Winter is notoriously hard for your vehicle’s charging system. Perhaps you’ve noticed the telltale signs of a problem: dimming headlights, a difficult start etc. Batteries receive the most attention of the charging components, but what about the less talked about parts of the system?
It takes battery power to start your car, but once you’re moving, the engine drives the alternator via a belt and pulley system. The alternator, in turn, keeps the battery charged by supplying it with regulated current. Alternators are mini generators that produce an alternating current (AC) current that must be converted to direct current (DC) by a rectifier or it will damage onboard electrical components and the battery itself. You won’t get very far without an alternator, so pay attention to warning signs of failure such as dimming lights, a dashboard warning, or a weak or dead battery.
The resistance of cold, thick oil causes problems for your battery in cold weather, requiring it to provide more juice to overcome the internal resistance. On a normal day, the alternator requires about 20 minutes of driving to fully recharge the battery; however, on a cold day, it may require more time. One thing to keep in mind here is that when you’re warming up your car, give it a little rev, as some alternators require this extra jolt to start the charging process.
