  Usually they’ve simple 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.

There’s no sense in hobbling along with an alternator that’s not working properly.  It will fail at some point and leave you stranded, then you’ll be wishing you would’ve had an alternator replacement sooner.  You need to get a bad alternator replaced as soon as you possible.  When you come to Express Car Care for an alternator replacement, someone knowledgeable will install an alternator that meets your specifications.  Some drivers use a lot of additional electrical products in their vehicles, like computers and DVD players.  Others may regularly tow a camping trailer that is putting extra pressure on its battery as they drive.  If that sounds like you, you’ll need to think about upgrading to a more heavy duty alternator.  Come in and let us help you figure it out.
